Description

PRIORITY CLAIM

The present application claims the priority of China application no. 201410152132.6, filed Apr. 15, 2014, which is incorporated herein by reference in its entirety.

BACKGROUND

In general a device is defined by a plurality of layer feature compositions in accordance with sort of properties and relationships, in which the definition is represented by a sample graphical layout file and several description files. A sample device is to reflect its physical composition and structure fabricated onto the wafer, therefore is regarded as a golden reference throughout the design and manufacturing processes, for example, a DRC (design rule check) used for detect the design rule violation according to the device property, or a LVS (layout versus schematic) used for identifying a device connectivity and checking against the schematic. However, the sample layout and description files are manually processed and may be wrongly interpreted, which would resulted in a series of fatal misoperation throughout the whole IC manufacturing.

Based on the manual inspection, the deck, e.g., DRC deck, and script, e.g., pcell layout synthesizing, used in the IC design processes can be created accordingly for ensuring the product produced meets the intended product of the customer. As device designs become more complex, additional layers and features are included in device specifications. The increase in features and layers in a device increases the complexity in determining the device type and properties. As a number of device types increases, the deck and script creators refer to many different reference files in order to determine the device type and properties.

In instances where the deck and script creator inaccurately determines a device type or device property, a product is either re-worked or wasted. If the deck or script creator inaccurately determines the device type or the device property, the device specifications are again reviewed manually to identify and correct the error.

DETAILED DESCRIPTION

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. For example, the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

FIG. 1 is a flow chart of a method 100 of extracting device type and properties, in accordance with some embodiments. Method 100 begins with operation 102 in which an input file is received. The input file includes specification of several features used to form a device. The features are arranged across one or more layers of the device. In some embodiments, multiple features are present in a same layer. In some embodiments, an interface of separate features exists at a surface of a layer. In some embodiments, a layer of the device is defined by depth of the feature in a wafer or substrate or a height of the feature above the wafer or substrate. In some embodiments, a layer of the device is defined by a pre-determined depth into the wafer or substrate or a predetermined height above the wafer or substrate. In some embodiments, the input file is a graphic file. In some embodiments, the input file is a graphic design system (GDS) file or an open artwork system interchange standard (OASIS) file. In some embodiments, the input file identifies the layers of the device. In some embodiments, the layers of the device are identified using a processor associated with a general computing device.

FIG. 2 is a graphical design system (GDS) file 200 received from a device creator, in accordance with some embodiments. GDS file 200 is a non-limiting example of an input filed received in operation 102 (FIG. 1). GDS file 200 includes device specifications for a high-voltage (HV) transistor. The HV transistor of GDS file 200 includes several different features, such as doped wells, doped bodies, isolation features and a gate structure, where the feature is presented in a geometrical shape, e.g., polygon, onto a GDS with a specific layer name or a layer number. The features of GDS file 200 have different physical cross section structure, e.g., depths into a substrate of the HV transistor or heights above the substrate of the HV transistor. In some embodiments, a layer of GDS file 200 is defined based on the depth or the height of respective features. In some embodiments, a layer of GDS file 200 is defined based on a predetermined depth or height of the substrate of the HV transistor.

Returning to FIG. 1, method 100 continues with operation 104 in which features of the device are extracted from all layers of the input file. A feature is defined as a geometrical pattern, which can be composed of a single layer pattern or a logical operation of a plurality of layers, in which the layer is represented by a layer name or layer number. The features are extracted using a processor associated with a computing device. Extracting the features enables identification of the features by the computing device. In some embodiments, the features are extracted using an electronic design automation (EDA) tool. In some embodiments, the features include structures such as doped wells, doped bodies, gate structures, isolation structures, or other suitable device structures, all of which represent different fabrication parameters such as dopant types, dopant concentrations, or materials. In some embodiments, the features include a grouping of structures or layers.

In operation 106, a mini-tech file is generated based on relationships between the extracted features. The mini-tech file is generated by a computing device. In some embodiments, the mini-tech file is generated using the EDA tool. The mini-tech file enables identification of a device type for the input file.

The mini-tech file is generated using relationships between the extracted features. The relationships between the features are determined using logic operations and positional parameters. In some embodiments, the logic operations include Boolean logic operations. In some embodiments, the logic operations include AND operations, meaning two or more features are included in a same layer; OR operations, meaning at least one of two or more features are included in a same layer; NOT operations, meaning at least one feature is absent from a layer; BUT operations, meaning one feature is present in a layer and at least one other feature is absent from the same layer; or other suitable logic operations.

The positional parameters are used to determine a relative position of the features within a same layer of the device, in which the layer may be a primitive layer used in mask making or a derived layer from a logical operation of multiple layers. In some embodiments, the positional parameters include fully separated, meaning a separation distance exists between two analyzed features; separated but touching, meaning an interface exists between the two analyzed features, but the features do not overlap; overlapping, meaning at least a portion of a first feature is included in a same area as at least a portion of a second feature; enclosed, meaning that a first feature is surrounded by a second feature; or another suitable positional parameter. The combination of logic operations and positional parameters enables determination of the presence and position of different features within a certain layers.

In operation 108, layer set relationships are analyzed. A layer set represents a physically grouped layers, for forming a basic device structure, of a device among one to multiple devices onto a same input file (e.g. GDS). A layer set includes at least two layers, wherein the inclusion layer has at least one feature in that given layer which physically interacts with other layer feature in the same layer set. The layer set relationships include comparison of the presence and location of features in two distinct layers. In some embodiments, operation 108 is limited to analyzing adjacent layers. In some embodiments, operation 108 includes analysis of adjacent layers and non-adjacent layers, i.e., layers which are separated from one another by at least one other layer. Results from the layer set relationship analysis are stored in a non-transitory computer readable medium.

A device type is determined using the layer set relationships in operation 110. The device type is determined by comparing the analyzed layer set relationships with template layer set relationships. In some embodiments, the device type is determined using an EDA tool. In some embodiments, the device type is determined by comparing the layer set relationship from operation 108 with a device type database. In some embodiments, the device type is determined by comparing all analyzed layer set relationships with the template layer set relationships. In some embodiments, the device type is determined by comparing less than all analyzed layer set relationships from operation 108 with the template layer set relationships. In some embodiments, analyzed layer set relationships from operation 108 are compared with the template layer set relationships until the device type is determined and then comparisons are ceased. In some embodiments, the template layer set relationships include characteristic layer set relationships which are unique to a specific device type, where the characteristic layer set may refer to a single primitive layer identity or a derived layer identity from multiple layers. In some embodiments, comparisons are limited to the characteristic layer set relationships.

In operation 112, the mini-tech file is updated with device properties. The device properties are determined based on the layer set relationships analyzed in operation 108 and the computation results 114. In some embodiments, the device properties include computation results 114 of pattern width, length, and area, or another suitable device property. The mini-tech file is updated by incorporating the device properties with the device type. The mini-tech file is updated using a processor in a computing device.

A computation is performed on the updated mini-tech file in operation 114. The computation determines the dimensional and geometrical properties of the device. In some embodiments, the computation determines pattern width, length, and area, or other applicable dimensional and geometrical parameters. The device properties included in the mini-tech file in operation 112 are based on the layer set relationships analyzed in operation 108 and the computation results 114. By comparing the layer set relationships in the mini-tech file to the computation results, the device is able to be evaluated to determine the variety between layer sets. In some embodiments, the mini-tech file is updated by an iterative computations with modified device properties based on results of the computation by repeating operation 112. In some embodiments, operations 112 and 114 are repeated until all the device properties are obtained. In some embodiments, the computation is performed using a binary executable, a shell script, an EDA built-in call-back function, or another suitable software tools.

In operation 118, an output file is generated based on the device properties. The device properties are confirmed to meet the device specifications of device creator. The output file is generated to be readable by other design verification and quality assurance tools. In some embodiments, the output file is a text file. In some embodiments, the output file is a device physical property abstraction view, wherein a device physical property abstraction view describes the location and relative position of various features within a device may be a text file format, a compiled program data structure, or a specific EDA tool compliance format. The output file is stored on a non-transitory computer readable medium.

In operation 120, the output file is provided to design verification and quality assurance tools. In some embodiments, the design verification tools include a design rule check (DRC) tool, a layout versus schematic (LVS) tool, a process design kit (PDK), or other suitable device design tools. In some embodiments, the output file is provided to each design tool by a same computing device, such as an EDA tool. In some embodiments, the output file is provided to at least one design tool by a different computer device from a computing device used to provide the output file to a different design tool. In some embodiments, the output file is provided to a display to enable observation.

In comparison with manual analysis of an input file, method 100 decreases analysis time by increasing comparison rate for different features in different layers. Method 100 also increases the precision of input file analysis in comparison with manual analysis. Method 100 also provides a single output file or a plurality of abstraction views for use by several different design tools.

By providing an automated tool for identifying a type of device, method 100 enables a semiconductor manufacturer to determine whether a device designed by a device designer is properly defined in according design tools, e.g., DRC tools and LVS tools. In addition, by analyzing the input file using an automated tool, template layer relationships are updatable to enable faster analysis of future device revisions. Creating a customized device database for input files to manage the varieties and similarities between devices helps the semiconductor manufacturer to provide high quality product and accurate analysis for different customer orders.
