Description
TECHNICAL FIELD

Embodiments described herein generally relate to an integrated circuit and method, and more particularly to an integrated circuit and method that utilize a shape memory material.


BACKGROUND

Conventional integrated circuits and methods typically include rigid flex packages that are manually folded into their final and unchangeable state. In addition, conventional integrated circuits and methods sometimes utilize flexible hinges, joints and cabling to connect rigid sub-assemblies.


The types of known integrated circuits and methods are usually limited in package design, and have problematic issues with balancing stress and deformation response for different applications. In addition, conventional integrated circuits and methods are typically unable to provide flexibility in packaging and applications that require changing physical configurations.


The development of cloud computing, smart sensors, flexible electronics and all other supporting technologies should lead to an expansion in the number of computing applications across different market segments in the future. However, as the devices become thinner, lighter and smaller, innovative design and manufacturing processes may be required in order to meet the various complex exterior shapes/contours that will be needed for final electronic products. The need for flexibility in the shape of electronic systems is ever increasing such that there is a need for devices that may take more than shape (e.g., during operation of the electronic system or for packaging of the electronic systems—among many other potential applications).

The order of operations for the method [100] will also depend in part on whether the shape memory material is metallic or a polymer (i.e., compare FIGS. 3A-3E with FIGS. 5A-5D). In addition, the shape memory material may or may not be trained depending on where and when the various operations of the method [100] take place.


In some forms, no activation of the shape memory material takes place during assembly to another device in order to simplify the assembly process. The shape memory material may be prevented from activation either by attaching the shape memory material near the end of the assembly process or selecting a shape memory material with a high activation temperature that is not reached during the assembly process. It should be noted that forms of the method are contemplated where the shape memory material gets activated and physically deforms to a final shape after a system level test or during end consumer use (among other applications).
