TECHNICAL FIELD

This application relates to a technology in the microelectronics field, for example, to a micro-nano wire manufacturing device and a micro-nano structure.

BACKGROUND

Micro-nano patterns or micro-nano wires manufactured on a specific substrate by using liquid-phase nanomaterials have great research prospects in integrated circuits, optical microelectronic devices, biosensors, and biodetectors. The performance of devices in these fields depends largely on one-dimensional micro-nano patterns or micro-nano wires. For example, micro-nano patterns or micro-nano wires made of organic materials can improve the balance of electron and hole transfer, thereby improving the performance of the integrated circuits and the optical microelectronic devices.

In recent decades, there are many methods for manufacturing one-dimensional micro-nano patterns or micro-nano wires, such as photolithography, micro-contact printing, inkjet printing, etc., However, these methods are costly and have a complex process. Moreover, micro-nano patterns that can be manufactured by using these methods are limited. Usually only some designed patterns can be transferred to the substrate. In addition, it is difficult to manufacture nanoscale patterns by using these methods. In the related art, the drip method is generally used to manufacture nanoscale patterns. However, the drip method has a low success rate and a small area in manufacturing micro-nano wires, and the shapes, directions, and positions of the micro-nano wires are random and uncontrollable in the drip method.

The ends of the two animal hairs 600 hang down and abut against each other at the hanging portion. The range of the angle between the projections of the two animal hairs 600 on the substrate 800 is 1° to 5°.

It is to be noted that as shown in FIG. 2, that the micro-nano wire applying mechanism includes two animal hairs 600 means that two micro-nano wire applying mechanisms are provided, and each micro-nano wire applying mechanism may be one animal hair 600. Similarly, in some embodiments, that the micro-nano wire applying mechanism includes at least two flexible wires means that at least two micro-nano wire applying mechanisms are provided, and each micro-nano wire applying mechanism is one flexible wire.

It is to be understood that as shown in FIG. 2, that the two animal hairs 600 abut against each other at the hanging portion means that the ends of the two animal hairs 600 hang down to an end of the substrate 800, are against each other and are adjacent to each other. Similarly, in some embodiments, that one ends of two flexible wires hang down to the substrate and abut against each other means that the one ends of the two flexible wires hang down to the substrate, and the one ends of the two flexible wires hanging down to the substrate are against each other and adjacent to each other.

In some embodiments, the micro-nano wire applying mechanism optionally includes multiple groups of flexible wires (such as animal hairs 600), and each group includes two flexible wires.

In the same group of flexible wires, one ends of two flexible wires hang down to the substrate and abut against each other.

In some embodiments, the liquid-phase nanomaterial storage device 500 is connected to a motion actuator through a bracket, and the motion actuator is configured to drive the liquid-phase nanomaterial storage device 500 to move. In some embodiments, the surface of each flexible wire has regularly distributed microstructures.

In some embodiments, the liquid-phase nanomaterial storage device 500 is securely connected to the Z-axis linear displacement mechanism 300 through the bracket 400 and can move stably on the Z-axis linear displacement mechanism 300, the Z-axis linear displacement mechanism 300 is connected to the Y-axis linear displacement mechanism 200 and can move stably on the Y-axis linear displacement mechanism 200, the Y-axis linear displacement mechanism 200 is connected to the X-axis linear displacement mechanism 100 and can move stably on the X-axis linear displacement mechanism 100, and the X-axis linear displacement mechanism 100 is secured to a stable platform.

As shown in FIG. 1, in some embodiments, the motion actuator includes a pair of X-axis linear displacement mechanisms 100, a Y-axis linear displacement mechanism 200 erected on the pair of X-axis linear displacement mechanisms 100, and a Z-axis linear displacement mechanism 300 erected on the Y-axis linear displacement mechanism 200. The Z-axis linear displacement mechanism 300 is configured to drive and displace the liquid-phase nanomaterial storage device 500 in the extension direction of the Z-axis. The Y-axis linear displacement mechanism 200 is configured to drive and displace the liquid-phase nanomaterial storage device 500 and the Z-axis linear displacement mechanism 300 in the extension direction of the Y-axis. The X-axis linear displacement mechanisms 100 are configured to drive and displace the liquid-phase nanomaterial storage device 500, the Y-axis linear displacement mechanism 200, and the Z-axis linear displacement mechanism 300 in the extension direction of the X-axis.

It is to be understood that the X axis, the Y axis, and the Z axis are three coordinate axes perpendicular to each other.

In some embodiments, the X-axis linear displacement mechanisms 100, the Y-axis linear displacement mechanism 200, and the Z-axis linear displacement mechanism 300 are all programmable linear displacement mechanisms, such as linear motor modules, which can accurately control the movement direction and movement speed of the animal hairs 600 and the pressure of the animal hairs 600 relative to the substrate.

In some embodiments, the distance between the roots of the two animal hairs 600 is 1-3 mm.

The angle and distance between the animal hairs 600 and the substrate 800 can be adjusted through rotation of the liquid-phase nanomaterial storage device 500 relative to the bracket 400. In some embodiments, the angle between the tangent of the roots of the animal hairs 600 and the substrate 800 is 20°-70°, and the vertical distance from the roots to the substrate is less than 7 cm.

The operating principle of the embodiment of this application is as described below.

The liquid-phase nanomaterial flows into the gap between the two animal hairs 600 through the liquid outlet 501 under the action of gravity.

When the animal hair 600 contacts the substrate 800, the liquid-phase nanomaterial in the gap is continuously and controllably transferred to the substrate 800 under the action of gravity, the Laplace pressure difference and the asymmetric retention force, so that a micro-nano wire 700 with a uniform width is formed. The micro-nano wire 700 has the same functional properties as the liquid-phase nanomaterial.

The shape of the micro-nano wire 700 varies with the motion track of the animal hairs 600. The width and thickness of the micro-nano wire 700 can be both under nanoscale control. The thickness of the micro-nano wire 700 depends on the movement speed, the length of the hairs and the surface tension of the liquid. In some embodiments, the micro-nano wire 700 has a width of 50-1000 nm and a thickness of 40-150 nm.

In some embodiments, each flexible wire may be made of animal hair.

Optionally, a hinge structure with a controllable rotation angle is adopted.

In some embodiments, the motion actuator includes a pair of X-axis linear displacement mechanisms, a Y-axis linear displacement mechanism erected on the pair of X-axis linear displacement mechanisms, and a Z-axis linear displacement mechanism erected on the Y-axis linear displacement mechanism. The Z-axis linear displacement mechanism is used to control the pressure of each flexible wire relative to the substrate, thereby controllingso that the width of the micro-nano wire is controlled.

In some embodiments, the motion actuator may be a robot, such as a parallel robot or a serial robot.
