1. In addition, gallium nitride has the advantages of high heat dissipation, small size and small loss. If gallium nitride can be developed, it will not be a problem to replace silicon-based chips. Gallium nitride can be used in chargers, components, etc. Silicon-based chips dominated the chip world for decades, and it was Americans who developed the silicon material and mastered the patented technology.
2, nm chip is not the limit. In the future, the materials used to make chips may be more diverse. At present, mostThe chips are all based on silicon, and the accuracy of silicon-based chips can only reach 1nm.
3, fast. The silicon-based optical chip developed by Yandong Micro is an AI computing power chip that processes information and signals collected 1,000 times faster than electronic chips. A chip is a tiny circuit with a special function, made up of a large number of transistors.
In the manufacturing process, although the process and complexity of the two are similar, the photonic chip has structural requirementsNot as harsh as electrical chips, usually hundreds of nanometers. Therefore, photonic chips do not have to use extreme ultraviolet lithography (EUV), as electronic chips do.
High resolution: Nano imprinting technology can achieve high resolution pattern transfer, and effectively solve the resolution bottleneck problem caused by the light source limitation in optical lithography technology. This allows nanoimprint technology to meet the needs of the next generation of chip manufacturing for finer structures.
The "bottleneck" of China's chip technology is that China has no core technology and independent research and development capability in the field of chip technology, and there is no leading chip from material, design to production systemPrepare any link in the complete set of technologies.The lithography machine, the lithography machine of the photoresist manufacturing chip, the accuracy of which determines the upper limit of the chip performance.
The number of nanometers of a chip refers to the manufacturing process of the chip, or the size of the transistor circuit, in nanometers (nm). It's a unit of length in nanometers. In processors, that means the distance between transistors is the pitch. The smaller the distance, the more transistors can be integrated in the same size area.
Note that the feature size here refers to the smallest structural size that the process can accurately control, and does not mean that the chip is so largeDifference between fiber and chip action

3, with pure silica can be drawn out of high transparency glass fiber. The laser can be transmitted forward through countless total reflections in the path of the glass fiber, instead of heavy cables.
4, the production method of monocrystalline silicon is usually the first to prepare polysilicon or amorphous silicon, and then grow rod monocrystalline silicon from the melt by direct-pull method or suspension zone melting method. Monocrystalline silicon is mainly used to make semiconductor components. Properties of silica: SiO2 is also known as silica. Widely distributed in nature, such as quartz, quartz sand and so on.
5, the common use of silica is to make optical fiber, silicon isMaterials for electronic chips and solar cells.
2, silicon is a semiconductor, silicon single crystal is the basic material of the chip, mainly the use of silicon semiconductorQuality.
3, What is optical chip? The researchers combined the light-emitting properties of indium phosphide and the optical routing capabilities of silicon into a single hybrid chip. When a voltage is applied to indium phosphide, light enters the silicon wafer's waveguide, producing a sustained laser beam that drives other silicon photonic devices.
4, the application of different photoelectric chips: photoelectric chips are mainly used in the communication industry, is an indispensable part of the communication equipment system. Ordinary chips: Ordinary chips are mainly used in the semiconductor industry, such as CPU, storage, flash memory and so on.
5, quick. Silicon base developed by Yan DongweiThe optical chip is an AI computing power chip that processes the collected information and signals 1,000 times faster than the electronic chip. A chip is a tiny circuit with a special function, made up of a large number of transistors.
