Q:The metal in the silicon wafer
The properties of silicon have excellent electrical properties. The band gap is moderate, and is 1.21 ev. Higher carrier mobility, the electron mobility is 1350 cm / sec / V /, hole mobility is 480 cm / sec / v. The resistivity at room temperature (300K) up to 2.3 x 10 - Europe - cm wide, doped resistivity can be controlled in 10 - to 10 - Europe - cm, can meet the needs of manufacturing various devices. The minority carrier lifetime of the single crystal silicon is longer than that in a few tens of microseconds to 1 milliseconds. Larger thermal conductivity. The chemical property is stable, and is easy to form a stable thermal oxidation film. It can be used to realize the surface passivation and protection of the PN junction in the fabrication of planar silicon devices, and the metal oxide semiconductor structure can be formed to produce MOS field effect transistors and integrated circuits. The properties of the PN junction has good characteristics, so that the silicon device has the advantages of high pressure, the reverse leakage current, high efficiency, long service life, good reliability, good heat conduction, and in the 200 - high temperature operation etc..
Q:What's the difference between a silicon wafer and a battery?
Silicon chip, is a large piece of silicon, cut into a filmSolar cell, the mainstream is the silicon wafer made of crystalline silicon solar cells, or other solar cells: thin film solar cells, amorphous silicon solar energy, solar cells and so on
Q:What is a silicon chip made of?
The silicon rod pulling ingot is finished, the silicon wafer, and then processed to solar cell sheet, processing factory is finished, then the solar street lamp assembly
Q:How to make the photoresist and silicon substrate adhesion better
A thin layer of HMDS (hexamethyldisilazane) can be applied on the bottom layer of the silicon wafer, and then coated with PR, the main function of the solvent is to make the surface structure of the SIO2 of the silicon chip to be changed from hydrophilicity to hydrophobicity
Q:How many times is the resistance of the same size silicon
Silicon is one of the largest and most widely used semiconductor materials, and its output and consumption mark the level of a country's electronics industry.
Q:What is the surface hardness of monocrystalline silicon and polycrystalline silicon wafers
When the contact depth is above 60NM, silicon wafer contact stiffness and contact depth of a linear relationship between the hardness and elastic modulus remained unchanged, the measured value of hardness and elastic modulus of silicon, are about 12.5GPa and 165.6GPa.
Q:What is the meaning of the wafer (100), the crystal orientation index or the crystal plane index
The coordinate system is set up in the crystal cellIs the coordinate of the direction vector
Q:What are some of the silicon wafer factory
The following is a silicon production company series positions distribution table, you can refer to the 1 equipment management department manager deputy manager of electrical equipment equipment maintenance engineer mechanical equipment maintenance Engineer Association and insurance technician equipment management maintenance team leader electric operation monitor operation duty electrician maintenance electrician maintenance mechanic subtotal
Q:The purpose and means of chemical etching of silicon wafers?
What are the means of chemical etching of silicon: 1 acid corrosion of 2 alkaline corrosion
Q:What is a silicon wafer
Silicon is an important material in the IC fabrication, through photolithography and ion implantation on the silicon wafer and other means, can be made into various semiconductor devices made of silicon chip. With amazing computational capabilities. The development of science and technology promotes the development of semiconductor. Development of automation and computer technology, this makes the silicon chip (integrated circuit) high technology product cost has been reduced to a very low degree. This makes the silicon wafer has been widely used in aerospace, industry, agriculture and national defense, and even crept into every family.
