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 to do on the silicon wafer
3, water cleaningThis step is very important! Do not wash the water in order to save trouble after the end of washing. Rinse the small dust, particles, and other debris washed off during the scrubbing process.
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
In some places, the resistance of the epitaxial layer is adopted, and the resistance is N type, which has a lot of inconvenience in the circuit, and the numerical value is also very difficult to do
Q:How to make a resistor on a silicon chip (integrated circuit)
Method for making the Baidu transistor circuit.Simply by laser, and method of mixed batch chemical piling up complex circuit
Q:Is a wafer a silicon wafer and a wafer?
Ion implantation, etc., can be made into various semiconductor devices
Q:I would like to ask what the purpose of the use of semiconductor silicon wafers, doped with boron ah?
High purity silicon wafers for use in electronics and solar energy are required to be doped with boron to manufacture the P end of the P - N junction, in which P (P) - N (As) -, Ga (B) - gallium (III) indium (III) - silicon.
Q:Consult the difference between silicon and battery
Silicon wafer is generally refers to the silicon ingot with diamond wire or just cut into pieces,
Q:The relationship between the weight and the power of solar wafers!
The thickness of the silicon wafer is unchanged and the weight is unchanged:156*156,8 inch polycrystalline silicon chip efficiency reached 16%, single-chip power of 3.89W.This can be pushed: the thickness of the silicon wafer is 180, the efficiency is up to 16%, and the consumption of the single silicon is 3.89w*7g/w=27.23g.When the thickness of silicon wafer is 180, and the weight of silicon wafer is unchanged, the conversion rate of polycrystalline silicon chip is up to 18%, and the chip power is 156*156*0.18/1000=4.38WThis can be pushed: the thickness of the silicon wafer is 180, the weight of the silicon wafer is unchanged, and the conversion rate of the polycrystalline silicon sheet is up to 18%, and the polysilicon consumption per watt is 27.23/4.38=6.2g
Q:What's the connection between silicon wafer and wafer
Just make full use of solar silicon semiconductor optical electrical / thermal conversion characteristics can be said to be the physical characteristics of a simple application, even now, do you use the Internet fiber to your computer to the Internet, there is a light receiver in your side, just because the wavelength of fiber can be much shorter than natural light so more energy so we do not have large silicon wafer as a light receiver are possible, and other materials such as APD in sphalerite semiconductor applications on PIN-diode
Q:What is a silicon wafer cutting edge material?
Because the cutting edge material particles have very sharp edges, and the hardness is far greater than the silicon rod or silicon ingot hardness, so the silicon rod or silicon ingot and steel wire contact area gradually by the cutting edge material particle grinding off, so as to achieve the purpose of cutting.
