Q:What is the price of monocrystalline silicon
The current price of silicon wafer recycling depends on the quality of the silicon wafer.
Q:The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
You connect the line in two holes on the silicon conductive layer in the middle, this is not a resistance capacitance resistance that integrated circuit in the senior middle school physics is not the kind of silicon wafer by resistance capacitance has made but I hope you can understand the function of course this is just the front-end integrated circuit
Q:Seeking for the video: manual insert silicon wafer single crystal insert method
I'll tell you how to find the tab! First bring gloves put water, the water level must be submerged inserted cassette cleaning or oxidation film will not wash clean
Q:The meaning of various names
Crystal column ends can not be cut into available wafer parts can be called the head tail. Preliminary cutting out the wafer, usually can not be used as a rough surface, wafer production, and usually in the subsequent process of polishing, polishing the noun to which. According to the different requirements of wafer fabrication, usually need to rough wafer in doping some impurities, such as P, B and so on, to change its resistance, thus had low resistance, high resistance, heavily doped term coated can be understood as the extension of Epi, according to the specific requirements of the device semiconductor is made of wafer, is usually used in high-end IC and special IC, such as Si on insulator (SOI). In the production process of IC wafer
Q:What is the role of silicon wafer annealing furnace, what specific requirements
I want to be the temperature to more than 1 thousand degrees, and then clean the furnace
Q:What is the specific way to clean the silicon wafer suede concrete steps
LED (Light Emitting Diode), light emitting diode, referred to as LED, is a kind of power can be converted into visible light solid-state semiconductor devices, which can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to a support, one end is a negative electrode, and the other end is connected with the positive electrode of the power supply so that the whole chip is encapsulated by epoxy resin. The semiconductor chip is made up of two parts, one part is the P type semiconductor, in which the hole is dominant, the other end is the N type semiconductor.
Q:How is the silicon chip integrated circuit?
The following procedures: scribing - sintering base - bonding - in - Test - Packaging - aging - testing - printing (laser or screen printing)
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:After the completion of the silicon chip will appear in the shadow of the white spots or what is the situation? How to solve
Check the cleaning agent is uniform, cleaning time is appropriate
Q:Why do you want to make the wafer bigger?
So the price of a light on the CCD. Because the yield is very low. Astronomical telescopes or military reconnaissance equipment used on the larger size of CCD (such as 4, 8 inches or even 12 inches CCD) is simply astronomical. Looking for a piece of silicon wafer that is close to zero defect is probably a vast project. And the speed of the chip is also affected by the area. The larger the area, the greater the span of the wiring, the greater the frequency of interference and signal
