Q:Why do you want to make the wafer bigger?
Because each layer is insulated by silicon dioxide, it is equivalent to a capacitor structure. The larger the span, the greater the capacity of the wiring. The higher the frequency, the more serious side effects such as the integral effect of the long distance transmission. Basically thought GHz must use the following line width.18 technology. Chip size also affects power consumption. With the same mask and the same operating frequency, the smaller the line width, the smaller the voltage. The power consumption is proportional to the square of the voltage. Want to pursue low power you have to honestly narrow the line width. The semiconductor industry in the world are going to kill red eye, if we do not have shortcut yiwofeng to dive in.
Q:The higher the resistivity of silicon wafers, the better?!!
Low resistivity is helpful to improve the opening pressure, high resistivity and help to improve the short-circuit current, the best match between the two is about 1 -3! Own understanding!
Q:How to calculate the conversion efficiency of monocrystalline silicon
The algorithm is as follows:Solar cell efficiency = (open circuit voltage * short-circuit voltage * fill factor) / (battery area * light amplitude) *100%Light intensity - AM1.5 as the standard, that is 1000W/m2
Q:Why do they make so many transistors on silicon in an integrated circuit
This means that you do not understand the meaning of integrated circuitsI suggest you go online to see what is integrated circuit
Q:The significance of silicon wafer heat treatment
The significance of silicon wafer heat treatmentHeat treatment temperature requirements: 650 + 5 c;The purpose of heat treatment is to restore the true resistivity of Czochralski silicon wafers;
Q:How to extract silicon from silicon wafers
Annealing: double position hot oxidation furnace after nitrogen purging, infrared heating to 300~500 DEG C, silicon wafer surface and oxygen react, so that the surface of silicon dioxide protection layer.
Q:What is a silicon wafer
Is usually used in high-end IC and special IC, such as Si on insulator (SOI) wafer. In the production process of IC, need some wafer to test the status of the production process, such as the level of particle, the etching rate, defect rate and so on, these are often called wafer control chip, the control plate is also used with normal production batch process together to test the quality condition of a process, such as the CVD film thickness. In the production equipment maintenance or repair, immediately production batch of wafer, easy to cause the scrap, and usually use some very low cost wafer to run the process to determine the quality of maintenance or repair work, which is usually called wafer dummy wafer, of course, sometimes dummy wafer also can be used in the normal production process, such as machine must wafer to process a number of problems with dummy wafer complement, and some machines must be in the process of a certain number of wafer A form of dummy run, otherwise the process can not guarantee the quality and so on many wafer and so on can be called dummy. block basically can be regarded as a kind of.Dummy wafer dummy, wafer control chip, a guard sheet usually can be recycled.
Q:Why integrated circuit electronic devices should be integrated on silicon
Another image, that is, the integrated circuit is a combination of some electronic components and wiring, no insulation and insulation as a support. It is achieved by adding bias and other techniques to isolate.And for why it's cheaper to use silicon, it's not because of its semiconductor nature that it uses it. The formation of P and N, a multi hole, a multi electron, and thus the role of different doping. GaAs expensive, but the performance is good, mostly for high-speed circuits and military aspects.
Q:The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
You can look at the aspects of the integrated circuit manufacturing process, integrated circuit design belongs to the back end of these of course, this is not considered in the field of integrated circuit design
Q:What is a silicon wafer cutting edge material?
Online cutting process, the cutting fluid (usually polyethylene glycol) and cutting edge material sand spray with the fall in thin steel wire by thin steel wire net, high speed, make the mortar in cutting edge material and pressed online silicon rod or a silicon ingot surface high speed grinding,
