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:What can be used to adjust its viscosity
If you are a manufacturer of cutting fluid, ask your technical staff
Q:How is the wafer appearance caused? The performance of the chip half white, a class of black! Seek help!
You first check the silicon wafer TTV, as well as doping concentration distribution.
Q:Why do you want to make the wafer bigger?
The cost of the chip is directly related to the area. On the same chip, the more chips can be carved, the lower the price of the chip. Because silicon chips are inevitably produced defects (such as impurities, etc.). The larger the area of a chip, the higher the probability of the collision, and the higher the proportion of the whole wafer. A chip to do one hundred chips, a defect is 1\%. If only do ten, out of a defect is 10\%. An extreme example is the large CCD, professional camera or digital camera with the CCD is 23.7x15.6mm, light by the light area of 370 square millimeters, quickly catch up with the area of the high-end RISC processor
Q:Silicon rod / wafer processing production
At present, more than 98% of the electronic components are all made of monocrystalline silicon. Among them, the CZ method accounts for about 85%, and the other part is the FZ growth method. Monocrystalline silicon grown by the CZ method for the production of low power integrated circuit components. The FZ method is mainly used in the growth of monocrystalline silicon in high power electronic components. The CZ method is more commonly used than the FZ method in the semiconductor industry, mainly because of its high oxygen content provides the advantages of wafer strengthening.
Q:Manufacturers of solar wafers belong to the photovoltaic industry which specific industry classification below
There is no specific classificationPhotovoltaic industry can be divided into the upper and middle reaches of the upper reaches of the main silicon material, silicon products, the middle reaches of the main battery, components, the lower reaches of photovoltaic power generation
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
It is not easy to use high resistance on silicon wafer because of the resistance on silicon wafer,
Q:I grew Ag particles on a silicon wafer, about a few hundred nanometers in size
Alcohol is usually placed inside, with ultrasonic cleaning instrument scattered about, the purpose is to make the particles do not reunite together.
Q:The meaning of various names
Si seed a specific crystal orientation (seeds, usually a small ingot) rod inserted into the molten state under Si, and slowly pull up the crystal and a seed crystal and the same column to be produced by controlling the process variables to pull the speed to control the crystal column the diameter can be cut into a crystal column. The small lot, wafer is produced
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.
