Q:Polished silicon wafers can be most SEM substrates
There are many kinds of polishing, mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing, fluid polishing, magnetic abrasive polishing!Beijing there throwing a new type of practical technology, science and technology can improve the Liz polishing efficiency and so on.
Q:What's the connection between silicon wafer and wafer
Why is the semiconductor wafer has to be large because he wants to cut into small square chips
Q:What are the difficulties of silicon wafer cutting?
During the cutting process, the wafer quality and rate of finished products played a major role in the grain type, viscosity of silicon carbide powder cutting fluid and particle size, the viscosity of mortar, mortar flow, steel wire speed and wire tension and workpiece feed speed.TTV: and TTV stria stria and is a headache in the wafer processing, from time to time there will be a knife, impossible to guard against. TTV is when the knife into the line, and is easy to appear in the time line bow.
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:What is the cutting fluid for solar wafer cutting?
Solar wafer cuttingThe nine day of the moon is 1 | browse 4555Posted on 2011-03-08 14:06 best answerWire cutting equipment in Sweden, Japan, and domestic equipment;Sweden's MB and HCT devices are a little better;B, HCT, NTC and Ernst & Young wire cutting machine in the silicon wafer cutting silicon wafer cutting fluid and mortar requirementsLabel: cutting machine wire cutting machine silicon solar energyIn recent years, Chinese solar wafer cutting industry booming in Japan in 2008, another solar wafer multi wire cutting machine brand - Ernst & young, also started in the domestic debut, and big cost savings card, that technology has many advantages, more advanced. However, from the point of view of the effect of the use of domestic users, and NTC and MB and HCT in Switzerland, Ernst & Young in China there is a clear case of acclimatized.
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:Why do they make so many transistors on silicon in an integrated circuit
For digital integrated circuits, mainly used for logic operations, and, or, not by the most basic logic constitute a complex logic. Computers are now so complex that they require a lot of transistors.For analog integrated circuits, mainly used to amplify the signal, such as your phone Wifi and other received signals are very weak, you want to use transistor amplifier.
Q:Consult the difference between silicon and battery
From the silicon wafer to the battery piece needs to undergo the process of making wool, and the single crystal silicon wafer is generally made of alkali. Therefore, the appearance of monocrystalline silicon battery is black, and the appearance of polycrystalline silicon sheet is dark blue.
Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
The wax free polishing template can ensure the free rotation of the silicon wafer in the groove of the template,
Q:Solar silicon wafer cutting fluid can burn explosion?
Combustible gas is hydrogen is not polyethylene glycol, but no matter because of ventilation, ventilation, to avoid the closed environment in the case of an open flame on the line
