Q:What is the harm of silicon chip into the fingers?
It is also easy to cause other damage, if a small piece of debris along with the flow of blood to the heart, it is very dangerous
Q:What are the reasons for the phenomenon of monocrystalline silicon chip
You say the phenomenon called flower piece, the formation of many factors, the main reason is that contamination, because in the process, the wafer surface after polishing the silicon atom is bond breaking, it is easy to adsorb metal ions and cannot completely by cleaning out.
Q:Pure curiosity why silicon wafer is round
Major manufacturers are trying to expand the cross-sectional area of monocrystalline silicon, not just to cut more wafers per wafer...It's a waste of a lot of material if it's easy.
Q:Is solar silicon wafer often harmful to the body?
Silicon is the main component of Si, is the most widely distributed on the earth, the most abundant storage materials
Q:Why not use N type silicon crystal silicon battery
Can use N type silicon chip, the current SUN POWER battery slice, is the use of N type silicon wafer production, conversion efficiency is very high, but the price is not cheap.At present, most of the domestic manufacturers do not have the production of battery N battery pack, it should be a cost problem.
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 the specific way to clean the silicon wafer suede concrete steps
. Because of the advantages of easy control, low voltage DC drive, rich color after combination, long service life and so on, it is widely used in various engineering, large screen display system. LED can be used as a display, under the control of the computer, display color changes in the video and pictures. LED is a semiconductor capable of converting electrical energy into visible light
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:Why do you choose a silicon chip as a chip?
Silicon is a semiconductor, of course, germanium is also, but silicon is easy to find, you go to the ground to see is the siliconPhysical principles on the complex, the first point of memory knowledge to say it, we generally say how much G, strictly speaking, GB, 1GB=1024MB
Q:Development trend of monocrystalline silicon wafer
In addition, it is conducive to the healthy development of the photovoltaic industry, is conducive to photovoltaic products into millions of households."LDK LDK is a high-tech photovoltaic enterprise focusing on the research and development, production and sales of solar polysilicon material, ingot and polycrystalline silicon wafer. NYSE Listed Companies in 2008 to achieve sales revenue is expected to reach $1 billion 750 million. The photovoltaic business and become the world's first to enter the "GW club". Total orders exceeded 13GW, becoming the world's largest polysilicon suppliers in hand orders.
