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: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:Why silicon wafers are made in watts!
Crystalline silicon photovoltaic cells have two types of monocrystalline silicon and polycrystalline silicon, with P (or n) silicon substrate, through the formation of phosphorus (or boron) diffusion Pn formation, production technology is mature, is the leading product in the photovoltaic market. The buried layer electrode, surface passivation, enhanced light trapping, dense grid technology, optimization of back electrode and contact electrode technology, improve the collection efficiency of carrier materials, optimization of anti elbow membrane, concave convex surface, high reflective back electrode, the photoelectric conversion efficiency is greatly improved. Silicon photocell area is limited, the larger the phi 10 to 20cm wafer, the annual production capacity of 46MW/a. At present, the main task is to continue to expand the scale of the industry, the development of ribbon silicon photovoltaic technology, improve material utilization. Internationally recognized as the highest efficiency under AM1.5 conditions of 24%, the space with high quality efficiency in the AMO condition is about 13.5 - 18% of the ground with a large number of production in the AM1 conditions in the more than 11 - 18%. It can reduce the cost, but the efficiency is lower, which is made by the method of directional solidification. Optimization of the silver electrode and aluminum paste screen printing, grinding and polishing process, do everything possible to further reduce costs, improve efficiency, the maximum conversion efficiency of polycrystalline silicon photovoltaic cells up to 18.6%.
Q:How much harm silicon on the human body
But if you want to use the laser machine, then pay attention to the laser source.
Q:What can be used to adjust its viscosity
If you are a manufacturer of cutting fluid, ask your technical staff
Q:What to do with silicon. What is the relationship between the semiconductor and the PCB board
However, in order to manufacture semiconductor components and integrated circuits (IC). Pure silicon wafers have to be created and then used in a variety of processes, such as etching, doping, etc., to make conductive semiconductor circuits on silicon wafers. This process can achieve the level of precision represents the level of semiconductor manufacturing processes, such as the computer's CPU is the number of microns with the manufacture of technology. Because the process is more precise, in the same size of silicon, can make a number of more circuits, that is to achieve a higher degree of integration. At the same time, because the distance between the circuit is small, the length of the wire is short, the required working voltage is lower, the power consumption can be reduced, and the operating speed can be increased.
Q:How to make the photoresist and silicon substrate adhesion better
By the way, if there is a reflection of the bottom, then you need to coat a layer of BARC, and then at coat PR.Hope can help you.
Q:How to do on the silicon wafer
1, observation and analysisFirst check the pollution level of the battery plate to be cleaned before cleaning. If it is mild pollution - no particles, only dust. It is recommended that we do the washing and scrubbing alone. This will not only save, save manpower and material resources, but also to extend the surface of the battery board to maintain a certain degree of brightness. Increase its life!
Q:Monocrystalline silicon processing technology
Most photovoltaic equipment suppliers buy chip wire. They generally grow silicon ingots or silicon blocks and process silicon materials into wafers, which are eventually sold to photovoltaic cell manufacturers for the production of batteries. The installed capacity of the industry's most successful application of B5 wire materials company HCT system more than 500 units, is a benchmark in the field of photovoltaic chip products.conclusionIn the field of photovoltaic technology, wire reduces wafer thickness and reduce the material loss in the cutting process, thereby reducing the power consumption of the solar silicon materials. (therefore, wire saw technology to reduce the cost per watt of solar energy and eventually to achieve grid parity has played a crucial role. The latest and most advanced wire technology brings a lot of innovation, improve the productivity and the thinner silicon wafers to reduce the consumption of silicon materials.
Q:What's the difference between a silicon wafer and a battery?
Silicon wafers are cut into pieces by wire cutting!The battery pack is a silicon wafer through the surface flocking, diffusion of PN junction, and then PECVD coating
