Q:Hydrogen passivation mechanism of hydrogen fluoride HF in silicon wafer RCA cleaning process
When the concentration of NaOH is higher than 20%W/V, the corrosion rate depends mainly on the temperature of the solution, but not on the actual concentration of the alkali solution.Removal of surface oxide layer on silicon wafer by HF:
Q:Is there anyone who knows how to choose a good glue
But the viscosity is so small. You can use UV or instant glue, curing is relatively fast.
Q:What is a good solar wafer testing equipment?
QCROBOT has been the solar energy as the focus of their products to promote the industry, and has a variety of measurement and control products, for the field of solar energy has launched a variety of measurement and control programs. For example, photovoltaic semiconductor production process control, solar power plant power monitoring system, as well as photovoltaic solar cell volt ampere characteristics test. QCROBOT machine vision system can be used to monitor the shape and size of silicon particles at high temperature. Machine vision can also be used to monitor the quality defects, size measurement, and so on of crystal rods, wafers, panels and components. At present, the QCROBOT vision system and the measurement and control software and hardware platform have been successfully applied to the production and installation process of the solar panel.
Q:Development trend of monocrystalline silicon wafer
LDK LDK is committed to the development of a solar polysilicon materials, ingots and silicon chip R & D, production, sales as one of the world's leading PV enterprises". In the field of polysilicon, polysilicon LDK LDK project to establish a closed-loop circulation system of the most advanced production technology, and all components of waste will be recycled, not only cost savings, but also protect the environment, to solve the biggest bottleneck in polysilicon production technology. After the project is put into production, the cost control will be far beyond the current level of production in China to reach the international advanced level. This will be China's most promising in the environment, scale, cost, quality and other aspects of the overall success of the silicon material project. By 2009, LDK LDK is expected to become the world's leading production capacity of the largest, most technologically advanced, most environmentally friendly process of polysilicon and solar wafer production base. The first practical photovoltaic slicing machine was born in 1980s, it originated from the research and work of Dr. Charles Hauser. Dr. Charles Hauser is the founder of the Swiss HCT slicing system, which is now the predecessor of the application materials company PWS precision silicon wafer processing system division. These machines use a cutting line with a slurry to complete the cutting action. Today, the main structure of the silicon ingot and wafer cutting machine is still based on the original Charles Dr. Hauser machine, but the processing load and cutting speed has been significantly improved.
Q:Why do you use a concentrated sulfuric acid and hydrogen peroxide to wash silicon?
It is very difficult to clean, there are organic residues, this cleaning method is remedial method, belong to after the remedy, the cost is slightly higher
Q:Why integrated circuit electronic devices should be integrated on silicon
A new type of semiconductor device developed in the late 1950s of 60s. It is through oxidation, photolithography, epitaxy, diffusion, evaporation of aluminum and semiconductor manufacturing process, the connecting wire between the required circuit has a certain function of the semiconductor, resistors, capacitors and other components and they are integrated in a small piece of silicon wafer, and then welding electronic devices are encapsulated in a casing. The outer shell of the utility model is provided with a round shell type, a flat type or a double line type. IC technology includes chip manufacturing technology and design technology, mainly in the processing equipment, processing technology, packaging testing, mass production and design innovation ability.
Q:8 inch monocrystalline silicon area?
8 inch silicon wafer, refers to the diameter of 8 inches,1 inches =25.4mm=2.54cm
Q:How many watts can a piece of silicon produce
The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Because silicon is one of the most abundant elements in the earth, the solar battery that destined to enter the mass market (mass market) products, reserves of advantage is to become one of the reasons the main photovoltaic silicon materials.
Q:What does TTV mean in silicon wafer production?
TTV is "total thickness variation" acronym or abbreviation, meaning total thickness variation, total thickness deviation.There is a method to measure the consistency of the thickness of silicon wafer, which is called the total thickness deviation (TTV)
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.
