Q:Why integrated circuit electronic devices should be integrated on silicon
Another image, that is, the integrated circuit is a combination of some electronic components and wiring, no insulation and insulation as a support. It is achieved by adding bias and other techniques to isolate.And for why it's cheaper to use silicon, it's not because of its semiconductor nature that it uses it. The formation of P and N, a multi hole, a multi electron, and thus the role of different doping. GaAs expensive, but the performance is good, mostly for high-speed circuits and military aspects.
Q:What is a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
One way and two way cutting of silicon wafer is the two way to cut silicon ingot by using solar energy cutting wire.When slicing machine uses solar cutting line to cut silicon ingot,
Q:How to make the photoresist and silicon substrate adhesion better
PR and the same solvent for the HMDS can be better combination, adhesion will be better, will not produce bubble. You can search the TOK OAP material. That's what it's supposed to be
Q:Ultrasonic cleaning cleaning silicon?
1, silicon wafer wafer ultrasonic cleaning function.2, cleaning the wafer production process, pollutants using ultrasonic cleaning machine effectively remove organic matter, wafer surface particles and metal impurities, natural oxide layer and quartz, plastic containers and accessories, the wafer surface damage characteristics. According to different cleaning process, the corresponding cleaning unit is equipped with independent control.
Q:Who is the best silicon chip dryer?
In general, the oil bath furnace heating a little more stable, St. steel technology to give me a more profound sense of the sale, the response time is relatively fast, and the service attitude is better, we can be anxious customers anxious.
Q:How to make monocrystalline silicon solar cells
Wafer inspectionSilicon wafer is the carrier of solar cell, the quality of silicon wafer directly determines the conversion efficiency of solar cell. This procedure is mainly used to measure the technical parameters of silicon wafer on line. These parameters mainly include the surface roughness of the silicon wafer, the lifetime of the minority, the resistivity, the P/N type and the micro crack. The device is divided into four parts: automatic loading and unloading, silicon wafer transmission, system integration part and. The silicon photovoltaic detector on the silicon wafer surface roughness were detected, and the size and appearance of diagonal parameter detection chip; micro crack detection module is used to detect silicon micro cracks; another two detecting module, a [url=] module [/url] online test mainly test wafer resistivity and wafer type, on the other a module for lifetime test wafer. The detection of the diagonal and micro cracks of the silicon wafer is needed before the sub lifetime and resistivity measurement. Wafer inspection equipment can automatic loading and unloading, and substandard products in a fixed position, so as to improve the detection accuracy and efficiency.
Q:Silicon wafer cleaning after the two sides of the upper and lower grille also has a basket of flowers (Bai Yin)
The occurrence of a single crystal is more obvious, other companies have, this would like to find a solution to find a more proficient in the industry to clean up engineers
Q:How to detect the surface finish of photovoltaic silicon wafers, what equipment?
Do you want to check the surface roughness or do you want to clean it? These two are not the same,
Q:Pure curiosity why silicon wafer is round
Journey~woo~'s response: Yeah, why are they made of round bars?...... Sometimes it's a little inconvenient to design the channelRod like the natural shape of production.
Q:What's the connection between silicon wafer and wafer
Just make full use of solar silicon semiconductor optical electrical / thermal conversion characteristics can be said to be the physical characteristics of a simple application, even now, do you use the Internet fiber to your computer to the Internet, there is a light receiver in your side, just because the wavelength of fiber can be much shorter than natural light so more energy so we do not have large silicon wafer as a light receiver are possible, and other materials such as APD in sphalerite semiconductor applications on PIN-diode
