Q:Why do monocrystalline silicon chamfer? Polysilicon film?
Chamfering is for this purpose, grinding and polishing are also for this purpose. As a single crystal practitioners, it is recommended that you take a look at the processing technology of silicon single crystal wafer > this book, written by Zhang Juezong, more comprehensive
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:How many times is the resistance of the same size silicon
How many times is the resistance of the same size silicon
Q:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
As for the power, according to the W=UI formula can be obtained, since a single voltage is fixed, the resulting current size determines the power of a battery, the current per tablet produced is not fixed, with the conversion rate of the conversion rate, high current is large, the reverse is small; the same the power conversion rate is high, the area is small
Q:The metal in the silicon wafer
The properties of silicon have excellent electrical properties. The band gap is moderate, and is 1.21 ev. Higher carrier mobility, the electron mobility is 1350 cm / sec / V /, hole mobility is 480 cm / sec / v. The resistivity at room temperature (300K) up to 2.3 x 10 - Europe - cm wide, doped resistivity can be controlled in 10 - to 10 - Europe - cm, can meet the needs of manufacturing various devices. The minority carrier lifetime of the single crystal silicon is longer than that in a few tens of microseconds to 1 milliseconds. Larger thermal conductivity. The chemical property is stable, and is easy to form a stable thermal oxidation film. It can be used to realize the surface passivation and protection of the PN junction in the fabrication of planar silicon devices, and the metal oxide semiconductor structure can be formed to produce MOS field effect transistors and integrated circuits. The properties of the PN junction has good characteristics, so that the silicon device has the advantages of high pressure, the reverse leakage current, high efficiency, long service life, good reliability, good heat conduction, and in the 200 - high temperature operation etc..
Q:Why can silicon chips store information? Even if it is a miniature circuit, unplug the power will be no electricity
So when you need to save the power. As you say the iron, can be used to save the information - the tape is the use of micro magnets to record
Q:P type and N type monocrystalline silicon chip difference?
The doping of boron in monocrystalline silicon is P, the more boron doped, the more holes can be replaced by silicon. The stronger the electrical conductivity, the lower the resistivity
Q:The benefits of silicon chip
(a) hot rolled silicon steel sheet for electrical purposes (GB5212-85)The hot rolled silicon steel sheet used for electrical engineering is made of soft magnetic alloy with low carbon content and low carbon steel, which is rolled into a sheet with thickness less than 1mm. Hot rolled silicon steel sheets for electrical purposes.Hot rolled silicon steel sheet according to the combination of silicon content can be divided into low silicon (Si = 2.8%) and high (Si = 4.8%) of silicon steel sheet two.(two) cold rolled silicon steel sheet for electrical purposes (GB2521-88)The silicon steel 0.8%-4.8% containing silicon steel is used as the material, which is formed by cold rolling.Two kinds of steel strip with grain orientation and grain orientation for cold rolled silicon steel sheet. The cold rolled electrical steel strip has the advantages of smooth surface, uniform thickness, high coefficient of lamination and good impact resistance, and has higher magnetic susceptibility and lower iron loss than the hot rolled steel strip. Instead of producing hot rolled motor or transformer with cold strip, its weight and volume can be reduced by 0%-25%. If the cold rolled oriented belt, better performance, use it instead of hot-rolled or cold-rolled low grade, can reduce the power consumption of the transformer 45%-50% transformer, and more reliable performance.For the manufacture of motors and transformers. In general, the grain oriented cold rolled strip is used as the state of the motor or welding transformer, and the grain oriented cold-rolled strip is used as the core of the power transformer, pulse transformer and magnetic amplifier.Plate size: thickness of 0.35, 0.50 and 0.65mm, the width is 800-1000mm, the length is less than or equal to 2.0m.
Q:Why integrated circuit electronic devices should be integrated on silicon
First of all, the general circuit of the insulator, just a carrier, it plays the role of support and insulation. As for the integrated circuit, the bottom layer is called the substrate (generally P type semiconductor), is to participate in the work of integrated circuits. CMOS process, so the Nmos substrate are connected together, are the same substrate.
Q:The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
You connect the line in two holes on the silicon conductive layer in the middle, this is not a resistance capacitance resistance that integrated circuit in the senior middle school physics is not the kind of silicon wafer by resistance capacitance has made but I hope you can understand the function of course this is just the front-end integrated circuit
