Q:How is the silicon chip integrated circuit?
Based on TTL series integrated circuit as an example, from silicon to process integrated circuit: cut off from a monocrystalline silicon chip, polished - polishing - oxidation - lithography - diffusion - epitaxial buried layer - oxidation - oxidation - diffusion - isolation lithography lithography - base diffusion - oxidation lithography - emitter diffusion vacuum aluminizing - sintering (ohmic contact lithography) - at the initial test procedure is done.
Q:The metal in the silicon wafer
By 1960, the scale of industrial production had been in this way. Silicon rectifier and thyristor has prompted the silicon material production jumped in the first semiconductor material. With the development of silicon epitaxial single crystal technology and silicon planar technology in 60s, it not only makes silicon transistor manufacturing technology mature, but also promotes the rapid development of integrated circuits. In early 80s the world's polysilicon production reached 2500 tons. Silicon is one of the promising materials for solar cells. The technology of producing solar cells with polycrystalline silicon has been mature; amorphous silicon films have been developed rapidly. Chemical element silicon. Electrically active impurities phosphorus and boron should be less than 0.4ppb and 0.1ppb in qualified semiconductor and polysilicon. A certain amount of electroactive impurities should be added to the single crystal to obtain the required conductivity and resistivity. Heavy metals such as copper, gold, iron and nonmetal are very harmful impurities. The carbon content in silicon is higher than that of 1ppm. When the carbon content is over 3ppm, the harmful effect is more significant. Oxygen content in silicon is very high. Oxygen is both beneficial and harmful. The content of oxygen in Czochralski silicon is within the range of 5 to 40ppm, and the oxygen content of the fused silica can be less than 1ppm.
Q:The production of silicon units do front-line production workers harmful to the body
Please also note: as long as it is in the production of factory work, there are more or less some occupation hazards, such as peripheral equipment operation noise, dust production, if the production site without the necessary protective equipment is also possible occupation disease.So my answer is only from the perspective of occupational protection.
Q:The significance of silicon wafer heat treatment
The significance of silicon wafer heat treatmentHeat treatment temperature requirements: 650 + 5 c;The purpose of heat treatment is to restore the true resistivity of Czochralski silicon wafers;
Q:What is a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
Bidirectional cutting line cutting, (1) from the line wheel line network and enter the waste wire wheel (2) after a certain length reverse line wheel released by the waste reverse into the line network into the line wheel (3) repeat from the line wheel into the wire and into the process of waste wire wheelBut the length of 1 is greater than 2
Q:Wafer size6 inches and 8 inches only refers to the diameter of monocrystalline silicon?
Refers to the diagonal length of the silicon waferBut you asked the wrong question, the wafer is divided into monocrystalline silicon and polycrystalline silicon wafer, you say is a square of silicon polysilicon film of silicon wafer, you ask in the four corner is a circular arc shape, so you should also count the length of the diagonal right. If not to shape the polysilicon film solution you can search the Internet search look.
Q:There is a micro structure on the side of the silicon wafer
For solar cells destined to enter the market market (mass) products, the advantages of reserves is also one of the main reasons for the silicon photovoltaic materials.
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
In some places, the resistance of the epitaxial layer is adopted, and the resistance is N type, which has a lot of inconvenience in the circuit, and the numerical value is also very difficult to do
Q:Why can silicon chips store information? Even if it is a miniature circuit, unplug the power will be no electricity
Storage of information is not a silicon chip, called memory, which is a transistor electronic components, called the silicon chip is made of silicon crystals directly on the transistor array,
Q:Geometric parameters and testing of silicon wafer
Wafer inspection the main test items are: side, diagonal, chamfer, thickness, TTV, line, chipping, cracks, warping, oil, resistivity, lifetime.
