The function of green laser pointer as microphone is automatically on-state

Laser annealing: initial laser annealing is to eliminate the damage caused by ion implantation in semiconductor circuit substrate and activate injected impurities. This work is now extended to a wide range, in some cases no longer exists the ion implantation damage, such as the formation of silicide, amorphous material to crystal growth, chemical deposition of polycrystalline formation of large grain polycrystalline. These technologies provides a new method for LSI manufacturing. Can form steep and shallow pn junction, the doping concentration areas higher than ordinary impurities activation method, and form a good connection. The most useful is a cheaper crystal growth in the amorphous materials, crystalline semiconductor manufacturing methods, can be formed with an insulating layer multi-layer crystalline films, and offers the possibility for the development of three-dimensional integrated circuits. The working temperature of the battery of     green laser pointer   is -10℃-+60℃.
Laser annealing technology is a new technology for semiconductor processing, the effect is much better than conventional thermal annealing. Laser annealing, the impurities for the bit rate can reach 98% ~ 99%, allows polysilicon resistivity down to ordinary annealed 1/2 to 1/3, can also greatly improve the integration of integrated circuits, the circuit the interval between the components is reduced to the following 0.5um. Laser Storage: CD-ROMs in two phases, the first stage is the second phase of the laser engraving of the master disc is an impression mold is to suppress the production of user disk. The engraving of the master disc, the information is first recorded with a laser to the photoresist on the high-quality disk-shaped substrate, this process is known as the main recorded. The storage temperature of the battery used by    green laser pointer    is -10℃-+45℃.
Dye recording layer to switch to the inorganic material layer, the inorganic material layer can be converted between crystalline and amorphous, and by pulsed laser heating, variable back and erase the original data can be re-recorded data and information. Laser storage technology is the use of laser to record video, audio, text information and a computer information technology, is one of the supporting technologies of the information age. Laser crossed: With the increasing size of the monocrystalline silicon substrate and ultra large scale integrated chip size gradually decreases, the number of chips of a few inches on the chip manufacturing thousands of tablets in the package before the chip, must be substrates The layout of the chip cut off. The positive pole of the battery of     green laser pointer   will be marked as “+”.
Compared to the ultra-thin diamond wheel cutting, laser marking non-contact cutting, cutting powder and coolant contamination, smooth incision, high precision. Laser scribing technology has become a key technology for the production of integrated circuits, crossed thin, high precision (line width 15 ~ 25um, the groove depth of 5 ~ 200um), processing speed, yield up to 99.5%. Currently, the British quartz Company is used to test the laser scribing techniques to improve the efficiency of solar cells. The night before the quartz was coated with a laser on depicts the grid, in order to increase the electron density and thus the ordinary solar cell conversion efficiency from 12% to 17%. And there is no mark at the negative pole of the battery used by   green laser  .
Laser processing applications in other industries. Laser Rapid Prototyping: Laser rapid prototyping technology integrates laser technology, the latest achievements of the CAD / CAM technology and materials technology, according to the three-dimensional graphics of the computer to design parts of the CAD model, the direct manufacture of the model, manufacturing model of the way on the first floor continue to add material on the basis of the access layer. In contrast, the traditional manufacturing process from a chunk of raw materials, and gradually cut off the unwanted part. Laser rapid prototyping machinery manufacturing process flow and manufacturing technology, a thorough change. Light rapid prototyping can be used to assess the parts form and assembly, but also the reaction part of the functionality. Here will also introduce a kind of   laser pointer   in the bottle shape.
