The essence of the process
Laser annealing, unlike the traditional one, produces heating of the metal by heat generated by a laser installation. The process takes place very quickly and usually in the open air. The basic structure of the laser annealing equipment is a set of devices that first scan the surface of the material and then produce the necessary focusing of the laser beam using a condensing lens.
Laser annealing is an obligatory step in the production of liquid crystals. A silicon film on a substrate made of a liquid crystal panel is irradiated by a laser to heat it at a low temperature and converted to a liquid crystal of polysilicon (p-Si).
Previously, p-Si formed at a high temperature in the furnace. However, at the same time, there were problems — the appearance of a substrate exposed to heat and a high duration of the process. Since low-temperature heating by laser annealing quickly heats the surface of the material and allows it to cool down, problems caused by the duration of setting the high temperature in the furnace are solved.
Urgency of application
Laser annealing is used primarily in the semiconductor industry, where the conventional transistor drive section is usually formed by a thin layer of amorphous silicon (a-Si, a noncrystalline semiconductor) controlled by the electron velocity (mobility characteristic) of about 0.5.

Advantages of laser annealing
Modern laser annealing technologies based on the use of solid-state lasers make it possible to perform an especially accurate annealing using several lenses. This ensures the efficient use of laser energy, since annealing is performed inside the transistor.
Laser annealing refers to local heating, which changes the color of the heated material as a function of the heat temperature. The annealing color can vary between yellow, red and green, due to the temperature on the surface of the product. The thermal laser beam makes it possible to create surface marks that are used in the storage of medical and veterinary objects. Laser annealing leaves the surface as clean as before processing.
