A fast annealing furnace is a process used to manufacture semiconductor devices that involves heating multiple semiconductor wafers to affect their electrical properties. Heat treatment is designed for different effects. The wafer can be heated to activate dopants, the film can be converted to a film or wafer substrate interface, the film can be densely deposited, the state of the growing film can be changed, injected damage can be repaired, the dopant can be moved or transferred from one film to another, or the dopant can be moved from the film to the wafer substrate.
So what are the types of rapid annealing furnaces?
First, aluminum alloy rapid annealing furnace.
It is mainly used for heat treatment and soaking annealing of aluminum alloy and aluminum plate.
Aluminum alloy rapid annealing furnace is composed of trolley furnace body, circulation system, diversion equipment, heating element, charging trolley, furnace door lifting mechanism and electrical control system.
Second, well type vacuum rapid annealing furnace.
Suitable for annealing round wire and steel strip. Vacuum heating annealing, no nitriding and no decarburization, so that the workpiece after annealing to keep bright. Vacuum rapid annealing furnace is mainly composed of furnace body, furnace lining, vacuum pump, circulating fan and electrical control system.
Three, multi-tube stainless steel wire bright rapid annealing furnace.
It consists of a heating furnace, a cooler, a winding mechanism and an electronic control system.
It is mainly used for bright annealing of stainless steel wire, copper wire, iron wire, etc.
Four, well type rapid annealing furnace.
Suitable for round wire and stainless steel wire, annealing before drawing, less oxidation, no decarbonization, so that the workpiece after annealing to keep neat. Features: Can be configured with multiple furnaces, multi-station operation can save human resources, improve production efficiency, save energy, reduce production costs.
5, the trolley type rapid annealing furnace is mainly used for normalizing and annealing heat treatment of copper bars, steel castings, auto parts, rolls, steel balls, metal structural parts and welds. The trolley type rapid annealing furnace is mainly composed of door lifting and sealing equipment, furnace car, furnace car transmission mechanism, electric heating equipment and temperature control system. It can be used on level ground without foundation installation.
Six, cover type rapid annealing furnace.
The equipment can be widely used in non-ferrous copper, aluminum alloy, ferrous metal, carbon steel, silicon steel, alloy steel and other coil, coil, wire annealing. There is no nitriding and decarburization, so that the workpiece can remain neat after annealing. The fast annealing furnace has the advantages of high production efficiency, good product quality, low energy consumption, no pollution, automatic operation, safety and reliability. The furnace is composed of a heating cover, two furnaces, a valve frame and an electrical control system.
