In-line F3 blue hair blue lamp bead LED light strip What is the manufacturing process of LED chips? 　　LED chip manufacturing is mainly to manufacture effective and reliable low-ohm contact electrodes, and can meet the minimum voltage drop between the contactable materials and provide a pressure pad for the bonding wire, while emitting as much light as possible Light Emitting Diode In-line. The film transition process generally uses a vacuum evaporation method, which mainly uses resistance heating or electron beam bombardment heating to melt the material under a high vacuum of 1.33×10? 4Pa, and becomes a metal vapor deposited on the surface of the semiconductor material under low pressure. The commonly used P-type contact metals include alloys such as AuBe and AuZn, and AuGeNi alloy is often used as the contact metal on the N surface. The alloy layer formed after coating also needs to expose as much of the light-emitting area as possible through a photolithography process, so t…
