The difference between epitaxial wafer and chip is: different properties, different purposes, and different uses. du
1. Different in nature
1. uvc epitaxial wafer: epitaxial wafer refers to a specific single crystal film grown on a substrate substrate heated to an appropriate temperature.
2. Chip: A chip is a solid-state semiconductor device. The entire chip is encapsulated by epoxy resin.
Two, the purpose is different
1. Epitaxial wafer: The purpose of the epitaxial wafer is to add electrodes on the epitaxy to facilitate the sealing and packaging of the product.
2. uvc chip: The purpose of the chip is to convert electrical energy into light energy for lighting.
Three, different uses
1. Epitaxial wafer: The epitaxial wafer is a necessity for the middle and later stages of the LED chip process. Without it, high-brightness semiconductors cannot be made.
2. Chips: Chips are the main materials for making LED lamps, LED screens, and LED backlights.
