LED wafer

The led wafer is key core of led. in fact, the wavelength , bright , input forward voltage of led depends on led wafer.led production process is performed under led wafer. so wafer technology is import for led.

what is led wafer? Now that we had a brief overview of wafer , raw material of water is silicon. water is silicon wafer that it have been used for silicon semiconductor integrated circuit. this wafer shape was regular circle. a single piece of semiconductor material that has been cut from a slice by scribing and breaking. a wafer can be made into a variety of specifications for the electricity circuit (include led module).
