Abstract
Provided are a method for machining a device and the device. The method for machining a device includes die bonding, primary dicing, filling by a baffle wall material, grinding and secondary dicing. In the step of grinding machining, a semi-finished product is placed on a platform surface of a grinding and fixing platform, a grinding working end of a grinding device is controlled to operate, and with the platform surface of the grinding and fixing platform as a height reference, the grinding working end grinds from above the semi-finished product toward the grinding and fixing platform and operates to a preset height. Through the special machining process, the probability of the appearance of white glue on a top surface of the device is reduced, which is conducive to ensuring a production yield of the device.
