Abstract

The invention discloses an automatic wafer loading and unloading system. The system comprises a storage unit integrated on process equipment, a wafer positioning unit, a wafer disc positioning unit and a wafer disc storage unit. A first loading unit is adopted to transmit wafer discs before and after the process between the wafer disc storage unit and the wafer disc positioning unit, and a secondloading unit is adopted to transmit wafers before and after the process among the wafer disc positioning unit, the wafer positioning unit and a storage unit. According to the system, the efficiency ofthe whole production process can be improved, wafer pollution is avoided, the percent of pass of the wafers placed in the wafer disc is improved, and the rejection rate of the wafers is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control of semiconductor equipment, in particular to an integrated wafer automatic loading and unloading system. Background technique [0002] In the wafer epitaxial PVD (Physical Vapor Deposition) process, it is necessary to place the wafer before deposition on the silicon carbide wafer disk, and after high-temperature deposition in the process equipment, the wafer is removed from the silicon carbide wafer disk out. [0003] At present, it is generally used to manually move the deposited FOUP (front-opening wafer transfer box) with multiple silicon carbide wafers from the PVD equipment to a position, and manually deposit each silicon carbide wafer The final wafer is taken out, and the other wafers before deposition are placed in the silicon carbide wafer tray. [0004] However, the problem of low pass rate occurs during manual operation. Since the wafer transportation is exposed to the ordin...
