发明名称 Method to make a SOI wafer for IC manufacturing
摘要 A method to eliminate the sharp edge problem in the bonded wafer technique of the SOI technology is achieved by employing a different dimension of the front surface between the bonding wafer and the holding substrate. A thin film layer with a predetermined thickness is formed to planarize the edge of the finished semiconductor film when the fabrication of the SOI wafer is completed.
