  • Method for constructing semiconductor-on-insulator
    Patent number: 5429955
    Abstract: A method for constructing a semiconductor-on-insulator is provided. A sacrificial layer (12) of a predetermined thickness is first formed on a semiconductor wafer (10) surface. The wafer (10) is then subjected to an ion implantation process to place the ions (16) at predetermined depths below the semiconductor wafer surface. During the implantation process, the sacrificial layer (12) is gradually sputtered away and thereby compensating the gradual outgrowth of the silicon surface due to the volume of the implanted ions (16). A post-implant anneal is performed to allow the ions (16) to react with the semiconductor to form a buried insulating layer (24).
