Title: Treatment device for lowering resistance of semiconductor
Inventor: SENDAI TOSHIAKI
IPC: H01L21/00
Filed: 2001-08-23
Granted: 2002-09-21
Abstract: The invention relates to a treatment device for lowering resistance of a semiconductor, which is used to efficiently lower the electrical resistance of a p-type semiconductor or the driving voltage of a semiconductor element that exerts light emitting/receiving actions. In the invention, an ion plasma type electron beam irradiation equipment (100) generates an electron beam that irradiates over a wide area. The generated electron beam is emitted through the external wall (metallic sheet (108)) of a beam emitting window (107) intercepting outside air. Immediately below the window (107), the p-type semiconductor is arranged on a sample holder (109) in almost parallel with the metallic sheet (108) at an interval of, for example, about 20 mm from the window (107). When the surface of the p-type semiconductor is irradiated with the electron beam by using the equipment (100), the electrical resistance of the semiconductor can be lowered effectively in about three minutes which are extremely shorter than the time required by the conventional electron beam irradiation equipment. The reason is that no physical requirement that strongly restricts the area, etc., of the window (107) exists and the width of the electron beam becomes broader and, accordingly, it becomes unnecessary to repeat scanning many times for a long time.
