ULTRATHIN-BODY SCHOTTKY CONTACT MOSFET

摘要

An ultra thin SOl MOSFET device structure and method of fabrication is presented. The device has a terminal (20) composed o suicide, which terminal is forming a Schottky contact with the channel (30). A plurality of impurities (70) are segregated on the silicide/channel interface (60), and these segregated impurities determine the resistance of the Schottky contact. Such impurity segregation is achieved by a so called silicidation induced impurity segregation process. Silicon substitutional impurities are appropriate for accomplishing such a segregation.
