Patent number: 8129262Abstract: Fabrication of an insulated-gate field-effect transistor (110) entails separately introducing three body-material dopants, typically through an opening in a mask, into body material (50) of a semiconductor body so as to reach respective maximum dopant concentrations at three different vertical locations in the body material. A gate electrode (74) is subsequently defined after which a pair of source/drain zones (60 and 62), each having a main portion (60M or 80M) and a more lightly doped lateral extension (60E or 62E), are formed in the semiconductor body. An anneal is performed during or subsequent to introduction of semiconductor dopant that defines the source/drain zones. The body material is typically provided with at least one more heavily doped halo pocket portion (100 and 102) along the source/drain zones. The vertical dopant profile resulting from the body-material dopants alleviates punchthrough and reduces current leakage.Type: GrantFiled: October 27, 2009Date of Patent: March 6, 2012Assignee: National Semiconductor CorporationInventors: Constantin Bulucea, Fu-Cheng Wang, Prasad Chaparala
