    摘要: A semiconductor fabrication process includes forming a gate electrode (112) overlying a gate dielectric (114) overlying a semiconductor substrate (104) of a wafer (101) and a liner dielectric layer (116) including vertical portions (118) adjacent sidewalls of the gate electrode and horizontal portions (117) overlying an upper surface of the semiconductor substrate (104). A spacer (108) is formed adjacent a vertical portion (118) and overlying a horizontal portion (117) of the liner dielectric layer (116). After forming the spacer (108), exposed portions of the liner dielectric layer (116) are removed to form a liner dielectric structure (126) covered by the extension spacer (108). The extension spacer (108) is then etched back to expose or uncover extremities of the liner dielectric structure (126). Prior to etching back the spacer (108), a metal (130) may be sputtered deposited over the wafer (101) preparatory to forming a silicide (134). After the etch back the wafer (101) may be dipped in piranha solution and cleaned with an RF sputter (140) of argon.

    摘要: Metal-oxide-semiconductor (MOS) transistors with n-type source/drain regions also having germanium-doped regions in or near the source/drains. The presence of germanium near or at the location of phosphorus in graded source drains (GSDs), lightly doped drains (LDDs) and double diffused drains (DDDs) gives a better profile of the drain region with a reduced junction depth than that obtainable with phosphorus or particularly phosphorus and arsenic together. Good grading of the drain junction to avoid hot carrier instability or hot carrier injection problems is obtained along with shallow source junctions, which minimizes lateral dopant diffusion and decreases the distance between n.sup.- and n.sup.+ regions in GSDs and LDDs.

    摘要: A technique for suppressing hillock growth in metal films on integrated circuits through multiple thermal cycles by argon implantation. Although it was known that ion implantation of many species such as arsenic suppressed the growth of hillocks in metal films through one thermal cycle, it was discovered that only one of the proposed ions, argon, would suppress hillock formation for multiple subsequent thermal cycles. For the other species, hillock formation would reoccur after multiple cycles. This characteristic is important for double layer metal (DLM) processes to prevent interlayer shorting.

    摘要: An improved process is disclosed for forming the field oxide which provides isolation between adjacent devices in an integrated circuit. In one embodiment of the invention the improvement includes implanting halogen ions, and preferably chlorine ions, into the selected regions of a semiconductor substrate where field oxide is to be formed. The halogen ions are implanted before the field oxide is thermally grown and result in a localized enhancement of the oxide growth rate in the vertical direction compared to the lateral direction. For a given oxidation cycle, the halogen implant results in the growth of a thicker oxide with minimum lateral encroachment.

    摘要: A process is disclosed for fabricating a semiconductor device which includes a trench formed at the surface of the device substrate. The surface of the device substrate is oxidized and the oxide is patterned to form an opening which exposes a portion of the underlying surface. Ions are implanted through the opening and into the surface to form a damaged surface region which is coincident with the opening and extends under the edge of the oxide. A trench is etched by reactive ion etching using the opening in the oxide as an etch mask. The substrate, including the walls of the trench and the ion implant damaged surface portion under the edge of the oxide, is thermally oxidized. The oxidation rate is enhanced by the damage and causes a thicker oxide to grow in the damaged region which forms a collar around the intersection of the trench with the surface. Upon removing the oxide, the intersection of the trench with the surface is characterized by a rounded corner caused by the enhanced oxidation in that location during the oxidation.

    摘要: A process is disclosed for controlling the surface doping of two regions of a semiconductor device and more specifically for using such control to achieve the necessary field doping in a CMOS device structure. In accordance with one embodiment of the invention a silicon substrate is provided which has first and second regions of opposite conductivity type. A uniform doping such as by ion implantation is provided into each of the conductivity regions. The two regions or portions thereof are then simultaneously differently oxidized to cause a differential segregation of the dopant into the thermally grown oxide. The differential oxide growth can be achieved by selectively implanting halogen ions into the wafer surface prior to the thermal oxidation.
