Patent number: 5229307Abstract: There is disclosed a process for making high performance bipolar and high performance MOS devices on the same integrated circuit die. The process comprises forming isolation islands of epitaxial silicon surrounded by field oxide and forming MOS transistors having polysilicon gates in some islands and forming bipolar transistors having polysilicon emitters in other islands. Insulating spacers are then formed around the edges of the polysilicon electrodes by anisotropically etching a layer of insulation material, usually thermally grown silicon dioxide covered with additional oxide deposited by CVD. A layer of refractory metal, preferably titanium covered with tungsten, is then deposited and heat treated at a temperature high enough to form only titanium disilicide to form silicide over the tops of the polysilicon electrodes and on top of the bases, sources and drains.Type: GrantFiled: December 19, 1990Date of Patent: July 20, 1993Assignee: National Semiconductor CorporationInventors: Madhukar Vora, Gregory N.

Patent number: 4888300Abstract: To completely isolate an island of silicon, a trench is cut into an epitaxial layer to provide access to a differently doped buried layer. While suspending the portion of the epitaxial layer surrounded by the trench by means of an oxide bridge, the underlying region of the buried layer is etched away to form a cavity under the active area. This cavity, as well as the surrounding trench, is then filled with a suitable insulating material to isolate the active island from the substrate.Type: GrantFiled: November 7, 1985Date of Patent: December 19, 1989Assignee: Fairchild Camera and Instrument CorporationInventor: Gregory N.

Patent number: 4722908Abstract: In the fabrication of bipolar transistors by the single poly process, polysilicon sidewalls are formed along portions of a polysilicon layer that functions as a device contact. The sidewalls serve both as dopant sources which determine the width of underlying base and emitter regions, and as contacts to those devices. Since the thickness of the polysilicon sidewalls, and hence the width of the underlying device regions, are precisely controllable through conventional polysilicon deposition techniques, relatively relaxed design rules can be employed while making possible the formation of emitters having widths less than one-half of a micron.Type: GrantFiled: August 28, 1986Date of Patent: February 2, 1988Assignee: Fairchild Semiconductor CorporationInventor: Gregory N.
