Patent number: 6797569Abstract: A method for forming a planarized field effect transistor (FET) is disclosed. In an exemplary embodiment of the invention, the method includes defining an active semiconductor region upon a substrate, the active semiconductor region further comprising a pair of mesa regions therein. A source region is defined within a top surface of one of the pair of mesa regions, and a drain region is defined within a top surface of the other of the pair of mesa regions. Then, a gate material is deposited between the pair of mesa regions, and the gate material is planarized to form a gate. Thereby, a top surface of the gate is substantially planar with the source and drain regions.Type: GrantFiled: May 19, 2003Date of Patent: September 28, 2004Assignee: International Business Machines CorporationInventors: David B. Colavito, Nivo Rovedo, Phung T. Nguyen

Patent number: 6764873Abstract: A semiconductor wafer provided with a thermosetting porous insulating film, wherein the insulating film is made porous, cured and polymerized on the wafer. The film is characterized by a very low dielectric constant based on its constituency and porosity, the latter property of which is caused by the inclusion of liquid or supercritical carbon dioxide in the polymeric reaction mixture.Type: GrantFiled: July 18, 2002Date of Patent: July 20, 2004Assignee: International Business Machines CorporationInventors: Habib Hichri, Kelly Malone, Arthur Martin

Patent number: 6642156Abstract: A method for forming an ultra thin gate dielectric for an integrated circuit device is disclosed. In an exemplary embodiment of the invention, the method includes forming an initial nitride layer upon a substrate by rapidly heating the substrate in the presence of an ammonia (NH3) gas, and then re-oxidizing the initial nitride layer by rapidly heating the initial nitride layer in the presence of a nitric oxide (NO) gas, thereby forming an oxynitride layer. The oxynitride layer has a nitrogen concentration therein of at about 1.0×1015 atoms/cm2 to about 6.0×1015 atoms/cm2, and has a thickness which may be controlled within a sub 10 Å range.Type: GrantFiled: August 1, 2001Date of Patent: November 4, 2003Assignee: International Business Machines CorporationInventors: Evgeni Gousev, Atul C. Ajmera, Christopher P. D'Emic

Patent number: 6475893Abstract: A method for preparing a semiconductor material for formation of a silicide layer on selected areas thereupon is disclosed. In an exemplary embodiment of the invention, the method includes removing at least one of a nitride and an oxynitride film from the selected areas, removing metallic particles from the selected areas, removing surface particles from the selected areas, removing organics from the selected areas, and removing an oxide layer from the selected areas.Type: GrantFiled: March 30, 2001Date of Patent: November 5, 2002Assignee: International Business Machines CorporationInventors: Kenneth J. Giewont, Yun Yu Wang, Russell Arndt, Craig Ransom, Judith Coffin, Anthony Domenicucci, Michael MacDonald, Brian E. Johnson

Patent number: 6472740Abstract: A method for forming a multilevel interconnect structure for an integrated circuit is disclosed. In an exemplary embodiment of the invention, the method includes forming a starting structure upon a substrate, the starting structure having a number of metallic conducting lines contained therein. A disk is bonded to the top of said starting structure, the disk including a plurality of mesh openings contained therein. The mesh openings are then filled with an insulative material, thereby forming a cap upon the startig structure, wherein the cap may structurally support additional interconnect layers subsequently formed thereatop.Type: GrantFiled: May 30, 2001Date of Patent: October 29, 2002Assignee: International Business Machines CorporationInventors: Brett H. Engel, Timothy J. Dalton

Patent number: 6333104Abstract: Disclosed herein is an interconnection for electrical connection of two electrical devices. The interconnection comprises a conductive polymer disposed in contact with one or two solderable caps. Together, the solderable cap(s) and the conductive polymer form an interconnection that can be used to connect two electrical devices through the contact pads on the electrical devices. For example, a packaged integrated circuit chip can be connected to a “card” using an array of the interconnections. Since the interconnection has solderable surfaces, the interconnect can be used in place of solder balls in a conventional manufacturing line.Type: GrantFiled: May 30, 2000Date of Patent: December 25, 2001Assignee: International Business Machines CorporationInventors: Charles H. Perry, Mark G. Courtney, Lewis s. Goldmann, Gregory B. Martin
