Patent number: 7445960Abstract: A plasma conditioning method of improving the adhesion between an integrated circuit chip, having active and passive surfaces, the active surface polymer-coated and having a plurality of electrical coupling members, and an insulating underfill material. The method comprises the steps of positioning a wafer having a plurality of integrated circuits, including the coupling members, in a vacuum chamber of a plasma apparatus so that the polymer-coated surface faces the plasma source. Next, a plasma is initiated; the ion mean free path is controlled so that the ions reach the wafer surface with predetermined energy. The wafer surface is then exposed to the plasma for a length of time sufficient to roughen the polymer surface, clean the polymer surface from organic contamination and improve the surface affinity to adhesion. The adhesion ability of this surface to organic underfill material is thus enhanced.Type: GrantFiled: June 14, 2007Date of Patent: November 4, 2008Assignee: Texas Instruments IncorporatedInventors: Marvin W. Cowens, Masood Murtuza, Vinu Yamunan, Charles Odegard, Phillip R. Coffman

Publication number: 20040115934Abstract: A method for improving the electrical resistance of contacts on an integrated circuit. The method includes the steps of first exposing the contacts to a solvent, thereby removing organic contaminants; and then exposing the contacts to ion bombardment, thereby removing inorganic contaminants. The step of exposing the contacts to ion bombardment can remove a portion of the contact. The method may also include a step of oxidizing the pad to produce an oxide layer of a predetermined thickness. The ion bombardment can be carried out in a parallel plate etch tool or by using the RIE tool used to carry out a previous etch step. Another embodiment of the invention is a method of improving the resistance of contacts on an integrated circuit including the steps of: exposing the contacts to ion bombardment in the presence of a fluorine and oxygen plasma, thereby removing inorganic contaminants; and exposing the contacts to a solvent, thereby removing organic contaminants.Type: ApplicationFiled: December 13, 2002Publication date: June 17, 2004Inventors: Jerry Broz, Cheryl Hartfield, Elizabeth R.

Patent number: 6514881Abstract: An organically modified dielectric network structure (208) and solid halide-containing material (206) are co-deposited using a chemical vapor deposition process. The solid halide-containing material (206) is then sublimated leaving a porous dielectric (212). An encapsulating layer (210) is formed over the porous dielectric (212) to seal any remaining halide-containing material Within the porous dielectric (212).Type: GrantFiled: April 20, 2001Date of Patent: February 4, 2003Assignee: Texas Instruments IncorporatedInventor: Phillip R.

Patent number: 6315397Abstract: A process for creating and an apparatus employing reentrant (pointing or directed inward) shaped orifices in a semiconductor substrate. A layer of graded dielectric material is deposited on the semiconductor substrate. A masked photoimagable material is deposited upon the graded dielectric material and exposed to electromagnetic energy such that a patterned photoimagable material is created. The patterned photoimagable material is developed to unveil the graded dielectric material which is then anisotropically etched. The bore in the graded dielectric material is then isotropically etched to complete the creation of holes in the substrate.Type: GrantFiled: December 13, 2000Date of Patent: November 13, 2001Assignee: Hewlett-Packard CompanyInventors: Martha Truninger, Phillip R.
