The method includes: providing a first quantity of resin material of epoxy or cyanate ester resins; adding to the first quantity of resin material a second quantity of flexibilizing agent; adding to the first quantity of resin material a third quantity of filler material; blending the resin material. After adding the flexibilizing agent, adding the filler material, and blending the resin material, applying the composition to a gap between a substrate and a semiconductor chip. After applying the composition to the gap, pregelling the composition. After pregelling the composition, substantially curing the composition.Type: GrantFiled: March 19, 2007Date of Patent: January 22, 2008Assignee: International Business Machines CorporationInventor: Konstantinos I.

Patent number: 7304099Abstract: The invention relates to an improved system for inkjet printing which results in images with increased permanence as measured by transfer of color from the image when the image is subjected to mechanical and/or chemical abrasion. The invention provides a fusible material that may be combined with any or all of the color inks used to create the image, or it may be used as a colorless fluid applied pre- or post-printing. The permanence of images produced by the system are comparable to those produced by electrophotography. The invention also relates to a printing apparatus that contains a means for fusing the image using heat applied after the printed substrate is ejected from the printer.Type: GrantFiled: April 25, 2002Date of Patent: December 4, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventor: Makarand P Gore

Patent number: 7304103Abstract: The present invention incorporates new processes for blending derivatized carbon nanotubes into polymer matrices to create new polymer/composite materials. When modified with suitable chemical groups using diazonium chemistry, the nanotubes can be made chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as mechanical strength) to the properties of the composite material as a whole. To achieve this, the derivatized (modified) carbon nanotubes are physically blended with the polymeric material, and/or, if desired, allowed to react at ambient or elevated temperature. These methods can be utilized to append functionalities to the nanotubes that will further covalently bond to the host polymer matrix, or directly between two tubes themselves.Type: GrantFiled: August 1, 2003Date of Patent: December 4, 2007Assignee: William Marsh Rice UniversityInventors: James M. Tour, Jeffrey L. Bahr, Jiping Yang
