Patent number: 6893523Abstract: A method and resulting electronic package in which a heat sink is secured to the package's dielectric material (e.g., overmold). The surface of the dielectric is roughened (e.g., using an abrasive paper or pad) to enhance the subsequent dielectric-heat sink bond in which an adhesive is used. The dielectric material's roughened external surface(s), typically containing silicone material (e.g., silicone residue) which is an inherent by-product of many dielectric materials of the type used in such packaging, is (are) able to still be securely attached to the heat sink, despite the presence of said silicone. In another embodiment, the roughened surface enhances the marking of dielectric material of this type (e.g., using ink).Type: GrantFiled: February 28, 2002Date of Patent: May 17, 2005Assignee: International Business Machines CorporationInventors: Michael Gaynes, William R.

Patent number: 6875303Abstract: The invention is a process for bonding glass to a substrate without the need to prime the surface of the substrate. The process comprises, first, treating the surface of the substrate with air plasma, applying to the surface of the substrate or to the surface of the glass an adhesive capable of bonding to the treated substrate and glass, and contacting the glass and the substrate with the adhesive disposed between the substrate and the glass, and allowing the adhesive to cure. Preferably the substrate is coated with a coating. Preferred adhesives are polyurethane or silane functional elastomeric adhesives. The process of the invention allows bonding of glass to a substrate without the need to use a primer on the substrate prior to application of the adhesive. The process is especially effective in facilitating the bonding of glass to coated substrates, especially substrates coated with acid resistant coatings such as PPG's carbamate coating or DuPont's Gen III, IV and VI coatings.Type: GrantFiled: November 26, 2002Date of Patent: April 5, 2005Assignee: Dow Global Technologies Inc.Inventors: Andon Samurkas, Ziyan Wu, Sean C.

Patent number: 6866741Abstract: A method for joining large area semiconductor substrates, a liquid thermoset polymer. Two large area substrates, such as wafers or circuit boards (e.g., rigid or flexible), can be joined together by dispensing a liquid polymer inwardly from the edges of the semiconductor substrates. The substrates can then be pressed together so that the liquid thermoset flows in an outwardly direction ward the edges of the semiconductor substrates. Conducting surfaces on the first and second substrates may contact each other after pressing the liquid thermoset polymer. The liquid thermoset polymer in the formed structure may then be cured to a hardened state. The liquid thermoset polymer preferable has a low viscosity, low levels of ionic contaminants, good adhesion to the substrates, low moisture absorbing properties and favorable thermal expansion properties.Type: GrantFiled: January 8, 2001Date of Patent: March 15, 2005Assignee: Fujitsu LimitedInventors: Albert W.
