Patent number: 7524563Abstract: Provided is a flame retardant adhesive composition including (A) a halogen-free epoxy resin, (B) a thermoplastic resin and/or a synthetic rubber, (C) a curing agent, (D) a phytate compound, and (E) a curing accelerator. Also provided are an adhesive sheet having a layer including the above composition, and a protective layer for covering the layer including the composition; a coverlay film having an electrically insulating film, and a layer including the above composition provided on top of the film; and a flexible copper-clad laminate having an electrically insulating film, a layer including the above composition provided on top of the film, and copper foil. Further provided are a process for producing the adhesive sheet, a process for producing the coverlay film, and a process for producing the flexible copper-clad laminate. The halogen-free adhesive composition yields a cured product, on curing, that exhibits excellent flame retardancy and electrical characteristics (anti-migration properties).Type: GrantFiled: April 12, 2006Date of Patent: April 28, 2009Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Toru Nakanishi, Kazunori Kondo, Shigehiro Hoshida, Tadashi Amano

Patent number: 7504150Abstract: The present invention relates generally to polymer composites having dispersed therein both useful spinel crystal fillers and ferroelectric (and/or paraelectric) fillers wherein the composite is both light activatable and can be used as a planar capacitor material. The light activation is typically employed via a laser beam (or other light emitting device) where the material has a pattern formed thereon. Electrodes are typically formed on the material's surface after patterning is complete via electroless metal plating. These composite polymers can be used as planar capacitors embedded in printed wiring boards or in integrated circuit packages.Type: GrantFiled: June 15, 2005Date of Patent: March 17, 2009Assignee: E.I.
