Epoxy resin composition, process for providing latency to the composition and a semiconductor device
Patent number: 7723444Abstract: An epoxy resin composition which comprises an epoxy resin (A), a curing agent (B), a curing accelerator (C) and a component retarding curing of the epoxy resin (D) which is at least one component selected from components (a), (b) and (c) represented by general formulae [1], [2] and [3], respectively, a semiconductor device having a semiconductor element encapsulated by using the composition, and a process for providing latency to an epoxy resin composition. The epoxy resin exhibits excellent storage stability, excellent fluidity and curing property during encapsulating by molding and excellent resistance to soldering without forming cleavages or cracks by the soldering treatment at high temperatures in accordance with the lead-free soldering. An epoxy resin composition can be provided with latency by adjusting the amounts of the curing accelerator and the component for retarding curing.Type: GrantFiled: January 20, 2006Date of Patent: May 25, 2010Assignee: Sumitomo Bakelite Co., Ltd.Inventors: Yoshihito Akiyama, Naoki Tomida -
Patent number: 7723445Abstract: By heating, allowing to stand at normal temperature, or irradiating in the presence of a photo-polymerization initiator, a curable resin composition which contains (A) a resin material having a radical polymerizable unsaturated group and an epoxy group, (C) a radical polymerization initiator, (D) an amine compound and/or a mercaptan compound containing one or more of active hydrogen in one molecule, and (E) a compound, which is an adduct in which the (D) amine compound and/or a mercaptan compound, is reacted with the radical polymerizable unsaturated group of the (A) resin material, thereby a cured product can be obtained.Type: GrantFiled: August 4, 2005Date of Patent: May 25, 2010Assignee: Showa Highpolymer Co., Ltd.Inventors: Shintaro Yamauchi, Kazuo Otani

Patent number: 7528189Abstract: The disclosure relates to using metal acrylate compounds such as zinc diacrylate (ZDA), zinc dimethacrylate (ZDMA), among others for curing epoxy functional (and other cross-linking compounds), and to compositions containing such compounds for use in powder coat, film, adhesive, among other applications. ZDA and ZDMA containing compounds can cure the epoxy component of the compositions while being substantially free of conventional curing agents.Type: GrantFiled: October 27, 2004Date of Patent: May 5, 2009Assignee: Blue Goo, LLCInventors: Donald W. Taylor, James W. Freitag, Don K. Howard
