Patent number: 6190834Abstract: The present invention provides a photosensitive resin composition capable of forming an insulating film, which is superior in both a roughening property and an adhesiveness, and a via-hole, which is highly reliable in connection, and a multilayer printed circuit board. The present invention provides a photosensitive resin composition containing a first resin, which is an epoxy resin, and a second resin having a N-substituted carbamic acid ester atomic group and a radical polymeric unsaturated bond in its side chain. The second resin is desirably an oligomer having a repeating unit expressed by the following general formula (chem. 1) or (chem. 3) by 3-10 units. Where, X is H or CH3, Y and Z is H or an alkyl group of carbon number 1-4, n is 0 or 1, a part of R1 is an atomic group expressed by the following general formula (chem. 2), the residual R1 is a hydroxyl group, and R2 is an alkylene group of carbon number 1-4.Type: GrantFiled: May 6, 1998Date of Patent: February 20, 2001Assignees: Hitachi, Ltd., Hitachi Chemical Company, Ltd.Inventors: Masatoshi Narahara, Mineo Kawamoto, Tokihito Suwa, Masao Suzuki, Satoru Amou, Akio Takahashi, Hiroyuki Fukai, Mitsuo Yokota, Shiro Kobayashi, Masashi Miyazaki

Patent number: 5955512Abstract: A pressure sensitive adhesive composition is disclosed which comprises an acrylic copolymer (A), an energy beam polymerizable urethane acrylate oligomer (B) and an energy beam polymerizable compound having one acryloyl group or methacryloyl group in each molecule thereof (C). This composition is preferred to further contain a plasticizer (D), a crosslinking agent (E) and/or a photopolymerization initiator (F) according to necessity. The pressure sensitive adhesive composition has satisfactory pressure sensitive adherence and initial adhesion before the irradiation with energy beam and the adhesive strength thereof is sharply reduced with maintaining the rubber elasticity after the irradiation with energy beam. Further, the pressure sensitive adhesive composition ensures excellent chip alignability in the expanding step subsequent to dicing.Type: GrantFiled: April 24, 1997Date of Patent: September 21, 1999Assignee: Lintec CorporationInventors: Hideki Numazawa, Yoshihisa Mineura
