Patent number: 7223480Abstract: The present invention relates to a metal laminate which is broadly used for a flexible wiring board or the like and an etching method therefor. In particular, the present invention relates to a metal laminate which includes a layer obtained by laminating a metal layer and an insulating layer, where the insulating layer is subjected to an etching process, wherein, in a surface of the metal layer which is positioned so as to come in contact with the insulating layer, respective concentrations of main metal element and oxygen element constituting the metal layer are measured from the surface of the metal layer towards inside of the metal layer in a time-elapsing manner according to AES (Auger electron spectroscopy) and a value of the thickness of a metal oxide film of the surface of the metal layer measured at a time when atomic concentrations of the main metal element and the oxygen element constituting the metal layer become equal to each other is in a range of at least 0 ? to less than 50 ?.Type: GrantFiled: July 28, 2003Date of Patent: May 29, 2007Assignee: Mitsui Chemicals, Inc.Inventors: Koji Hirota, Masanao Kobayashi, Minehiro Mori, Naoki Nakazawa

Publication number: 20050165196Abstract: The adhesive resin of the invention comprises a polyimide resin obtained by reacting a diamine component containing the compound (1) as an essential component with a tetracarboxylic dianhydride component. The diamine component contains a silicone diamine having a specific structure and/or the tetracarboxylic dianhydride component contains a silicone acid dianhydride having a specific structure. Film adhesives made by using the adhesive resin preferably together with a thermosetting resin, and, if necessary, an inorganic filler are excellent in low-temperature adhesion, resistance to moisture absorption, heat resistance, and workability in adhesive adhering and are favorably usable as semiconductor-mounting materials for adhering semiconductor elements to substrates.Type: ApplicationFiled: May 29, 2003Publication date: July 28, 2005Inventors: Jin Kinoshita, Moritsugu Morita, Minehiro Mori, Yoichi Kodama
