Publication number: 20080314627Abstract: There are provided an electronic component in which two substrates are bonded to each other with a large bonding force and a method for manufacturing electronic components in which two substrates can be bonded to each other with a large bonding force and in which the substrates are not likely to be bent and broken. In an embodiment, a plurality of first connection portions 30 is formed on a first substrate 22, and in addition, a plurality of IDT electrodes 26 and a plurality of second connection portions 32 are formed on a second substrate 24. The first connection portions 30 are engaged in concave parts of the second connection portions 32, so that temporary bonding is performed. Between adjacent first connection portions 30, only the first substrate is cut. By heat application, laser irradiation, pressure application, ultrasonic application, or the like, the first connection portions 30 and the second connection portions 32 are finally bonded to each other.Type: ApplicationFiled: September 8, 2008Publication date: December 25, 2008Applicant: MURATA MANUFACTURING CO., LTD.Inventors: Hiroyuki Fujino, Yoshihiro Koshido, Naoko Aizawa, Hajime Yamada, Kenichi Uesaka

Patent number: 7259032Abstract: A method for manufacturing an electronic device includes the steps of forming a first resist pattern on a primary surface of a SAW element, the first resist pattern having openings at positions corresponding to those at which bumps and a sealing frame are to be formed, sequentially forming metals over the first resist pattern, the metals being formed into adhesion layers, barrier metal layers, and solder layers, removing the first resist pattern on the SAW element such that the bumps and the sealing frame are simultaneously formed. When the bumps and the sealing frame of the SAW element are bonded to bond electrodes of the bond substrate, the solder layers are melted and alloyed by heating.Type: GrantFiled: November 17, 2003Date of Patent: August 21, 2007Assignee: Murata Manufacturing Co., Ltd.Inventors: Koji Murata, Takashi Iwamoto, Hiroki Horiguchi, Ryuichi Kubo, Hidetoshi Fujii, Naoko Aizawa
