Patent number: 6680528Abstract: An electronic component having recesses on side faces of its package for housing an electric element therein. A metal layer that does not reach the bottom end of the package is formed on the surface of the recess.

Patent number: 6509636Abstract: A photosensitive semiconductor package with a lid is proposed, in which a chip carrier is formed with an encapsulant thereon, and the encapsulant is formed with a cavity for exposing a semiconductor chip mounted on the chip carrier. A top of the encapsulant is structured with a groove and at least a beveled portion that descends toward the groove and is associated with the groove. When a lid is attached onto the encapsulant by using an adhesive, the groove can temporarily retain excess adhesive with its flow being directed toward the groove by the beveled portion, so that undersirable adhesive loss and adhesive flash can both be prevented from occurrence, allowing the appearance of the semiconductor package to be well maintained.Type: GrantFiled: January 2, 2002Date of Patent: January 21, 2003Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Yueh-Ying Tsai, Chin-Yuan Hung, Chang-Fu Chen

Patent number: 6507104Abstract: A semiconductor package with an embedded heat-dissipating device is proposed. The heat-dissipating device including a heat sink and a plurality of connecting bumps attached to connecting pads formed on the heat sink is mounted on a substrate by reflowing the connecting bumps to ball pads of the substrate. The connecting bumps and the ball pads help buffer a clamping force generated during the molding process, so as to prevent a packaged semiconductor chip from being cracked. Moreover, the reflowing process allows the connecting bumps to be self-aligned on the substrate, so as to assure the toning and planarity of the heat sink mounted thereon. Accordingly, during molding, the precisely-positioned beat sink can have its upper side closely abutting an upper mold, allowing a molding resin to be prevented from flashing on the upper side thereof i.e.Type: GrantFiled: July 14, 2001Date of Patent: January 14, 2003Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Tzong Da Ho, Chien Ping Huang

Publication number: 20030001255Abstract: In a molding process, a hybrid integrated circuit substrate is fixed the position of the substrate in a thickness direction. A leadframe is connected, with an upward inclination, to a hybrid integrated circuit substrate and transported into a mold cavity. By horizontally fixing the leadframe by mold dies, the hybrid integrated circuit substrate inclined upward is urged downward by a pushpin. This can fix the position of the hybrid integrated circuit substrate within the mold cavity and integrally transfer-molded.Type: ApplicationFiled: June 27, 2002Publication date: January 2, 2003Inventors: Junichi Iimura, Katsumi Okawa, Yasuhiro Koike, Hidefumi Saito
