Publication number: 20080099902Abstract: The present invention provides an insertion-type semiconductor device and a fabrication method thereof, including the steps of: mounting a chip on a BGA substrate and performing a packaging molding process; providing an electrical connecting board formed with a plurality of electrical terminals thereon for allowing the packaged substrate to electrically connect with the electrical terminals on the electrical connecting board via a conductive element thereof; covering a lid to form an insertion-type semiconductor device. As size of the solder pads is much smaller than the electrical terminals of the insertion-type semiconductor device, the area under the semiconductor chip can be reduced to minimize the deformable area of the semiconductor chip when being pressed in the molding process, thereby preventing damage to the semiconductor chip and also meeting the specification requirement of an insertion-type semiconductor device.Type: ApplicationFiled: February 14, 2007Publication date: May 1, 2008Applicant: Siliconware Precision Industries Co., Ltd.Inventors: Ming-Ke Shih, Ping-Yi Chu, Yong-Liang Chen, Chien-Chih Sung, Chung-Pao Wang

The passive component is located under the stepwise chips that are cantilevered over it. Therefore, the passive component serves as a block element or a filling element in the molding process, and problems such as chip peeling void are prevented. Meanwhile, the electrical properties of the package are improved.Type: ApplicationFiled: November 1, 2006Publication date: July 26, 2007Applicant: Siliconware precision industries Co., Ltd.Inventors: Kun-Chen Liu, Chien-Chih Chen, Chung-Pao Wang

Publication number: 20070166884Abstract: A circuit board and a package structure thereof are proposed. The circuit board includes a main body and a solder mask layer covered on a surface of the main body. The circuit board is formed with a cutting path to define a plurality of array-arranged circuit board units, wherein the solder mask layer is formed with a groove at a position corresponding to the cutting path to expose the main body of the circuit board. By such arrangement, when a laser is employed to perform a singulation process after a chip mounting process and a packaging process have been completed on the circuit board unit, the problem wherein the solder mask layer melts on the cutting path of the circuit board due to a thermal effect caused by the laser is avoided, so as to avoid the generation of irregular and uneven surface of the cutting plane. Additionally, chippings on a surface of a substrate can be prevented from being generated, so as to avoid contamination of subsequent processes.Type: ApplicationFiled: August 1, 2006Publication date: July 19, 2007Applicant: Siliconware Precision Industries Co., Ltd.Inventors: Hao Wei Li, Chien Chih Chen, Chung Pao Wang, Yung Chuan Ku, Yun Lung Tsai

Patent number: 6441501Abstract: A wire-bonded semiconductor device with an improved wire-arrangement scheme is proposed, which can help minimize abnormal wire sweep during encapsulation process. Among the bonding wires on the semiconductor device, those located in corners would be mostly susceptible to abnormal wire sweep, particularly a high-loop bonding wire that is located in immediate adjacency to a low-loop bonding wire located in one corner of the wire-bonded semiconductor device. To solve this problem, the low-loop bonding wire that is located in immediate adjacency to the sweep-susceptible high-loop bonding wire is erected substantially to the same loop height as the high-loop bonding wire, so that it can serve as a shield to the sweep-susceptible high-loop bonding wire against the flow of injected resin during encapsulation process, thus preventing abnormal wire sweep.Type: GrantFiled: September 30, 2000Date of Patent: August 27, 2002Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Charles Tseng, Chin-Te Chen, Yu-Ting Lai, Chung-Pao Wang
