Patent number: 8647924Abstract: A method of forming a device stack is presented. The method includes providing a temporary substrate having a temporary mounting surface. A first chip is temporarily mounted to the temporary mounting surface. A first bottom surface of the first chip is temporarily mounted to the temporary mounting surface and a first top surface of the first chip comprises first interconnects. A second chip is stacked on the first chip. The second chip includes second conductive contacts on the second bottom surface. The method also includes bonding the first and second chips together to form the device stack. The second conductive contacts are coupled to the first interconnects. The first bottom surface of the first chip is separated from the substrate to separate the chip stack from the substrate.Type: GrantFiled: April 13, 2010Date of Patent: February 11, 2014Assignee: United Test and Assembly Center Ltd.Inventors: Chin Hock Toh, Keng Yuen Au, Reynaldo Vincent Hernandez Sta Agueda, Bee Liang Catherine Ng, Librado Amurao Gatbonton, Xue Ren Zhang, Yi-Sheng Anthony Sun

Publication number: 20130242497Abstract: A multi-serial port connection device has a connection card and a cable. The connection card has a serial signal transceiving control module and at least one Mini DisplayPort connector. The serial signal transceiving control module has at least two sets of serial I/O pins compatible with DB9 connector standard. The two sets of serial I/O pins are connected to twenty contacts of the Mini Display Port connector. The cable has a plug, at least two DB9 sockets for the connection of two external electronic devices with DB9 connectors. The multi-serial port connection device can reduce the space occupied by connectors on the connection card.Type: ApplicationFiled: December 17, 2012Publication date: September 19, 2013Applicant: SUNIX CO., LTD.Inventors: Ming-Cheng LIN, Pei-Feng HUANG, Zhong-Ren ZHANG

Patent number: 8384203Abstract: A structural member for use in semiconductor packaging is disclosed. The structural member includes a plurality of packaging regions to facilitate packaging dies in, for example, a wafer format. A packaging region has a die attach region surrounded by a peripheral region. A die is attached to the die attach region. In one aspect, the die attach region has opening through the surfaces of the structural member for accommodating a die. Through-vias disposed are in the peripheral regions. The structural member reduces warpage that can occur during curing of the mold compound used in encapsulating the dies. In another aspect, the die attach region does not have an opening. In such cases, the structural member serves as an interposer between the die and a substrate.Type: GrantFiled: July 20, 2009Date of Patent: February 26, 2013Assignee: United Test and Assembly Center Ltd.Inventors: Chin Hock Toh, Yi Sheng Anthony Sun, Xue Ren Zhang, Ravi Kanth Kolan
