Patent number: 8742589Abstract: A semiconductor embedded module 1 of the present invention has a configuration in which a semiconductor device 20, which is an electronic component such as a semiconductor IC (die) in a bare chip state, is embedded in a resin layer 10 (second insulating layer). In the semiconductor device 20, a redistribution layer 22 is connected to land electrodes. A protective layer 24 (first insulating layer) is provided on the redistribution layer 22, and is provided with openings such that external connection pads P of the redistribution layer 22 are exposed. Also, the resin layer 10 is formed to cover the protective layer 24, and vias V are formed at the positions of the respective external connection pads P of the redistribution layer 22. The grinding rate of the resin layer 10 is larger than that of the protective layer 24.Type: GrantFiled: July 17, 2009Date of Patent: June 3, 2014Assignee: TDK CorporationInventors: Kenichi Kawabata, Toshikazu Endo

Publication number: 20140040848Abstract: A typical post-out flow data path at the IC Fabrication has following major components of software based processing—Boolean operations before the application of resolution enhancement techniques (RET) and optical proximity correctin (OPC), the RET and OPC step [etch retargeting, sub-resolution assist feature insertion (SRAF) and OPC], post-OPCRET Boolean operations and sometimes in the same flow simulation based verification. There are two objectives that an IC Fabrication tapeout flow manager wants to achieve with the flow—predictable completion time and fastest turn-around time (TAT). At times they may be competing. An alternative method of providing target turnaround time and managing the priority of jobs while not doing any upfront resource modeling and resource planning is disclosed. The methodology systematically either meets the turnaround time need and potentially lets the user know if it will not as soon as possible.Type: ApplicationFiled: February 14, 2013Publication date: February 6, 2014Applicant: Mentor Graphics CorporationInventors: Toshikazu Endo, Minyoung Park, Pradiptya Ghosh, Steffen F.
