Patent number: 9852256Abstract: A method for manufacturing a semiconductor device can reduce congestion across wires while reducing a wire length. The method includes determining a first TSV candidate region in a first die and determining a second TSV candidate region in a second die parallel to the first die. The method also includes determining a first bound region. The first bound region includes a horizontal location of a first pin of the first die and a horizontal location of a second pin of the second die. The method additionally includes calculating an area from overlapped regions between the first bound region and each of the first TSV candidate region and the second TSV candidate region, and performing routing for connecting the first pin and the second pin to each other based on the calculated area.Type: GrantFiled: August 4, 2014Date of Patent: December 26, 2017Assignee: Samsung Electronics Co., Ltd.Inventors: Myung-Soo Jang, Jae-Hwan Kim, Cheol-Jon Jang, Ji-Ho Song, Jong-Wha Chong, Kyung-In Cho

Patent number: 9135390Abstract: To design a power supply network of a 3D semiconductor device employing through-silicon-via (TSV) technology, board wiring of each of boards of the device is determined. An initial network structure is created for the boards. A layout of power bumps and through-silicon-vias, using the initial network structure, is produced such that voltages of all nodes of wiring of the boards are greater than a reference voltage. A semiconductor device having boards, power bumps and through-silicon-vias conforming to the layout is fabricated. Thus, the numbers of the through-silicon-vias and the power bumps of the power supply network of the semiconductor device are minimal.Type: GrantFiled: June 19, 2014Date of Patent: September 15, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Myung-Soo Jang, Jae-Rim Lee, Jong-Wha Chong, Jae-Hwan Kim, Byung-Gyu Ahn, Cheol-Jon Jang

Patent number: 7336704Abstract: Provided are a method of updating a tap coefficient of a channel equalizer while reducing the number of calculations and the divergence, and a circuit arranged and configured to execute the method. The method includes evaluating whether or not an error of the channel equalizer converges within a range of a threshold of visibility and determining the status of a control signal to select whether the tap coefficient of the channel equalizer will be updated using a least mean square (LMS) algorithm or a Kalman algorithm, wherein the LMS algorithm is the default error correction means and the Kalman algorithm is utilized when the control signal indicates the presence of a training signal.Type: GrantFiled: January 16, 2004Date of Patent: February 26, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Min-Ho Kim, Jung-Min Choi, Jong-Wha Chong
