Patent number: 9721936Abstract: Field-effect transistor (FET) stack voltage compensation. In some embodiments, a switching device can include a first terminal and a second terminal, and a plurality of switching elements connected in series between the first and terminal and the second terminal. Each switching element has a parameter that is configured to yield a desired voltage drop profile among the connected switching elements. Such a desired voltage drop profile can be achieved by some or all FETs in a stack having variable dimensions such as variable gate width or variable numbers of fingers associated with the gates.Type: GrantFiled: August 4, 2014Date of Patent: August 1, 2017Assignee: Skyworks Solutions, Inc.Inventors: Yu Zhu, David Scott Whitefield, Ambarish Roy, Guillaume Alexandre Blin

Patent number: 9721939Abstract: Aspects of the invention provide a compact semiconductor device having a surge protection element, which can reliably protect against surge and is unlikely to be affected by manufacturing variation. By forming a parasitic n-p-n transistor on a guard ring, and adopting the parasitic n-p-n transistor as a surge protection element, it is possible to provide a compact semiconductor device having a surge protection element. Also, by adopting the parasitic n-p-n transistor as a surge protection element, it is possible to reduce the operating resistance in comparison with when using a parasitic n-p-n transistor as a surge protection element, and thus possible to improve the surge protection function. Further, by providing one surge protection element on the guard ring, rather than providing a surge protection element in each cell, it is possible minimize the effect of manufacturing variation (i.e., in-plane variation) on the surge protection function.Type: GrantFiled: July 12, 2013Date of Patent: August 1, 2017Assignee: FUJI ELECTRIC CO., LTD.Inventor: Taichi Karino

Patent number: 9721941Abstract: The present examples relate to a semiconductor chip having a level shifter with an electrostatic discharge (ESD) protection circuit and a device applying to multiple power supply lines with high and low power inputs to protect the level shifter from the static ESD stress. More particularly, the present examples relate to using a feature to protect a semiconductor device in a level shifter from the ESD stress by using ESD stress blocking region adjacent to a gate electrode of the semiconductor device. The ESD stress blocking region increases a gate resistance of the semiconductor device, which results in reducing the ESD stress applied to the semiconductor device itself.Type: GrantFiled: July 20, 2015Date of Patent: August 1, 2017Assignee: Magnachip Semiconductor, Ltd.Inventors: Kyong Jin Hwang, Hyun Kwang Jeong

Patent number: 9721942Abstract: By holding a voltage that depends on a video signal in a first capacitor, holding a voltage that depends on a threshold voltage of a transistor in a second capacitor, and then applying a total voltage of the voltage held in the first capacitor and the voltage held in the second capacitor between a source and a gate of the transistor, even when the threshold voltage varies, a current corresponding to the video signal can be supplied to a load. The voltage that depends on the video signal and the voltage that depends on the threshold voltage of the transistor are separately acquired.Type: GrantFiled: April 17, 2015Date of Patent: August 1, 2017Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Hajime Kimura

Patent number: 9721943Abstract: A wiring structure may include at least two conductive material layers and a two-dimensional layered material layer in an interface between the at least two conductive material layers. The two-dimensional layered material layer may include a grain expander layer which causes grain size of a conductive material layer which is on the two-dimensional layered material layer to be increased. Increased grain size may result in resistance of the second conductive material layer to be reduced. As a result, the total resistance of the wiring structure may be reduced. The two-dimensional layered material layer may contribute to reducing a total thickness of the wiring structure. Thus, a low-resistance and high-performance wiring structure without an increase in a thickness thereof may be implemented.Type: GrantFiled: February 24, 2016Date of Patent: August 1, 2017Assignee: Samsung Electronics Co., Ltd.Inventors: Changseok Lee, Keunwook Shin, Hyeonjin Shin, Seongjun Park, Hyunjae Song, Hyangsook Lee, Yeonchoo Cho
