Patent number: 10673104Abstract: A method is provided for testing a semi-finished battery cell. The semi-finished battery cell is charged with a constant current when a voltage difference between the first conductor and the second conductor is less than a voltage threshold. The semi-finished battery cell is charged with a constant voltage when the voltage difference between the first conductor and the second conductor is equal to or larger than the voltage threshold. An overall electric quantity is obtained after a default time period, wherein the overall electric quantity is an electric quantity charged to the semi-finished battery cell with the constant current during the default time period. Accordingly, an insulation related to electrodes of the semi-finished battery cell is determined as poor when the overall electric quantity is larger than an electric quantity threshold.Type: GrantFiled: March 5, 2018Date of Patent: June 2, 2020Assignee: CHROMA ATE INC.Inventors: Chih-Ming Tsai, Chao-Hsu Chen, Han-Chou Liao, Chung-Yu Siang

Patent number: 10158004Abstract: Some embodiments of the present disclosure relates to a method of forming a semiconductor device having a strained channel and an associated device. In some embodiments, the method includes performing a first etching process by selectively exposing a substrate to a first etchant to produce a recess defined by sidewalls and a bottom surface of the substrate. An implantation process is performed to form an etch stop layer along the bottom surface. A second etching process is performed by exposing the sidewalls and the bottom surface defining the recess to a second etchant to form a source/drain recess. The source/drain recess laterally extends past the etch stop layer in opposing directions. A semiconductor material is formed within the source/drain recess.Type: GrantFiled: July 17, 2017Date of Patent: December 18, 2018Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chao-Hsuing Chen, Ling-Sung Wang, Chi-Yen Lin

Patent number: 9831314Abstract: One or more techniques or systems for controlling a profile of a surface of a semiconductor region are provided herein. In some embodiments, an etching to deposition (E/D) ratio is set to be less than one to form the region within the semiconductor. For example, when the E/D ratio is less than one, an etching rate is less than a deposition rate of the E/D ratio, thus ‘growing’ the region. In some embodiments, the E/D ratio is subsequently set to be greater than one. For example, when the E/D ratio is greater than one, the etching rate is greater than the deposition rate of the E/D ratio, thus ‘etching’ the region. In this manner, a smooth surface profile is provided for the region, at least because setting the E/D ratio to be greater than one enables etch back of at least a portion of the grown region.Type: GrantFiled: August 3, 2015Date of Patent: November 28, 2017Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Chao-Hsuing Chen, Ling-Sung Wang, Chi-Yen Lin

Patent number: 9735252Abstract: Some embodiments of the present disclosure relates to a method of forming a transistor device having a strained channel and an associated device. In some embodiments, the method is performed by performing a first etch of a substrate to produce a recess having a largest width at an opening along a top surface of the substrate.
