Patent number: 11926787Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.Type: GrantFiled: April 21, 2020Date of Patent: March 12, 2024Assignees: PetroChina Company Limited, CNPC Engineering Technology R&D Company LimitedInventors: Shuoqiong Liu, Hua Zhang, Jianzhou Jin, Ming Xu, Yongjin Yu, Fengzhong Qi, Congfeng Qu, Hong Yue, Youcheng Zheng, Wei Li, Yong Ma, Youzhi Zheng, Zhao Huang, Jinping Yuan, Zhiwei Ding, Chongfeng Zhou, Chi Zhang, Zishuai Liu, Hongfei Ji, Yuchao Guo, Xiujian Xia, Yong Li, Jiyun Shen, Huiting Liu, Yusi Feng, Bin Lyu

Patent number: 9269651Abstract: A semiconductor chip includes a substrate and a semiconductor layer positioned above the substrate. A hybrid through-silicon via (“TSV”) extends continuously through at least the semiconductor layer and the substrate and includes a first TSV portion and a second TSV portion. A lower portion of the first TSV portion is positioned in the substrate and has a lower surface adjacent to a back side of the substrate and an upper surface below the semiconductor layer. Upper sidewall portions of the first TSV portion extend from the upper surface through at least the semiconductor layer. A depth of the lower portion is greater than a thickness of the upper sidewall portions. The second TSV portion is conductively coupled to the first TSV portion, is laterally surrounded by the upper sidewall portions, and extends continuously from the upper surface through at least the semiconductor layer.Type: GrantFiled: February 25, 2015Date of Patent: February 23, 2016Assignee: GLOBALFOUNDRIES Singapore PTE LTDInventors: Yu Hong, Liu Huang, Zhao Feng

Patent number: 6850753Abstract: A radio frequency front-end receiver includes a single stage low noise amplifier connected with a resistor array and a capacitor array, and a Gilbert-type mixer connected with a PMOS transconductance stage, an inductor and a serially connected current source. The resistor array enables the adjustment of the power gain of the low noise amplifier. The capacitor array tunes the low noise amplifier so that the maximum power gain is at the desired operating frequency. The PMOS transconductance stage reduces the power consumption of the mixer. The inductor increases the impedance and the current source improves the common-mode rejection of the mixer.Type: GrantFiled: June 11, 2002Date of Patent: February 1, 2005Assignee: MuChip Co., LtdInventors: Zhao-Feng Zhang, David Jan-Chia Chen, Zhen-Chuan Liu, Meng-Hsiang Lai
