Patent number: 12211699Abstract: A method of removing a step height on a gate structure includes providing a substrate. A gate structure is disposed on the substrate. A dielectric layer covers the gate structure and the substrate. Then, a composite material layer is formed to cover the dielectric layer. Later, part of the composite material layer is removed to form a step height disposed directly on the gate structure. Subsequently, a wet etching is performed to remove the step height.

Patent number: 12147163Abstract: A method for correcting critical dimension (CD) measurements of a lithographic tool includes steps as follows. A correction pattern having a first sub-pattern parallel to a first direction and a second sub-pattern parallel to a second direction is provided on a lithographic mask; wherein the first sub-pattern and the second sub-pattern come cross with each other. A first After-Develop-Inspection critical dimension (ADI CD) of a developed pattern formed on a photo-sensitive layer and transferred from the correction pattern is measured using the lithographic tool along a first scanning direction. A second ADI CD of the developed pattern is measured using the lithographic tool along a second scanning direction. The first ADI CD is subtracted from the second ADI CD to obtain a measurement bias value. Exposure conditions and/or measuring parameters of the lithographic tool are adjusted according to the measurement bias value.Type: GrantFiled: November 17, 2021Date of Patent: November 19, 2024Assignee: UNITED MICROELECTRONICS CORP.Inventors: Hsin-Yu Hsieh, Kuan-Ying LAi, Chang-Mao Wang, Chien-Hao Chen, Chun-Chi Yu

Patent number: 11722969Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine separate uplink (UL) power limitations for multiple transmission time interval (TTI) durations based on distinct power control parameters. In some cases, an adjustment factor or a power backoff may be applied to communications using one TTI duration to ensure that total transmit power does not exceed a threshold. The UE and the serving base station may also identify one or more demodulation reference signal (DMRS) windows. UL data transmissions may be demodulated based on a DMRS sent during the same window. Transmit power control (TPC) commands may be applied at the beginning of each window. However, if an UL transmission is scheduled at the beginning of the window, the UE may wait until a DMRS transmission or until no more transmissions are scheduled for the window before applying the TPC adjustment.Type: GrantFiled: January 8, 2021Date of Patent: August 8, 2023Assignee: QUALCOMM IncorporatedInventors: Shimman Arvind Patel, Wanshi Chen, Peter Gaal, Hao Xu, Michael Mao Wang

Patent number: 11581999Abstract: Methods, systems, and devices are described for reference signal design in wireless communications. A base station may select a reference signal density scheme from a set of available density schemes associated with a port count. The reference signal density scheme may also be selected based on the category of the mobile device receiving the reference signal transmissions. The reference signal density scheme may be a higher density reference signal density scheme or a lower density reference signal density scheme, where the higher density reference signal density scheme includes more reference signal resource elements per subframe. The mobile device may determine the reference signal density scheme based on characteristics of a channel. The higher density reference signal density scheme may provide additional channel estimation opportunities for the mobile device. In some cases, the mobile device sends the channel estimated based on the received reference signals to the base station.Type: GrantFiled: October 6, 2015Date of Patent: February 14, 2023Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Michael Mao Wang, Hao Xu, Yongbin Wei, Peter Gaal
