Patent number: 12080575Abstract: An airflow detection device is capable of detecting airflow issues associated with a transport carrier, such as a blockage of a diffuser in a transport carrier or leakage of a transition bracket, among other examples. The airflow detection device includes an air tunnel through which a gas in a transport carrier may flow. The airflow detection device includes an airflow sensor configured to generate airflow data based on a flow of the gas through the air tunnel. In some implementations, the airflow detection device is included in an airflow detection system to perform automated measurements and to determine, identify, and/or detect airflow issues associated with a transport carrier. In this way, the airflow detection system may perform one or more automated actions (or may cause one or more other devices to perform one or more automated actions) based on a detection of a diffuser blockage or a transition bracket leak.Type: GrantFiled: June 17, 2021Date of Patent: September 3, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yu-Chen Chen, Cheng-Lung Wu, Yang-Ann Chu, Jiun-Rong Pai, Ren-Hau Wu

Publication number: 20240234197Abstract: A wafer lift pin system is capable of dynamically modulating or adjusting the flow of gas into and out of lift pins of the wafer lift pin system to achieve and maintain a consistent pressure in supply lines that supply the gas to the lift pins. This enables the wafer lift pin system to precisely control the speed, acceleration, and deceleration of the lift pins to achieve consistent and repeatable lift pin rise times and fall times. A controller and various sensors and valves may control the gas pressures in the wafer lift pin system based on various factors, such as historic rise times, historic fall times, and/or the condition of the lift pins. This enables smoother and more controlled automatic operation of the lift pins, which reduces and/or minimizes wafer shifting and wafer instability, which may reduce processing defects and maintain or improve processing yields.Type: ApplicationFiled: March 25, 2024Publication date: July 11, 2024Inventors: Yu-Chen CHEN, Yi-Fam SHIU, Cheng-Lung WU, Yang-Ann CHU, Jiun-Rong PAI
