Title: Innovations by Yuh-Dean Tsay
Introduction
Yuh-Dean Tsay is a notable inventor based in Ping-Tung, Taiwan. He has made significant contributions to the field of semiconductor manufacturing, holding 2 patents that enhance the efficiency and safety of wafer transport systems.
Latest Patents
One of his latest patents is the "Interlock system for semiconductor wafer transport apparatus." This innovative system prevents collisions of handling equipment and protects wafers during manual control by an operator. It utilizes sensors to detect when both the wafer transport arms and the wafer stage are in their home positions. The controller responds to these sensors to operate the lockout system, ensuring that any attempt to activate the transport arm is locked out unless both components are correctly positioned. The lockout system is designed with normally closed electrical relays for added safety.
Another significant patent is the "Visualizing methods for dispatch and diagnosis of finite machines for semiconductor's manufacturing." This method provides a visual representation of the working conditions of semiconductor manufacturing machines. It collects data from various stages in a processing line, including "MAIN," "MRUN," "AFTER," and "PRE," which indicate the operational status of each stage. By arranging this data in bar charts, supervisors can easily assess the condition and priority of each stage-pair, facilitating better decision-making regarding tool allocation in the processing line.
