Title: Chang-Zong Liu: Semiconductor Manufacturing and Process-Dispatching Innovations.

Introduction

Chang-Zong Liu is an inventor based in Hsinchu, Taiwan. His patent work includes systems and methods for assigning tools to production lots and dispatching lots through semiconductor manufacturing processes. He is associated with Taiwan Semiconductor Manufacturing Company Limited and has 6 patents.

Latest Patents

Liu’s listed recent patents address the coordination of production lots and manufacturing tools.

“Method and System for Lot-Tool Assignment” describes a dispatching system that provides preferences for tools associated with a lot. A processor uses those preferences to generate a tool-lot relationship and process the lot with one or more tools. The disclosure also covers a method and a non-transitory computer-readable medium.

“System and Method for Dispatching Lot” describes a process for selecting tools across multiple manufacturing stages. When a lot’s arrival times are earlier than its predetermined processing times, the system compares the idle times of available tools and processes the lot using the tool with the shortest idle time at each stage.

Career Highlights

Liu’s patent portfolio reflects work on manufacturing dispatch systems and tool selection. These inventions focus on using operational preferences and tool availability to guide lot processing across production stages.

Collaborations

Liu’s listed coworkers include An-Wei Peng and Ren-Chyi You. His work is associated with Taiwan Semiconductor Manufacturing Company Limited.

Conclusion

Chang-Zong Liu’s patents address practical challenges in semiconductor manufacturing by describing approaches to lot-tool assignment and production dispatching.
