Strategic Insights

Oct 26, 2025 — 1 min read

A new patent has been granted to Semes Co. Ltd. for a carriage robot and tower lift design specifically tailored for semiconductor manufacturing. This innovative design addresses the challenges of transporting multiple containers of varying sizes in a vertical direction, without compromising transport efficiency. The patented invention provides a solution to the current limitations of container transport systems in semiconductor manufacturing.

Key Takeaways:

The patented invention includes a carriage robot that features a robot arm with stacked arms, where the uppermost arm has a thickness matching the height of the second container, allowing for simultaneous transportation of multiple containers.
The carriage robot includes a gripper that can grip a second container having a different size in a sliding way, ensuring that the container is securely transported without falling or vibrating.
The tower lift design features a guide rail that extends in a vertical direction, with the carriage robot being movable in the vertical direction along the guide rail, allowing for efficient transportation of containers.
The patented design includes a controller that can adjust the operating speed of the robot arm differently for first and second containers, ensuring optimal transport efficiency.
The invention also includes a guide part and a supporting pin to suppress container vibration and ensure safe transportation.
The carriage robot and tower lift invention provides a significant improvement in container transport efficiency and safety in semiconductor manufacturing.
