Latest Patents

One of his latest patents is a slurry dispensing system. This system comprises a first supply station, a second supply station, a first loop, a second loop, a first valve, and a second valve. The first loop is selectively connected to both supply stations, allowing for efficient slurry distribution. The second loop also connects to the same supply stations, ensuring versatility in operation. When slurry is supplied to the first loop from the first slurry station, it is simultaneously supplied to the second loop from the second slurry station. The first valve connects the first loop to points of use, while the second valve connects the second loop to the same points. This innovative design allows for controlled slurry delivery based on operational needs.

Another significant patent by Chen is a wet dip method for photoresist and polymer stripping without a buffer treatment step. This method involves exposing a wafer to an etchant solution maintained at a temperature of at least 80°C. After exposure, the wafer is cooled in room temperature air until it reaches a substantially room temperature. The wafer is then rinsed using a quick dump rinse followed by a final rinse with deionized water, all without the need for a buffer solvent. This method enhances efficiency and simplifies the stripping process in semiconductor manufacturing.
