With a remarkable portfolio of seven patents, Lin has established himself as a leading figure in his field, focusing on methods that enhance manufacturing efficiency and sustainability.

Latest Patents

Among his latest innovations are two patents related to copper plating methods. The first patent details a method for removing copper oxide from copper surfaces using vapor generated by an ultrasonic wave nebulizer. This process involves the application of energized vapor droplets, which include water mixed with weak organic acids such as acetic acid, lactic acid, and citric acid. These acids have a vapor pressure similar to that of water and are strategically chosen to avoid etching copper while effectively removing copper oxide, thereby supporting high throughput manufacturing.

The second patent focuses on activating a copper seed layer during the plating process, again utilizing vapor generated by an ultrasonic wave nebulizer. Similar to the previous method, this innovation applies weak acid/water vapor to a substrate in a spin bowl, followed by a deionized water rinse. The result is improved wettability that enhances the uniformity of the plated copper films. Both methods significantly reduce chemical consumption, leading to considerable cost savings and higher product yields.
