Latest Patents

One of his latest patents is titled "Device and method of decreasing circular defects and charge buildup." This invention provides an apparatus and method for decreasing circular defects and charge buildup on a semiconductor wafer that has a photoresist formed on it. The method involves positioning a semiconductor wafer in a track developer and applying a photoresist developer at a predetermined speed. The initial speed is then increased to a range of about 400 rpm to 800 rpm. During the rinsing process, the photoresist is removed from the semiconductor while a back spray is applied to the second side of the semiconductor. Additionally, the semiconductor wafer is subjected to a flow of ions from an ionization source within the tracking device itself. This ionization is a significant advantage over prior art systems, as it reduces the charge buildup associated with increased spin speeds.

Another important patent by Huibregtse is related to "Integrated circuit fabrication." This invention focuses on coating the quartz shadow ring of a conventional plasma etching apparatus with material that inhibits the liberation of oxygen into the plasma. Research has shown that liberated oxygen can degrade etching uniformity across the wafer, making this innovation crucial for improving manufacturing processes.
