Latest Patents

Among his latest patents is a method of making semiconductor devices and a control system for performing the same. This method involves calculating a processing tool offset for a processing tool, which is a first portion of a process offset time attributable to the processing tool. Additionally, it includes calculating a product offset, which is a second portion of the process offset time attributable to a product. The method also determines whether the product offset is stable based on a pre-determined tolerance and the number of processed wafers. Furthermore, it calculates an offset time for processing the product using the processing tool based on the calculated processing tool offset, without considering the product offset if the product offset is stable.

Another notable patent is related to IC manufacturing recipe similarity evaluation methods and systems. This method compares a first tool-log variable result from a first integrated circuit (IC) manufacturing recipe to a first tool-log variable result from a second IC manufacturing recipe. The comparison leads to generating instructions to add one of the recipes to an IC manufacturing recipe library or generating a defense report for one of the recipes.
