Latest Patents

One of his latest patents is the "Lift-off masking method." This invention describes a lift-off process for depositing a metallurgy layer on a substrate. The improvement lies in the use of a sacrificial masking layer that remains largely unaffected by high-intensity radiation exposure. The process involves several steps, including preparing a resin mixture, depositing a blanket sacrificial masking layer, selectively removing areas to define the metallurgy pattern, depositing a conductive metal layer, and finally exposing the coated wafer to a solvent to remove the masking layer.

Another significant patent by Ouano is focused on the "Enhancement of resist development." This invention aims to achieve a high solubility rate ratio between exposed and unexposed regions of a resist, as well as shorter development times. The objectives are accomplished by treating the resist with a liquid trialkylamine that contains two to eight carbon atoms in each alkyl group.
