Latest Patents

Wilson holds a notable patent titled "Process for Increasing Resolution of Photolithographic Images." This invention describes conformable masking techniques that can be successfully utilized in practical manufacturing environments. The process enhances the resolution of photolithographic images while effectively eliminating defects that may arise from traditional masks used in the semiconductor industry.

The patent outlines a multi-step approach where a body is initially coated with a positive photoresist, which is then overcoated with a conformable mask. This mask is exposed through a fixed mask, and the subsequent development process defines a replica of the fixed mask, capturing its defects. The method prevents the reproduction of undesirable defects in the underlying photoresist, ensuring that only the intended regions receive exposure. Additionally, the introduction of a second conformable mask allows for refined image definition, ultimately enhancing the quality of the final product.
