Latest Patents

Spencer's latest patents focus on thermally stabilized photoresist images. These photoresist image layers, especially those used for high-resolution geometries in microelectronic applications, are designed to be stabilized against distortion or degradation caused by heat during subsequent etching and ion implantation processes. The application of a film of a thermally stabilizing agent prior to the post-development bake of the image layer is a key aspect of his innovation. High-temperature resistant film-forming polymers, such as gelatin and gelatin hydrolysates, are preferred as thermally stabilizing agents. This process effectively achieves thermal stabilization of the photoresist image layer without significantly affecting the ease of subsequent stripping of the layer. It is particularly effective for thermally stabilizing positive resist images derived from photoresist systems based on novolak resins.
