WebVoids were generally observed at the bottom of the HSQ line. Size and quantity of voids are larger for lower W/L ratios, indicating that the voids were formed due to insufficient HSQ volume for gap-filling. Increasing e-beam dose, baking or reflow temperature, and reflow of ZEP520A before HSQ coating could reduce the void formation. WebA method of forming a semiconductor device includes: forming a semiconductor feature over a substrate, the semiconductor feature includes a conductive region; forming a dielectric layer over the semiconductor feature; patterning the dielectric layer to form a contact opening exposing a top surface of the conductive region; forming a monolayer over the …

WebHSQ. HSQ, short for Hydrogen Silsesquioxane, is a negative-acting material that works well as an e-beam resist. It’s not a conventional resist, in that it’s not an organic polymer, it’s a spin-on-glass material that actually leaves behind an SiO2 material in exposed areas after development. It is sometimes known as the old trade name FOX ...
