Latest Patents

Among Takashi Chiba's notable patents are two that showcase his expertise and innovation in the realm of immersion upper layer film compositions and fine pattern formations.

1. **Immersion Upper Layer Film Forming Composition and Method of Forming Photoresist Pattern**

This patent describes an immersion upper layer film composition that includes a resin and a solvent. The resin creates a water-stable film when irradiated and dissolves in a subsequent developer. The solvent features a monovalent alcohol with six or fewer carbon atoms. This composition is specifically designed for use in an immersion exposure process, which aids in the efficient irradiation of the photoresist film through water positioned between the lens and the film.

2. **Resin Composition for Forming Fine Pattern and Method for Forming Fine Pattern**

In this patent, Chiba developed a resin composition that enhances the process of forming a fine pattern through heat treatment of a resist pattern made with a photoresist. The resin composition allows the resist pattern to shrink smoothly during heat treatment and facilitates easy washing away with an alkaline aqueous solution. It contains a resin with a hydroxyl group, a crosslinking component, and an alcohol solvent with a limited water content.
