Latest Patents
Chiang's latest patents focus on the production of polyimides and their applications. One notable patent describes a process for producing polyimides by reacting two types of diamine compounds, including diaminopolysiloxane and a carboxyl group-containing diamine. Alternatively, it can involve three types of diamine compounds, which also include an aromatic or alicyclic diamine. This process utilizes a dicarboxylic acid anhydride with a 2,5-dioxotetrahydrofuryl group, leading to the formation of a polyamic acid that undergoes polyimidization. The resulting polyimide is soluble in low boiling organic solvents, such as methyl ethyl ketone. Additionally, a photosensitive composition that includes the polyimide, a photo crosslinking agent, and a photo acid-generating agent can create a negative type polyimide pattern when developed with an aqueous alkali solution.
