Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. COA of Formula: C7H12O3
Novel ester compounds having formula (1) wherein A1 is a polymerizable functional group having a double bond, A2 is furandiyl, tetrahydrofurandiyl or oxanorbornanediyl, R1 and R2 each are a monovalent hydrocarbon group, or R1 and R2 may bond together to form an aliphatic hydrocarbon ring with the carbon atom, and R3 is hydrogen or a monovalent hydrocarbon group which may contain a hetero atom are polymerizable into polymers. Resist compositions comprising the polymers are sensitive to high-energy radiation, have an improved sensitivity, resolution, and etching resistance, and lend themselves to micropatterning with electron beams or deep-UV rays. 1
