Norbornane (also known as bicyclo[2.2.1]heptane) is an organic compound and a saturated hydrocarbon with chemical formula C₇H₁₂. It is a crystalline compound with melting point 88 °C. The carbon skeleton is derived from cyclohexane ring with a methylene bridge in the 1,4- position, and is a bridged bicyclic compound. The compound is a prototype of a class of strained bicyclic hydrocarbons.
Patterning process and resist composition
InactiveUS20080199806A1Avoid mixingPhotosensitive materialsRadiation applicationsNorbornaneNanotechnology
A pattern is formed by applying a positive resist composition comprising a polymer comprising 7-oxanorbornane ring-bearing recurring units and acid labile group-bearing recurring units and an acid generator onto a substrate to form a resist film, heat treating and exposing the resist film to radiation, heat treating and developing the resist film with a developer, and causing the resist film to crosslink and cure with the aid of acid and / or heat. A second resist pattern is then formed in the space area of the first resist pattern. The double patterning process reduces the pitch between patterns to one half.

Foamed polypropylene with improved cell structure
Alicyclic carboxylates, such as alicyclic norbonane sodium dicarboxylate, may be used in relatively small amounts as crystallization nucleating agents for foamed polypropylene. The alicyclic carboxylates give improved cell structures at lower proportions than conventional crystallization nucleating agents. The use of alicyclic carboxylate crystallization nucleating agents together with conventional nucleating agents may help give lower density polypropylene foams across a broader melt temperature range.
