    摘要: Provided is a contact hole forming method, wherein in a thermal flow step the contact hole size can be fixed after thermal flow even if the resist material lot changes, or, wherein at the same bake temperature the contracted size, namely the flow amount, can be fixed. More specifically, provided is a contact hole forming method comprising a step of coating a resist material onto a substrate, a step of heating the coated resist material, a step of exposing the heated resist material to light through a photo mask adapted for a contact hole pattern, a step of heating the exposed resist material, a step of forming the contact hole pattern subsequently by developing with a developing fluid and a step of thermal flow treatment for heating the obtained contact hole pattern, wherein the resist material comprises an organic compound which does not react with the other components within the resist material and does not change a resolution property, and wherein when the resist material lot is changed, an amount of the organic compound to be added is changed so as to keep the contact hole pattern identical before and after the lot change.

    摘要: A negative pattern is formed by applying a resist composition onto a substrate, baking, exposing to high-energy radiation, baking (PEB), and developing the exposed resist film in an organic solvent developer to selectively dissolve the unexposed region of resist film. The resist composition comprising a hydrogenated ROMP polymer comprising recurring units having an acid labile group-protected carboxyl group and recurring units having a lactone structure displays a high dissolution contrast in organic solvent development, and exhibits high dry etch resistance even when the acid labile group is deprotected through exposure and PEB.

    摘要: A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid and (B) an acid generator. The resin (A) is a polymer comprising specific recurring units. When processed by ArF lithography, the composition is improved in resolution and forms a contact hole pattern with a satisfactory mask fidelity, sphericity and rectangularity.
