    摘要: A positive resist composition comprising a resin component having a solubility in an alkaline developer that increases under the action of an acid, a compound capable of generating an acid in response to actinic radiation, and an acidic organic compound having a molecular weight of at least 150 exhibits a high resolution and is effective in minimizing defects when processed by the photolithography. The composition is thus quite effective for precise micropatterning.

    摘要: A polymer comprising recurring units of formulae (1), (2), (3) and (4) increases a dissolution rate in an alkali developer under the action of an acid. R1, R2, R3 and R6 are H or CH3, R4 and R5 are H or OH, X is a tertiary exo-alkyl group having a bicyclo[2.2.1]heptane framework, represented by any of formulae (X-1) to (X-4): wherein R7 is C1-C10 alkyl, and Y is a tertiary alkyl group having an adamantane structure. A resist composition comprising the inventive polymer has a sensitivity to high-energy radiation, improved resolution and minimized proximity bias and lends itself to micropatterning with electron beams or deep UV for VLSI fabrication.

    摘要: A drill includes a pair of main cutting edges extending from a distal portion of the drill to a position close to a proximal end of the drill to entirely define a two-edge configuration, and a pair of auxiliary cutting edges extending between positions at the distal and proximal sides of a maximum diameter position to partly define a four-edge configuration. A ridgeline of each auxiliary cutting edge is located within an angle smaller than 90° from a ridgeline of the corresponding main cutting edge toward the rear in a rotation direction of the drill. The point angle of the auxiliary cutting edges increases at a higher rate than the point angle of the main cutting edges in a predetermined range from the maximum diameter position toward a distal end of the drill.

    摘要: A partially tert-butoxylated poly(p-hydroxystyrene) is prepared by subjecting poly(p-tert-butoxystyrene) to reaction of eliminating some of the tert-butoxy groups in an organic solvent at a temperature of 30.degree.-100.degree. C. in the presence of an acid catalyst at a molar ratio of acid catalyst/t-BuO group of from 0.050 to 2.0. During the elimination reaction, a change of solubility of the resulting partially tert-butoxylated poly(p-hydroxystyrene) is determined to calculate a degree of elimination of tert-butoxy groups. The reaction is terminated when a desired degree of elimination is reached. Through a simple process, partially tert-butoxylated poly(p-hydroxystyrene) having a well controlled t-BuO content is produced in high yields.
