    摘要: According to the method for preparing hexamethyl cyclotrisilazane of the present invention, hexamethyl cyclotrisilazane can be obtained by heating a linear or cyclic silazane compound represented by the following general formula:--(Me.sub.2 SiNH).sub.n --(wherein Me represents a methyl group and n is an integer of not less than 4) in the presence of at least one catalytic compound selected from the group consisting of ammonium salts of arylsulfonic acids and/or aminoarylsulfonic acids and the resulting hexamethyl cyclotrisilazane represented by the formula: --Me.sub.2 SiNH).sub.3 -- can be recovered by distilling off the same outside the reaction system. According to the method of the present invention, highly pure hexamethyl cyclotrisilazane can be industrially prepared in good efficiency and in a high yield. In particular, if octamethyl cyclotetrasilazane which can be industrially prepared from cheap dimethyldichlorosilane is used as a starting material, hexamethyl cyclotrisilazane can also be prepared at a low cost. Thus, the method of the present invention has enough practical value in the organic silicon industries.

    摘要: Double patterns are formed by coating a chemically amplified positive resist composition comprising an acid labile group-bearing resin and a photoacid generator and prebaking to form a resist film on a processable substrate, exposing the resist film to high-energy radiation, PEB, and developing with an alkaline developer to form a positive resist pattern, treating the positive resist pattern to be alkali soluble and solvent resistant, coating a negative resist composition and prebaking to form a reversal film, and exposing the reversal film to high-energy radiation, PEB, and developing with an alkaline developer to form a negative resist pattern. The last development step includes the reversal transfer step of dissolving away the positive resist pattern which has been converted to be soluble in developer.
