Filed: 1982-06-28
Abstract: PURPOSE:To perform the fine pattern copy in X-ray lithography with good accuracy by a method wherein the X-ray used for exposure is almost transmitted to the side wherein X-ray absorber patterns exist, and a thin conductive film supplied with potential is provided. CONSTITUTION:An X-ray mask 1 consists of a mask substrate 2, the Au X-ray absorber patterns 3, and mask substrate supporting bodies 4, and the thin conductive film 5 is formed on the mask substrate 2.

Abstract: PURPOSE:To high selectively produce a 1,4-dicyanobutene with industrial advantage by conducting dimerization of acrylonitrile in the presence of a phosphinite or phosphonite catalyst and in the coexistence a carbamic acid derivative. CONSTITUTION:This production of a 1,4-dicyanobutene is carried out by dimerizing acrylonitrile in the presense of a phosphinite catalyst or a phosphonite catalyst and in the coexistence of a carbamic acid derivative of the formula I (R is an alkyl, a cycloalkyl or an aryl; R' is H, an alkyl, a cycloalkyl or an aryl; a ring may be formed from R and R'). As the catalyst, a compound of the formula II or the formula III (R<1> to R<3>, R<1a> to R<3a>), e.g. methyldiphenyl phosphinite or diethylphenyl phosphonite is preferably used. In addition, a phosphinite catalyst is preferably used in view of stability of the catalyst. Since the dimerization is inhibited by water, the content of water is reduced recommendably to about 100ppm by a satisfactory drying treatment. This method is free from clogging and advantageous in view of operations.
