Abstract: PURPOSE: To obtain a composite material which allows the physical properties of a polymer material to be changed. CONSTITUTION: This material contains a composite materials of a fluorinated granular carbon dispersed in a polymer material and conductor pattern. The fluorocarbon content of the composite material is enough to make the dispersed content. of the composite material lower than that of the polymer material. The composite material can be made conductive by irradiating with an UV excimer laser.

Abstract: PURPOSE: To unnecessitate the use of dangerous or explosive chemicals in etching a polyimide layer by bringing the layer into successive contact with an aq. soln., an acid and a soln. CONSTITUTION: A satisfactorily or practically satisfactorily cured polyimide layer is brought into successive contact with an aq. metal. hydroxide soln., an acid and a metal hydroxide soln. The transfer of chemicals from one bath to other bath by which the service life of the baths is shortened by neutralization is suppressed and slight washing can be carried out.
