Abstract: A method for manufacturing X-ray lithography masks containing features smaller than 1 micron in size and having conductive or non-conductive substrates. The method involves the initial deposition, as by evaporation, of a very thin coating of a strong X-ray absorber such as gold. A layer of photoresist is applied to the initial gold layer and exposed and developed to remove the photoresist in the exposed areas. Thereafter, the mask is submerged in an electroless gold plating bath. I have discovered that metals suitable for electroless plating are autocatalytic in nature. Accordingly, additional gold from the bath is preferentially deposited on the exposed first gold layer and is permitted to build to the desired thickness.

Abstract: Method and apparatus for removing a resist layer from a substrate surface of different material, such as a semiconductor slice, in the fabrication of an electronic structure, involving exposure of the resist layer to a flame from a combustible gas. The resist layer is employed as a mask in patterning the substrate surface via selective etching, diffusion, or other procedures and is removed from the substrate when it has served its purpose. The resist material may include not only light-sensitive resists more commonly termed "photoresists", but also electron beam-sensitive resists, and resists applied by stencil techniques. The resist layer is exposed to the flame for a period of time sufficient to decompose the resist material, the length of the exposure being a function of several factors, including the type of resist, the thickness of the layer, and the manufacturing processes to which the slice was subjected prior to the resist removal step.

Abstract: A contrasting color is imparted to the decorative surface of a decorative laminate by inserting a pigment coated release sheet between the molding caul and the decorative surface during the molding operation, with the pigment facing the decorative surface. Upon application of heat and pressure during the formation of the laminate, color is transferred from the release sheet to the decorative surface. A suitable technique is also used to emboss or impart surface texture to the decorative surface during molding. Thereafter, the textured surface is subjected to rubbing or brushing to remove more color from the embossed or raised areas than the debossed areas, thereby highlighting or imparting a shaded effect to the textured surface.
