    Abstract: OFFSET PRINTING FORM AND METHOD OF MAKING IT The offset printing form comprises a metal foil (1) rendered oleophobic and a superimposed micro-rough layer (2) in the form of the pattern to be printed, consisting of a resist filled with e.g. soot, possibly a thin metal layer (3) applied onto the resist layer (2), and a top layer (4) of photoresist. For making the offset printing form, a record carrier consisting of a metal foil (1) rendered oleophobic, a superimposed micro-rough resist layer (2) filled e.g. with soot, and a superimposed thin metal layer (3) with an inscribed pattern corresponding to the pattern to be printed, is blanket deposited with a layer (4) of a photoresist which is subsequently blanket irradiated, the radiation being reflected several times where the photoresist layer (4) lies on the metal layer (3), between the interface photoresist-aluminum and photoresist-air, and being subsequently developed. Simultaneously with development, or subsequently, exposed regions of metal layer (3) are removed, and finally the exposed regions of resist layer (2) are removed.

    Abstract: Disclosed is a process for passivating a first metallization pattern on a semiconductor substrate and providing a substantially planar quartz surface for subsequent metallization patterns in which a first polymer layer is applied over a first metallization layer and other portions of the substrate, providing a substantially planar surface. After a first curing, the first layer of polymer material is removed down to a thin layer of defined thickness over the first metallization pattern and, after a second curing, a quartz layer is applied over the polymer layer forming a substantially planar quartz top surface. Also disclosed is a method of forming via holes to the first metallization pattern as well as particular photoresist resins.
