Abstract:
PROBLEM TO BE SOLVED: To provide a novel polymer easily spreadable on an electronic part with a very favorable electron insulating effect after cyclization, sufficient stability to chemicals and elevated temperatures, good adhesiveness and filling properties. SOLUTION: The present invention relates to an dielectric material for aluminum and copper metallizing being stable at elevated temperature. Polybenzoxazole is prepared by reacting bis-o-aminophenol with a dicarboxylic acid or its activated derivative (acid chloride) to give poly-o-hydroxamide followed by heating for dehydration and cyclization. The dielectric material of this polymer composition is very suitable for filling a narrow trench, surprisingly even though it is dehydrated during cyclization, and the filled trench shows no defect, bubble or crack. The polybenzoxazole has a low dielectric constant (≤2.7) and suitable for an electric insulator and further exhibits favorable adhesiveness to all the surfaces participating in microelectron optics.

The invention relates to a method for the production of semiconductor paths from an electrically-conducting organic material. Sections are defined on a substrate surface by printing of a matrix compound such that a substrate surface with hydrophilic and hydrophobic sections is obtained. A solution of the electrically-conducting organic polymer is applied to the structured substrate surface, whereby either only the hydrophilic sections or only the hydrophobic sections are coated with the solution of the organic polymer. The method permits the representation of lines with a linewidth of less then 10 µm and does not require any photolithographic process steps.
