ABSTRACT:
An electrostatic print head and method of fabrication therefor in which a head is provided having a precision high resolution array of styli of intended cross-section and an interconnect pattern for simple connection to driving circuits. A planar thin film pattern of spaced metal electrode lines is provided by photolithographic and electroforming techniques on one surface of a glass or ceramic substrate, and a spaced array of planar thin film buss lines are similarly formed on the opposite surface. The electrode lines and buss lines are formed by vacuum deposition of a metal onto the substrate surfaces, etching into intended patterns, and electroforming to the required thickness and cross-sections. Electronic components can be provided in film form on the same substrate as the electrode lines.
