Claim:
1. A method of forming a micro-surface structure on or in a substrate having a substrate plane and producing a micro-electromechanical component, the method comprising: forming a first fine structure into the substrate, said first fine structure comprising a plurality of first projections comprising surfaces for coating with a getter material, said surfaces extending substantially perpendicular relative to the substrate plane; said surfaces of the first fine structure at least partially comprising wave-like projections and recesses acting as wave-like arrangement, wherein the wave-like arrangement as surface for depositing the getter material is provided by dry etching; depositing the getter material in a slanted direction relative to the substrate plane, whereby the wave-like projections and recesses as the first fine structure provide both, a shadowing effect and nucleation points as growing zones for a plurality of solid members, built by the slanted deposition of the getter material; the nucleation points primarily being the projections of the wave-like arrangement, and the getter material upon slanted impinging growing in the form of a second fine structure with plural solid members protruding from the first projections; and applying the micro-surface structure to the micro-electromechanical component.
