Abstract
A contact structure for establishing electrical communication with contact targets with improved contact performance including frequency bandwidth, contact pitch, reliability and cost. The contact structure is formed of a plurality of finger like contactors mounted on a contact substrate. Each of the contactors includes a silicon base having an inclined support portion, an insulation layer formed on the silicon base and projected from the inclined support, and a conductive layer made of conductive material formed on the insulation layer so that a beam portion is created by the insulation layer and the conductive layer, wherein the beam portion exhibits a spring force in a transversal direction of the beam portion to establish a contact force when the tip of the beam portion pressed against a contact target. An adhesive is applied for bonding the contactors to the surface of the contact substrate.
