Abstract:
A contact structure for establishing electrical communication with contact targets, comprising:a plurality of contact beams each of which exhibits a spring force in a transversal direction thereof to establish a contact force when a tip of said contact beam pressed against a contact target, each of said contact beam comprising: a silicon base having at least one inclined portion which is created through an anisotropic etching process, said contact beam being projected from said silicon base; an insulation layer formed on said contact beam for electrically insulating said contact beam from said silicon base; and a conductive layer made of conductive material formed on the insulation layer in such a way that said contact beam is configured by the insulation layer and the conductive layer equally projected from said silicon base; a contact substrate for mounting said plurality of contact beams, said contact substrate having a planar surface for mounting thereon said silicon base in a manner to fix said contact beam in a diagonal direction by means of an adhesive; and a plurality of contact traces provided on the surface of said contact substrate and respectively connected to said contact beams to establish signal paths toward electrical components.
