Patent ID: 7906738

Claim:
A partially completed MEMS radio frequency electrical contact apparatus, comprising the combination of: a laterally disposed electrical insulating substrate member; a layer of thermally responsive and solvent responsive photoresist material received on an upper surface of said laterally disposed electrical insulating substrate member; a bulbous rounded corner indentation into an upper surface portion of said layer of thermally responsive and solvent responsive photoresist material, said bulbous rounded corner indentation being laterally aligned with a lower contact related element of said radio frequency MEMS electric contact apparatus that is also disposed on said laterally disposed electrical insulating substrate member; a layer of electroplate metal received on said upper surface portion of said layer of thermally responsive and solvent responsive photoresist material including said bulbous rounded corner indentation therein, said layer of electroplate metal comprising a movable contact carrying bias spring and integral bulbous movable contact element assembly portion of said radio frequency electric contact apparatus; and, a bath of photoresist dissolving solvent into which said electrical insulating substrate member, said photoresist layer and said movable contact carrying bias spring and integral bulbous movable contact element assembly portion of said radio frequency electrical contact apparatus is receivable for dissolution of said photoresist layer and release of said bulbous movable contact element assembly from photoresist captivity into a controllable state.
