Abstract:
1. An apparatus for aligning a first substrate relative to a second substrate wherein the first substrate includes a front surface, a rear surface and at least one micro-component disposed on the front surface and the second substrate includes a front surface, a rear surface and at least one micro-component disposed on the front surface and wherein the front surfaces of the first and second substrates are oriented in the same direction, the apparatus comprising: a pyramidally-shaped alignment member having a pair of side surfaces and an apex mechanically receivable within a recess disposed in said front surface of the first substrate; said apex configured to partially project through the rear surface of said first substrate to mechanically engage a recess disposed on the front surface of the second substrate; and said side surfaces and said apex cooperating to passively align the micro-components disposed on each of said substrates.
