Patent ID: 7160743

Claim:
A method of fabricating a light emitting semiconductor packages from a semiconductor wafer comprising a plurality of light emitting devices manufactured on or in the wafer surface, the method comprising the steps of: (B) forming at least one first hollow cap, each first hollow cap formed to provide: (1) a central portion and first perimeter walls extending from the perimeter edge of the central portion with the free edges of the first perimeter walls adapted to be bonded to the surface of the semiconductor wafer to provide a first cavity; (2) at least one region of the central portion which is substantially transparent or translucent to electromagnetic radiation emitted by the light emitting devices; (C) aligning the at least one first cap with a corresponding at least one light emitting device using a tool having the same coefficient of thermal expansion as the wafer; (D) bonding the at least one first hollow cap to the semiconductor wafer, the central portion overlying at least one of the corresponding light emitting devices; and (E) separating the semiconductor wafer with bonded caps into light emitting semiconductor packages.
