Abstract
Abstract An improved carrier for semiconductor chips is described. The carrier includes a base, a substrate including electrical conductors and a rectangular aperture for receiving the semiconductor chip mounted on the base. A transparent cover is installed over the chip and is retained there by a resilient metallic clip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A carrier for a microelectronic-circuit chip having beam leads to facilitate handling and testing operations, comprising: a base including a surface, a substrate mounted on the surface of said base, said substrate including a plurality of electrically conductive paths, said substrate further including a rectangular aperture through said substrate, each of said electrically conductive paths having an end adjacent said rectangular aperture, a microelectronic-circuit chip, said microelectronic-circuit chip further defined as being substantially rectangular in shape and having tapered sides, said microelectronic-circuit chip including a plurality of beam leads protruding from said circuit chip, said circuit chip aligned with said substrate entirely by cooperation of said tapered sides and said rectangular aperture, a cover retaining the circuit chip in said rectangular aperture, and resilient clip means for releasably holding said cover to said base, and, wherein said clip means includes a corregated leg and a J-shaped leg.
Claim 2
Dependent Claim
147 words
A carrier for a microelectronic-circuit chip having beam leads to facilitate handling and testing operations, comprising: a base including a surface, a substrate mounted on the surface of said base, said substrate including a plurality of electrically conductive paths, said substrate further including a rectangular aperture through said substrate, each of said electrically conductive paths having an end adjacent said rectangular aperture, a microelectronic-circuit chip, said microelectronic-circuit chip further defined as being substantially rectangular in shape and having tapered sides, said microelectronic-circuit chip including a plurality of beam leads protruding from said circuit chip, said circuit chip aligned with said substrate entirely by cooperation of said tapered sides and said rectangular aperture, a cover retaining the circuit chip in said rectangular aperture, and resilient clip means for releasably holding said cover to said base, and, wherein said clip means includes a corregated leg and a J-shaped leg.
Claim 3
Dependent Claim
