Abstract
Abstract A semiconductor device carrier includes a carrier substrate having an open section in which a semiconductor device is accommodated, and a retaining member slidably coupled to the carrier substrate which linearly recriprocates on a surface of the carrier substrate having the open section and which is provided with a retaining element adapted to retain the semiconductor device accommodated within the open section of the carrier substrate when the retaining member has moved in one direction and to release the retention of the semiconductor device when the retaining member has moved in the other direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
An apparatus for carrying a semiconductor device, said apparatus comprising: a carrier substrate having a generally planar upper surface, said carrier substrate having an open section extending therein that is open at said upper surface, the semiconductor device being disposed in the open section when carried by the apparatus; and a retaining member slidably mounted on said carrier substrate for moving relative to said carrier substrate along a linear path between first and second positions, said path extending substantially parallel to said upper surface, said retaining member having a retaining section facing said upper surface and which is slidable relative to and over said upper surface toward and away from said open section when the retaining member is moved along said path between said first and said second positions, the retaining section being positioned over the semiconductor device for retaining the semiconductor device in the open section after said retaining member is moved to said first position along said linear path and for releasing the semiconductor device when said retaining member is moved to said second position along said linear path.
Claim 2
Independent Claim
181 words
An apparatus for carrying a semiconductor device, said apparatus comprising: a carrier substrate having a generally planar upper surface, said carrier substrate having an open section extending therein that is open at said upper surface, the semiconductor device being disposed in the open section when carried by the apparatus; and a retaining member slidably mounted on said carrier substrate for moving relative to said carrier substrate along a linear path between first and second positions, said path extending substantially parallel to said upper surface, said retaining member having a retaining section facing said upper surface and which is slidable relative to and over said upper surface toward and away from said open section when the retaining member is moved along said path between said first and said second positions, the retaining section being positioned over the semiconductor device for retaining the semiconductor device in the open section after said retaining member is moved to said first position along said linear path and for releasing the semiconductor device when said retaining member is moved to said second position along said linear path.
Claim 3
Dependent Claim
40 words
The apparatus as claimed in claim 1, wherein said retaining member comprises a latch means for engaging said carrier substrate when said retaining member is moved to said second position to releasably fix the retaining member at said second position.
Claim 4
Dependent Claim
52 words
The apparatus as claimed in claim 1, wherein said carrier substrate has a guide groove extending therein in a direction that is parallel to said path, and said retaining member extends in said guide groove and is guided therein along said linear path when moved between said first and said second positions.
Claim 5
Dependent Claim
83 words
The apparatus as claimed in claim 3, wherein said carrier substrate has a window section extending therein that is open to said upper surface, the upper surface defines the bottom of said guide groove, and said retaining member has a pair of connecting pieces extending through said window section and slidably engaging said carrier substrate at respective edges defining said window section, said connecting pieces sliding along said edges respectively when said carrier substrate is moved between said first and said second positions.
Claim 6
Dependent Claim
79 words
The apparatus as claimed in claim 3, wherein said guide groove is defined between opposite side walls, one of said opposite said walls having an engaging section, and said retaining member comprises a resilient latch arm extending into said guide groove and engaging said one of said sidewalls, said resilient latch arm being biased to engage said engaging section when said retaining member is moved to said second position for releasably fixing said retaining member in said second position.
