Abstract
Abstract An interconnect system (8') for providing electrical connection to bond pads on a semiconductor device (21) includes a socket (12) having a plurality of conductors (46) and a carrier assembly (40) mounted on the socket (12) for carrying a semiconductor device (21). The carrier assembly (40) includes a substrate (17) having a compliant membrane (20b) and a plurality of contact bumps (24) on a top surface of the compliant membrane (20b) for contacting bond pads on the semiconductor device (21) and a force applying mechanism (63). Compliant membrane (20b) is part of a thin film interconnect (20). Contact bumps (24) are connected electrically with conductors (46) by conductive traces (19) and contact pads (18) formed on the thin film interconnect (20). The force applying mechanism (63') applies pressure in making temporary electrical connection between contact bumps (24) and the bond pads of semiconductor device (21). The interconnection system (8') provides non-destructive interconnection to semiconductor device (21).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
195 words
A carrier assembly for carrying a semiconductor device, comprising: a base; a thin film interconnect extending over a top surface of said base; a plurality of contact bumps on a top surface of said thin film interconnect for contacting bond pads on the semiconductor device; a pair of posts extending from said base, each of said posts having a shaft having a first lateral dimension and a head having a second lateral dimension greater than said first lateral dimension; a lid positioned over said base; a rotary latch positioned over said lid, said rotary latch having a pair of openings through which said posts extend, each of said openings having a first portion in a first surface of said rotary latch and a second portion in a second surface of said rotary latch, said first and second surfaces being spaced vertically apart; a spring positioned between said lid and said rotary latch, said rotary latch applying force to said lid through said spring, whereby rotation of said rotary latch moves said heads from said first portion to said second portion to increase the force applied by said rotary latch to said lid through said spring.
Claim 2
Dependent Claim
195 words
A carrier assembly for carrying a semiconductor device, comprising: a base; a thin film interconnect extending over a top surface of said base; a plurality of contact bumps on a top surface of said thin film interconnect for contacting bond pads on the semiconductor device; a pair of posts extending from said base, each of said posts having a shaft having a first lateral dimension and a head having a second lateral dimension greater than said first lateral dimension; a lid positioned over said base; a rotary latch positioned over said lid, said rotary latch having a pair of openings through which said posts extend, each of said openings having a first portion in a first surface of said rotary latch and a second portion in a second surface of said rotary latch, said first and second surfaces being spaced vertically apart; a spring positioned between said lid and said rotary latch, said rotary latch applying force to said lid through said spring, whereby rotation of said rotary latch moves said heads from said first portion to said second portion to increase the force applied by said rotary latch to said lid through said spring.
Claim 3
Dependent Claim
58 words
The carrier assembly of claim 1 further comprising: signal traces on said top surface of said thin film interconnect electrically connected to said contact bumps; a conductive clip between a top surface of the semiconductor device and said lid for contacting said signal traces and the top surface of the semiconductor device for electrically biasing the semiconductor device.
Claim 4
Dependent Claim
23 words
The carrier assembly of claim 1 in which said lid has a pair of openings through which said shafts of said posts extend.
Claim 5
Dependent Claim
39 words
The carrier assembly of claim 1 in which said first portion is larger than the head of an associated one of said posts and said second portion is smaller than the head of the associated one of said posts.
Claim 6
Dependent Claim
37 words
The carrier assembly of claim 1 in which each of said openings has a third portion between said first and second portions, said third portion in a surface extending between said first surface and said second surface.
