Abstract
Abstract A plurality of semiconductor integrated circuit devices are mounted on a film carrier. First electrical connecting sections and first electrical wiring sections for electrically connecting the first electrical connecting sections to the semiconductor integrated circuit devices are provided on the film carrier. Second and third electrical connecting sections and second electrical wiring sections are provided on a film-like probe for electrical characteristic test. The second electrical connecting sections are provided in position corresponding to the first electrical connecting sections of the film carrier. The third electrical connecting sections are used to supply electrical signals to the exterior or derive an electrical signal to the exterior and check the electrical signal. The second electrical wiring sections connects the second and third electrical connecting sections to each other. The film-like probe and the film carrier are superposed on each other so as to set the second electrical connecting sections of the filmlike probe into contact with the first electrical connecting sections of the film carrier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
294 words
A system for performing an electrical characteristic test of a plurality of semiconductor integrated circuit devices comprising: a film carrier on which the plurality of semiconductor integrated circuit devices are mounted; a plurality of groups of first electrical connecting sections formed on said film carrier, each group of first electrical connecting sections corresponding to one of the semiconductor integrated circuit devices; a plurality of groups of first electrical wiring sections formed on said film carrier, each group of first electrical wiring sections electrically connecting one of the semiconductor integrated circuit devices to the corresponding group of first electrical connecting sections; a film-like probe for supplying and deriving electrical signals necessary for the electrical characteristic test, said film-like probe including a film; a plurality of groups of second electrical connecting sections formed on the film-like probe, each group of second electrical connecting sections opposing a corresponding group of first electrical connecting sections on the film carrier when the film-like probe and film carrier are superimposed; a single group of third electrical connecting sections formed on the film-like probe for supplying or deriving electrical signals to or from the film-like probe; and a single group of second electrical wiring sections formed on said film-like probe for electrically connecting each group of second electrical connecting sections to the third electrical connecting sections, each second electrical wiring section electrically connecting one of the third electrical connecting sections to a plurality of the second electrical connecting sections; wherein the film-like probe is superimposed on the film carrier so as to bring each group of second electrical connecting sections of the film-like probe into contact with the corresponding group of first electrical connecting sections of the film carrier, thus effecting the electrical characteristic test of the semiconductor integrated circuit devices.
Claim 2
Independent Claim
294 words
A system for performing an electrical characteristic test of a plurality of semiconductor integrated circuit devices comprising: a film carrier on which the plurality of semiconductor integrated circuit devices are mounted; a plurality of groups of first electrical connecting sections formed on said film carrier, each group of first electrical connecting sections corresponding to one of the semiconductor integrated circuit devices; a plurality of groups of first electrical wiring sections formed on said film carrier, each group of first electrical wiring sections electrically connecting one of the semiconductor integrated circuit devices to the corresponding group of first electrical connecting sections; a film-like probe for supplying and deriving electrical signals necessary for the electrical characteristic test, said film-like probe including a film; a plurality of groups of second electrical connecting sections formed on the film-like probe, each group of second electrical connecting sections opposing a corresponding group of first electrical connecting sections on the film carrier when the film-like probe and film carrier are superimposed; a single group of third electrical connecting sections formed on the film-like probe for supplying or deriving electrical signals to or from the film-like probe; and a single group of second electrical wiring sections formed on said film-like probe for electrically connecting each group of second electrical connecting sections to the third electrical connecting sections, each second electrical wiring section electrically connecting one of the third electrical connecting sections to a plurality of the second electrical connecting sections; wherein the film-like probe is superimposed on the film carrier so as to bring each group of second electrical connecting sections of the film-like probe into contact with the corresponding group of first electrical connecting sections of the film carrier, thus effecting the electrical characteristic test of the semiconductor integrated circuit devices.
