Patent ID: 7141995

Claim:
A semiconductor manufacturing device comprising: a wafer stage where a wafer is mounted; and a prober that performs, within a first cycle, both of (i) trimming in a first chip forming region, in which trimming has not yet been performed, wherein the first chip forming region is included in a plurality of chip forming regions of the wafer and (ii) inspecting a second chip forming region included in the plurality of chip forming regions, wherein the second chip forming region was previously trimmed, by causing a plurality of probing needles to simultaneously contact pads on the first chip forming region and the second chip forming region, wherein the wafer stage is transferred by the prober before the first cycle ends and after both of the trimming and the inspecting are completed, wherein the prober is then allowed to perform, within a second cycle, following the first cycle, both of (i) trimming a third chip forming region included in the plurality of chip forming regions and (ii) inspecting the first chip forming region, wherein trimming has been performed in the first chip forming region, by causing the plurality of probing needles to simultaneously contact pads on the third chip forming region and the first chip forming region.
