Abstract
Abstract A cantilever chip has a hold substrate and a film member bonded to the substrate. The film member has a rectangular cantilever portion and a triangular cantilever portion having an inner portion removed. These portions are formed by patterning. Each of the portions has an end fixed to the hold substrate, and a free end provided with a probe. The film member has an alignment end used as a mark to determine the position of the side end face of the hold substrate at the time of the film being bonded to the substrate. The alignment end is divided by notches into the cantilever portions.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A cantilever chip for use in a scanning probe microscope, comprising: a hold substrate having a side end face; and a film member bonded to the substrate and having: a cantilever portion, an alignment end used as a mark to determine the position of the side end face of the substrate with respect to the film member, and notches, scribed at a position overlying the side end face of said substrate, separating the cantilever portion from the alignment end, the cantilever portion having a projection projecting from the side end face of the substrate, a fixed end fixed to the substrate, and a free end with a probe.
Claim 2
Dependent Claim
108 words
A cantilever chip for use in a scanning probe microscope, comprising: a hold substrate having a side end face; and a film member bonded to the substrate and having: a cantilever portion, an alignment end used as a mark to determine the position of the side end face of the substrate with respect to the film member, and notches, scribed at a position overlying the side end face of said substrate, separating the cantilever portion from the alignment end, the cantilever portion having a projection projecting from the side end face of the substrate, a fixed end fixed to the substrate, and a free end with a probe.
Claim 3
Dependent Claim
31 words
