Abstract
The present invention provides an apparatus and a method of manufacturing that apparatus. More specifically, to a method of manufacturing probes for a stylus nanoprofilometer having a non-circular probe tip geometry and a method of measurement of semiconductor wafer features using the same. In one embodiment, the probe comprises an upper portion couplable to the stylus nanoprofilometer and a probative portion coupled to the upper portion. The probative portion has a cross section that is substantially thinner than a cross section of the upper portion. The probative portion further has a terminus distal the upper portion and a reentrant angle from the terminus to the upper portion.
