Abstract:
A method of mapping a surface of a semiconductor device with a stylus nanoprofilometer, comprising:mounting a probe in the stylus nanoprofilometer, the probe comprising:an upper portion couplable to a stylus nanoprofilometer; anda probative portion coupled to the upper portion and having a cross section that is substantially thinner than each cross section of the upper portion, the probative portion further having a predetermined length defined by a distal end coupled to the Lipper portion, and a terminus, the probative portion being tapered along the length such that a cross section at any point along the length is wider than a cross section of the distal end;contacting a surface of the semiconductor device with the terminus;recording dimensional coordinates of the terminus; andincrementing the probe in a first planar direction.
