Abstract

The focus of this paper is on the metrology of microstructures. Traditional Coordinate Measuring Machines (CMM) are limited to measuring holes of 300 m diameter. Smaller features and holes require thinner styli & novel probing technologies that can replace the probing system of the CMMs. In this paper, we focus on recent efforts by a number of researchers in developing new probing technologies that can measure micro features and holes of sizes as small as 50 m. We discuss technologies such as - electrical conductance detection from a vibrating probe to part, changes in resonant frequency of a vibrating probe upon contact, SPM type piezo-resistive strain gage probing, optical techniques etc. We also discuss a technique we are currently working on at the National Institute of Standards and Technology (NIST) to measure holes of the order of 100 m diameter. We will discuss 2D performance of this probe and also present ideas for extension of the probe to full 3D capability.
