Abstract
The Scanning Microwave Probe (SMP) is emerging as an important broadband metrology tool for characterizing the materials and devices in the micron and sub-micron length scales in the frequency range of 10 MHz to 110 GHz. In this document we establish three important characteristics ofSMP: 1) the sensitivity of this tool to the materials property by showing data in the conductivity range of 0 to 2000 S/cm in a stratified medium )2 the breaking of the λ/2 barrier for spatial-resolution where we report measurement of 1υm spatially resolved features at the frequency of 4.6 GHz on SiGe sample and 3) detection of subsurface structures under 2 metal layers in an 8-layer CMOS IC with a measured 0.3% change in Q-factor at 1.8 GHz.Proceedings Title
