Overview

The SSM 5200 is an off-line metrology system that measures a variety of electrical oxide and dielectric characteristics on monitor wafers. It can measure capacitive effective thickness and equivalent oxide thickness of advanced gate dielectrics less than 1 nanometer thick with high precision. It also includes a wide range of current voltage (IV) measurements such as leakage current, TDDB, and SILC. The SSM 5200 uses a small elastic probe to form a temporary gate on the dielectric surface and an integrated pattern recognition system to locate scribe line test areas. The elastic probe has a diameter of less than 30 µm and does not damage the dielectric surface.
