Abstract: A Characterization Vehicle (CV) and a method for forming it which yields a gain in efficiency for IC yield ramp improvements by enabling faster learning cycles and diagnosis while reducing costs. A plurality of SF experiments are combined into a single full flow mask set with many inline testing points. Smaller pads are arranged in a way supporting testing of interleaved pad frames, parallel testing, and the usage of stacked test structures, or Devices Under Test (DUT's).

Abstract: A system and method for predicting yield of integrated circuits includes at least one type of characterization vehicle which incorporates at least one feature which is representative of at least one type of feature to be incorporated in the final integrated circuit product. The characterization vehicle is subjected to at least one of the process operations making up the fabrication cycle to be used in fabricating the integrated circuit product in order to produce a yield model. The yield model embodies a layout as defined by the characterization vehicle and preferably includes features which facilitate the gathering of electrical test data and testing of prototype sections at operating speeds. An extraction engine extracts predetermined layout attributes from a proposed product layout. Operating on the yield model, the extraction engine produces yield predictions as a function of layout attributes and broken down by layers or steps in the fabrication process.
