摘要

Many existing metrology techniques are being applied to the measurement of microsystems. This area of metrology has many new challenges and for this reason it is necessary to have a greater understanding of the real capability of the metrology tool being used. Taylor Hobson has for many years been involved in the development of new metrology techniques and so when developing our latest technology, namely Coherence Correlation Interferometry, we saw the characterisation of this instrument as an important step in bringing the product to market. This paper describes the process of characterising this broadband interferometer by an independent body, NPL, including tests performed and presents some preliminary results.
