Abstract

Continually shrinking features sizes coupled with tighter tolerances for critical dimensions and feature placement necessitate development of new metrology tools that can meet the demand for more precision and accuracy during the measurement process. With this in mind Leica Microsystems has developed a next general metrology system that is capable of fulfilling both the feature placement and critical dimension metrology requirements. This paper contains a brief description of the new system hardware and design changes incorporated into the Leica LMS IPRO2 as well as recent measurement data indicative of initial tool performance.
