Abstract
As chipmakers continue to reduce feature sizes and shrink CDs on the wafer to meet customer needs, Cymer continues developing light sources that enable advanced lithography, and introducing innovations to improve productivity, wafer yield, and cost of ownership. In particular, the ETC controller provides improved spectral bandwidth and wavelength stability, which enables superior CD control and wafer yield for the chipmaker. This controller is a key technology in Cymer’s XLR 700ix and DynaPulseTM products. Last year we reported that the XLR 600ix incorporates new controller technology called ETC for improvements in spectral bandwidth and wavelength stability. The Authors will present metrics demonstrating the performance and stability of systems that have been installed at chipmaker sites over the last year.
