Comprehensive 3-D Notching Simulator With Non-Planar Substrates
نویسندگان
چکیده
A comprehensive three-dimensional simulation model for non-planar substrate lithography is presented. Matching substrate as well as standing wave effects are examined. The projection printing is simulated using Hopkins' results and the exposure model is solved using spectral element discretizations of the nonlinear wave equation coupled with the rate equation for the photoactive compound concentrate evolution. The dissolution algorithm describing moving fronts has been modified to handle various topographies, thus yielding the final profiles. Results are presented for several test problems.

Three - dimensional photolithography simulator including rigorous nonplanar exposure simulation for off - axis illumination
Progress in today's semiconductor industry has been mainly achieved by decreasing the minimal feature size and increasing the complexity and thus the nonplanarity of the devices. Therefore lithography tools have to provide high resolution with a reasonably large depth of focus. Well-established methods to achieve both requirements are off-axis illumination techniques. As topography effects such...
