Abstract

A method for the determination of the deposited layer thickness distribution through the stack has been presented in a previous article [1]. We illustrate the validity of this model by considering the deposition of a Mo/B₄C design. This method is further improved to allow for the additional determination of roughness/diffusion through the multilayer stack. We show results of the analysis for a deposited small d-spacing W/B₄C design (d_avg=1.5nm) which give compelling evidence for the existence and determination of a minimum value of thickness that can be allowed in the design of the structure. From this analysis the multilayer was redesigned with a constraint on the minimum thickness allowed in the stack. We show successful results of the deposited redesigned structure. Finally, we show the influence of random layer thickness error on the resultant reflectivity.
