Abstract: A lithographic patterning method includes forming a multi-layer patterning material film stack on a semiconductor substrate, the patterning material film stack including a resist layer formed over one or more additional layers, and forming a metal-containing top coat over the resist layer. The method further includes exposing the multi-layer patterning material film stack to patterning radiation through the metal-containing top coat to form a desired pattern in the resist layer, removing the metal-containing top coat, developing the pattern formed in the resist layer, etching at least one underlying layer in accordance with the developed pattern, and removing remaining portions of the resist layer. The metal-containing top coat can be formed, for example, by atomic layer deposition or spin-on deposition over the resist layer, or by self-segregation from the resist layer.

Abstract: Methods for determining unintentional exposure dose such as flare or out-of-band radiation of a lithography tool are provided. The methods generally include performing a series of open frame exposures with the lithography tool on a substrate having a photoresist therein to produce a primary array of controlled exposure dose blocks in the photoresist. Secondary exposure blocks are embedded within the primary array. The resultant open frame images are scanned with oblique light and the light scattered from the substrate surface captured. A haze map is created from a background signal of the captured scattered light data and converted to a graphical image file. Analyzing the graphical image file can be used to correlate any localized changes in the effective dose of the primary exposure array to the impact of secondary exposure blocks to characterize flare or out-of-band radiation associated with the exposure dose.
