WebFeb 1, 2004 · Bottom antireflective coatings (BARC) are extensively used in optical lithography to minimize the effects of substrate reflectivity for critical dimension (CD) control. The reflection control for a film stack can be achieved using dielectric and/or organic BARC films. WebBottom anti-reflective coatings (BARC) provide a production proven solution to improve linearity, depth-of-focus, CD control and process latitudes of photoresists.

Bottom Anti-Reflective Coating for I-Line Lithography
WebN2 - Enhanced resolution of the structures can be achieved by employing the bottom anti-reflective coating (BARC) material in laser interference lithography process. The purpose of the BARC is to control the reflection of light at the surface of the wafer to minimize the effects caused by reflection. WebJun 1, 2003 · BARC (Bottom Anti-Reflective Coating) is used to minimize thin film interference effects such as swing curve, standing waves and resist notching in the … WebAug 1, 2000 · Implementation of a bottom anti-reflective coating (BARC) can reduce or eliminate line-width variations caused by interference and reflective notching. Therefore, the BARC is an essential technique in ArF excimer laser lithography with the practical resolution enhancement method. henry rothschild
