Web16 jun. 2024 · Lithography printmaking is a planographic technique that was predicated on the immiscibility of water and oil at the time. The printing is done on a smooth-surfaced stone or metal plate. It was devised in 1796 by Alois Senefelder, a German playwright, and performer, and was first used primarily for orchestral music and maps. WebIn particular, we present results showing a reduction of etch-induced pattern shift by 12nm at wafer radius 147mm. Results show that asymmetry can be addressed by both, litho compensation and etch tuning, and bring on-product overlay down to the required level.
