Laser-induced removal of particles from surfaces was demonstrated. Such “laser cleaning” can be performed on the bare contaminated surface or with additional micronthickness liquid film coverage on the surface. With the latter “steam laser clea

Pulsed-laser-induced removal of particles from surfaces is a new cleaning technique. This laser cleaning can be performed on dry surfaces as well as on wet surfaces with a micron-thick liquid film during pulsed laser irradiation to provide enhanced r

‘Liquid Film Enhanced Laser Cleaning” is a technique to remove particulate contamination from surfaces. A thin liquid film deposited onto the contaminated surface is flood irradiated with a short laser pulse. The resulting sudden evaporation of t

Following the trends in the semiconductor technology to higher density and smaller dimensions the light-optical tools get serious technical problems to solve the requirements on resolution, depth of focus and overlay. Besides exposure tools using DUV

Laser cleaning was demonstrated to be a new, promising approach to efficiently remove particulate contamination of micron and submicron size from wafer surfaces as well as from the surface and trenches of thin silicon membrane stencil masks as used f

Mix-and-match lithography between Electron Proximity Printing (EBP) and optical lithography was demonstrated in processing nine levels of a 1Mbit device up to first metallization. High overlay accuracy was achieved. For the first time we produced a l
