Abstract: A photomask assembly and method of forming the same are provided. The method includes: a portion of a buffer layer on a backside of a substrate of a photomask assembly may be removed prior to formation of one or more capping layers on the backside of the substrate. The one or more capping layers may be formed directly on the backside of the substrate where the buffer layer is removed from the substrate, and a hard mask layer may be formed directly on the one or more capping layers. The one or more capping layers may include a low-stress material to promote adhesion between the one or more capping layers and the substrate, and to reduce and/or minimize peeling and delamination of the capping layer(s) from the substrate. This may reduce the likelihood of damage to the pellicle layer and/or other components of the photomask assembly and/or may increase the yield of an exposure process in which the photomask assembly is used.

Title: Sieve jigger
Inventor: PUFAL ROLF HANS
IPC: B03B/
Filed: 2005-05-24
Abstract: The aim of the invention is to provide a sieve jigger comprising a sieved-product rocker that can be pivoted upwards and downwards, whose lifting displacement and/or lifting frequency can be controlled beyond previously accepted limits and which does not require vibration dampers that are subject to wear. To achieve this, the sieved-product rocker is operated by means of a lifting and braking cylinder comprising an integrated measuring device for the displacement of the cylinder piston and a working chamber, to which a hydraulic-oil supply and evacuation conduit is connected, said conduit containing an integrated proportional control valve. The lifting and braking cylinder interacts with the proportional control valve by means of a displacement sensor and a governor in order to control the displacement upwards and downwards and thus the lifting height and/or the lifting frequency of the rocker.
