Title: Correcting photo-mask patterns for use in photolithography for semiconductor mfr.
Inventor: TSUDAKA KEISUKE
IPC: G03F7/20
Filed: 1996-03-12
Abstract: The method involves deforming the mask pattern of a photomask to be used in a photolithographic step.

Patent DE-19650648-A1 (DE)
Inventor: SCHMIDT HANS-WEDDO
IPC: B01D63/10
Filed: 1996-12-06
Abstract: The invention relates to a wound module used for crossflow filtering operated by applying an almost constant transmembrane contact pressure, and to a method for producing said module. The wound module comprises a housing with a winding formed by membrane pockets and spacers connected thereto. Said winding has at least two cross-running radial canals. The filtrate is made to circulate in the same direction of flow as the filter fluid parallel to the membrane surface in such a way that an almost constant pressure differential prevails or can be regulated from when retentate is admitted until it is discharged. Besides homogenous filtrate flow over the entire membrane surface, local blockages or deposits are avoided by means of a covering layer on the membrane in the vicinity of the retentate entrance. The wound module is characterized by a high filtration capacity and a longer endurance time between required regenerations, e.g. by backwashing.

The channel region is doped with either B, BF2, P or As. A gate (17) is then formed in the channel region of the substrate after which a doped ion-implantation region is formed in the substrate on both sides of the gate.
