Patent DE-4235702-A1 (DE)
Title: Substrate surface structuring - uses separate masks with partial patterns to expose separate photo sensitive layers to form a complete pattern as an etching mask
Inventor: NOELSCHER CHRISTOPH DR
IPC: G03F7/095
Filed: 1992-10-22
Abstract: To develop structures of a whole pattern on the substrate surface, at least one initial mask is used with a partial pattern and a second mask with a further partial pattern are used to expose two photo sensitive layers. The overlay of the two partial patterns gives the whole pattern. The interval between neighbouring structures in the two partial patterns is greater than the gap between neighbouring structures in the whole pattern. When the photo layer is exposed through the first mask, one photo layer structure is formed, and another structure is formed at the other layer through the second mask. The two structures together form an etching mask to form the whole pattern on the substrate surface. USE/ADVANTAGE - The substrate surface structure is formed for use in microelectronics or grids especially for surface wave filters or a semiconductor laser. The method gives a finer structure than can be achieved by conventional lithography.

Title: Identification pattern for picture tubes
Inventor: ROMMEL ERWIN
IPC: G09F7/16
Filed: 1993-09-10
Abstract: It is known to provide glass troughs (10) of picture tubes with identification patterns.
