Patent EP-0007668-A1 (EP)
Inventor: BAKER IAN MARTIN C O PHILIPS E
IPC: H01L25/04
Filed: 1979-07-17
Abstract: A group of infra-red radiation detector elements are manufactured from a body (21) of infra-red sensitive materials on an insulating substrate (22) using two masking steps which do not require critical alignment eeven with close spacing between the elements. A first masking layer (24; see Figure 10) e.g. of photoresist is formed on the upper surface of at least the body (21) to determine by a lift-off technique a metallization pattern (35,36; see Figure 13) on the body (21) and the substrate (22). A second masking layer (44) e.g. of photoresist is then provided to determine by ion-bombardment through windows (45) of this layer (44) the desired pattern of elements and their electrodes. The ion-bombardment permits removal of exposed areas of not just the body (21) and metallization pattern (35, 36) but also of a passivating layer on the body surfaces; a closely spaced group of elements and their electrodes can be obtained because the ion-bombardment results in steep sides without significant undercutting. 
     It is suggested that Figure 14 should accompany the Abstract when published.

Abstract: Method and apparatus for sign-making using dry transfer of letters from carrier sheets allows any of a number of different character sizes and row spacings to be provided. A carrier sheet (s) bearing characters of a desired size is positioned relative to a carriage (20) in dependence upon whether a row to be formed contains all upper case characters, or some or all lower-case characters. The carriage (20) is movable smoothly in a horizontal direction to allow any desired horizontal spacing of characters, but movable vertically only in discrete increments. A plurality of row spacing indicators (8,9) are positionable adjacent a sign blank (B) to afford a preview of how characters of a given size having a given spacing will appear on a sign blank.
