Abstract: 1367836 Incandescent filament INTERNATIONAL BUSINESS MACHINES CORP 26 April 1972 [29 April 1971] 19277/72 Heading H1F An incandescent filament is made by forming a support layer on at least a portion of a surface of an insulative substrate, forming a pair of contacts on or in the surface of the substrate such that at least a portion of the support layer is positioned between the contacts, depositing a filament on the support layer so that the filament continuously extends between the contacts and removing the support layer to leave the filament supported by and connected to the contacts. A ceramic substrate 1 has a reflective coating 3 of Cr or W applied by vapour deposition or sputtering. The coating 3 is etched away to leave a serpentine configuration and a layer of glass 5 formed (Fig. 1C). Holes 7 and 9 are drilled and filled with copper to give posts 11 and 13. A layer of tungsten 15 is deposited and etched to give a serpentine configuration. A layer of copper 17 (Fig. 1H) is deposited on the lower face of substrate 1 and etched to provide contacts 21, 23 for the posts 11, 13. The glass layer 5 is removed by etching to give a suspended filament (Fig. 1J). In another embodiment, a serpentine configuration of copper (25, Fig. 3D, not shown) is provided and tungsten is preferentially deposited on it rather than on the glass layer to form a U-shaped crosssection filament (29, Fig. 3F, not shown), In an alternative embodiment (Figs. 4A to 4D, not shown) the substrate (31) has a trough which is temporarily filled while the filament is being formed. A 16-filament alphanumeric display cell may be made using this technique (Fig. 5, not shown). Alternatively an array of 5 x 7 incandescent filaments may be formed for use in an alphanumeric matrix (Fig. 6, not shown). The filaments are tapered towards the posts and bow upwardly from the substrate.
