Title: Integrated circuit wiring structure prodn. - by electron lithography, three anodising stages under different conditions and removal of oxide
Inventor: HIEKE EDUARD DIPL ING DR
IPC: H01L21/768
Filed: 1979-01-29
Abstract: Prodn. of wiring structures for integrated circuits involves electron beam lithography and anodisation of metal layers. A lacquer (4) sensitive to electron radiation is used in the exposure of areas (5) of the preanodised surface (2,3) of the substrate (1). After lithography, the exposed areas of metal oxide (3,5) are reanodised to form a non-porous (barrier) metal oxide (6). After removing the lacquer (4), a third anodisation stage is carried out, so that the exposed metal oxide film (2,3) is converted to a porous oxide film (7) over its entire surface. Finally, the anodised films (3,6,7) are removed. The entire process is reliable and can be automated. It is possible to produce 2-layer wiring.
