PCT No. PCT/GB81/00222 Sec. 371 Date Jul. 8, 1982 Sec. 102(e) Date Jul. 8, 1982 PCT Filed Oct. 12, 1981 PCT Pub. No. WO82/01790 PCT Pub. Date May 27, 1982.In devices comprising closely spaced metallized regions deposited upon a dielectric substrate, in particular acoustic wave devices, electric fields may arise between the regions due to pyroelectic effects or acquired static charges during production or subsequently. These fields can cause damage by arcing or cracking of the substrate. The present method overcomes this problem by providing resistive links between such regions so that the fields do not arise. Preferably the links are of metallizing formed simultaneously with the metallized regions. Application to a SAW convolver is described in which the links are strips of metallizing (7,8,9). |
