Abstract : The patent relates to apparatus for masking selected portions of a curved surface to allow unit processing operations to be performed on the portions of the curved surface which are left exposed. In particular, the invention is a mechanical mask comprised of leaf-like projections having arcuate borders on the edges thereof. The arcuate borders are brought into engagement with a curved surface which is to have a processing operation performed thereon, thereby to mask that portion of the curved surface which is contacted by the arcuate borders of the leaf-like projections. The apparatus extends the use of a variety of prior art microelectronic processing techniques to situations wherein curved surfaces must be selectively patterned to produce a desired circuit or electronic device.
