Abstract:
1. An apparatus for forming a tape-based, epitaxial lift-off film for at least one of a solar device, a semiconductor device, and an electronic device, comprising: a first end; a second end; a tape supply section proximate the first end, the tape supply section providing an unloaded support tape; a lamination section for receiving the unloaded support tape and a plurality of substrates, each substrate containing an epitaxial film thereon, the lamination section adhering the substrates to the unloaded support tape to form a loaded support tape; and an ELO etch section proximate the second end and comprising a pressure system, wherein the pressure system comprises a static wedge, wherein the static wedge is configured to progressively apply pressure on said loaded support tape such that pressure is applied progressively towards a center-line of said loaded support tape when passing through said ELO etch section, the ELO etch section removing the substrates from the loaded support tape, while leaving the epitaxial film on the loaded support tape.
