Abstract

Monocrystalline semi-conductor discs for use in the manufacture of semi-conductor devices or as seed crystals are produced from a monocrystalline rod of uniform diameter having its longitudinal axis orientated in a crystallographic direction such that planes along which cleavage can readily occur are perpendicular to the axis. The rod is notched at intervals along its length and thereafter cleaved at the notches by application of lateral pressure and/or tension. For instance a germanium or silicon rod grown from a melt with the 111, 110, 221 or 112 crystallographic direction lying along its axis is notched by a diamond point or edge and cleaved by a high quality steel point applied obliquely to the rod at the notches. If the resulting discs are kept in an inert atmosphere they may be used in semi-conductor device fabrication without further clearing or etching. Otherwise only a light etching is required to remove oxide films. Particularly smooth uniform surfaces are obtained if the cross section of the rod exceeds the square of the thickness of the discs.
