ABSTRACT
Deep trenches have been etched in crystalline silicon with polarization-controlled, variable curvature walls. Scan speeds of up to 10 mm/s have been demonstrated. A qualitative understanding of the etching process has been developed which is based on a local, melt-enhanced etch rate.

    Silicon mono-crystals have been bent thanks to a series of parallel superficial indentations on one of the largest faces of the crystals. This technique relies on irreversible compression of the crystal beneath and beside the indentations. This latter causes deformation with no need for external...
