1. A method comprising:
- forming, using a first process applied to a first surface of a substrate, a slot through the substrate having the first substrate surface and a second substrate surface such that the slot has a tapered portion at each of its ends; and
,removing, from the second substrate surface, at least part of the tapered portions of the slot using means for delivering abrasive particles to lengthen the slot and change its shape at the slot ends, wherein the forming and the removing configure the slot with a generally uniform minimum width measured orthogonally to a long axis of the slot.

Abstract
The described embodiments relate to methods and systems of forming slots in a substrate. One exemplary embodiment forms a feature into a substrate having a first substrate surface and a second substrate surface, and moves a sand drill nozzle along the substrate to remove substrate material sufficient to form, in combination with said forming, a slot through the substrate.

11. A method comprising:
-
forming, using a first process, a slot through a substrate having a first substrate surface and a second substrate surface such that the slot has a tapered portion at each of its ends; and
,removing at least part of the tapered portion of the slot by moving a nozzle of a sand drill for delivering abrasive particles along a longitudinal axis of the substrate at a speed that is proportional to an elevational thickness of substrate material between the second substrate surface and a tapered elevational profile of the tapered portion to lengthen the slot and change its shape at the slot ends. - View Dependent Claims (12)
