Silicon wafer
Seed crystal
Semiconductors; Silicon wafer
Single crystal material used in crystal growing to set a pattern for the growth of material in which this pattern is reproduced.
Secondary flat
Semiconductors; Silicon wafer
A flat of length shorter than the primary orientation flat, whose position with respect to the primary orientation flat identifies the type and orientation of the wafer; minor flat.

Electrical resistivity
Semiconductors; Silicon wafer
The measure of difficulty with which charged carriers flow through a material; the reciprocal of conductivity.
Reclaim grade
Semiconductors; Silicon wafer
A lower quality wafer that has been used in manufacturing and then reclaimed (etched or polished) and subsequently used again in manufacturing.
