Abstract
Sputter targets and methods of making same. The targets comprise B doped n-type Si. The targets may be made from single crystal boron doped p-type Si ingot made by the CZ method. Resistivities along the length of the crystal are measured, and blanks may be cut perpendicular to the ingot central axis at locations having resistivities of from about 1-20 ohm.cm. The blanks are then formed to acceptable shapes suitable for usage as sputter targets in PVD systems. No donor killing annealing is performed on the ingot or blanks.
