Abstract

Wafer test control and methodologies are provided for resuming the probing of a wafer, in connection with random, distributed or statistical wafer probing. The resumption of testing may occur after an interruption of a previous probe of the wafer and removal of the wafer from a testing chuck. Parameter settings are retained in addition to probe results from the previous wafer probe session in order to construct a resume probe map according to applicable probing rules and conditions. Wafer probing may be restarted according to the resume probe map.
