Appl. No.:

11/455996
Inventors:

Birk Lee - Atherton CA, US
Assignee:

CREDENCE SYSTEMS CORPORATION - Milpitas CA
International Classification:

G01R 31/02
US Classification:

324760
Abstract:

A micro-spray cooling system beneficial for use in testers of electrically stimulated integrated circuit chips is disclosed. The system includes micro-spray heads disposed about a probe head, which provide a coolant flow onto the IC. A flow inducing injector is provided that directs a fluid jet onto zones where stagnation of the coolant flow is present. This reduces or eliminates any stagnation points and enhance temperature uniformity over the area of the IC.
