Appl. No.:

9/346867

Inventors:

Gordon Haggott Beckhart - Colorado Springs CO
Patrick Rooney Conarro - Cascade CO
Kevin James Harrell - Woodland Park CO
Michael Charles Krause - Colorado Springs CO

Assignee:

MicroTool, Inc. - Colorado Springs CO

International Classification:

G01B 1100

US Classification:

25055933

Abstract:

A tool for aligning a robot arm to a cassette for holding semiconductor wafers has a housing having a slot one position for holding a semiconductor wafer. A z-axis non-intrusive detector is attached to the housing and senses if the semiconductor wafer is aligned in the slot one position. An indicator is connected to the z-axis detector and provides a signal indicating when the semiconductor wafer is aligned in the slot one position.

International Classification:

B65B 2900
B65B 3102
B65B 6308

US Classification:

53400

Abstract:

A method for protecting substrates used in the manufacture of semiconductors, memory products, and other electronic devices from the effects of moisture during transport and storage is disclosed. This method involves the use of a cassette or box made from polycarbonate or another material having similar hydroscopic properties, treating the cassette or box to reduce its moisture content, and surrounding the cassette or box, and the substrates held therein, with a moisture barrier. This results in a package which will keep the substrates dry and eliminates the need for a separate desiccant within the package.
