US Patent:

6464081, Oct 15, 2002

Filed:

Mar 26, 2001

Appl. No.:

09/817805

Inventors:

David L. Nyseth - Plymouth MN
Dennis J. Krampotich - Shakopee MN

Assignee:

Entegris, Inc. - Chaska MN

International Classification:

B65D 8548

US Classification:

206711, 206454, 220801

Abstract:

A semiconductor wafer carrier has an enclosure with a door frame defining an opening for insertion and removal of wafers, a door for closing and sealing said opening, and separately formed door guides for controlling the interface between said door and the enclosure. In a preferred embodiment, the door guides each comprise a first body and a second body connected to each other by a web. Each body includes a door contacting portion and a door frame contacting portion. The door frame contacting portion has a sloped segment configured to a slidingly, progressively, and cooperatively engage the door frame to properly position the door within the door frame during closure with minimal particle generation by such contact. In this preferred embodiment, the guide is configured to be attached onto a corner edge of a door. In this arrangement, as the door is inserted into the door frame in the z-direction, the first and second bodies exert centering forces as needed in the x and y directions on corner portions of the door.

Assignee:

Entegris, Inc. - Chaska MN

International Classification:

B65D 8590

US Classification:

206711, 206454

Abstract:

A front-opening wafer transport module has a container portion with transparent shell and a central support structure which includes a machine interface exposed at the bottom of the module and integral wafer support columns extending upwardly in the container portion for supporting wafers. Additionally, the side walls of the shell have recessed portions with engagement members that cooperate with engagement members on removable handles. The handles utilize detents to lock into place in the recesses on the side walls of the carrier. Attachment of the handles to the side walls is accomplished without breaks between the interior and exterior of the module and without separate fastners.

6776289, Aug 17, 2004

Filed:

Mar 13, 2000

Appl. No.:

09/523745

Inventors:

David L. Nyseth - Plymouth MN

Assignee:

Entegris, Inc. - Chaska MN

International Classification:

B65D 8548

US Classification:

206711, 206454

Abstract:

A wafer carrier for transporting or holding wafers in a horizontal axially aligned arrangement has minimal four point regions of wafer support at the edge portion of the wafers. A preferred embodiment is an H-bar carrier with a plurality of slots defined by elongate wafer guides on the carrier sidewalls. Upwardly extended protrusions support the wafers with minimal contact with the carrier. The protrusions are sufficient in number and configuration to preclude contact with the top surface of the guides.

US Patent:

58164103, Oct 6, 1998

Filed:

May 24, 1996

Appl. No.:

8/647684

Inventors:

David L. Nyseth - Plymouth MN

Assignee:

Fluoroware, Inc. - Chaska MN

International Classification:

B65D 8530

US Classification:

206711

Abstract:

The present invention is a shipping container for safely storing articles such as semiconductor wafers. The shipping container has two sidewalls sealingly connected to two end walls to form a generally rectangular interior wafer confinement area. A top cover and a bottom cover are removably attached to the container to protect the wafers during shipping and storage and provide access to the wafers for processing. The wafers are securely held in place in the carrier by a cushioning means to prevent damage to the wafers. Furthermore, the wafers are locked into place to prevent contamination by the wafers generating particles in the wafer confinement area by rubbing against the carrier. The cushioning means for accommodating the flexing of the cover supports and suspends wafers in the wafer confinement area. The cushioning means extends from the top cover and has a plurality of wafer engaging edges.

Filed:

Jul 11, 1997

Appl. No.:

8/891645

Inventors:

David L. Nyseth - Plymouth MN
Dennis J. Krampotich - Shakopee MN

Assignee:

Fluoroware, Inc. - Chaska MN

International Classification:

B65D 8530

US Classification:

206710

Abstract:

A wafer container has an open front defined by a door receiving frame and a door sized for the door receiving frame. The door receiving frame has slots on opposite sides and the door utilizes latching linkages and lifting linkages cooperate to extend, lift, lower and retract the latching portions from the door into and out of latch receptacles on the door receiving frame. The door may also have passive wafer cushions or active wafer engaging arms which extend inwardly toward the wafers to secure said wafers when the door is in place. The latching linkages, lifting linkages, and where desired the retaining arms are linked to rotatable cammed members in the interiors if the door. The cammed member utilizes cammed surfaces configured to first extend the latching portions in a first direction into the latching receptacles and to then move the latching portions in a second direction normal to the first direction to pull the door inwardly and to seal the door to the container portion.
