6729945, May 4, 2004
Filed:

Mar 30, 2001
Appl. No.:

09/823722
Inventors:

Jeff Gasparitsch - Fremont CA
Robert Taff - Brentwood CA
Kenneth J. Bahng - Cupertino CA
Paul Stasiewicz - Fremont CA
Erik H. Engdahl - Livermore CA
Assignee:

Lam Research Corporation - Fremont CA
International Classification:

B24B 2108
US Classification:

451303, 451307
Abstract:

A platen for use in chemical mechanical planarization (CMP) systems is disclosed. The platen is arranged below a linear polishing pad and designed to apply a controlled fluid flow to the underside of the linear polishing pad. The platen includes a leading zone containing a first plurality of output holes. The leading zone is oriented more proximate to an upstream region of the linear polishing pad. The platen also includes a trailing zone containing a second plurality of output holes. The trailing zone is oriented more proximate to a downstream region of the linear polishing pad. The leading zone and the trailing zone are independently controlled and designed to output the controlled fluid flow independently from each of the first plurality of output holes and the second plurality of output holes.

US Patent:

8171876, May 8, 2012
Filed:

Apr 28, 2008
Appl. No.:

12/149133
Inventors:

Takumi Namekawa - Chigasaki, JP

Robert D. Taff - Pleasanton CA, US

Ralph D. Fox - Pleasanton CA, US
Assignee:

Ulvac, Inc. - Chigasaki-shi
International Classification:

B05C 5/02
US Classification:

118300, 118600, 118602, 118603, 118610, 222318, 137563, 137206, 137209, 347 84, 347 85, 347 89
Abstract:

The present invention provides applicators reducing generating bubble. Dispersion liquid is supplied while the pressure of a circulation tank on the delivery side is lower than the atmospheric pressure but higher than the pressure of the space in buffer tanks. The dispersion liquid in the discharge chambers is recovered while the pressure in a circulation tank serving as recovery destination is lower than the atmospheric pressure. Gas dissolution can be reduced because the dispersion liquid does not come into contact with gases at pressures higher than the atmospheric pressure and engulffing gas or deformation of solid microparticles can be avoided because no pump is used.
