US Patent:

8319410, Nov 27, 2012

Filed:

Dec 29, 2009

Appl. No.:

12/655347

Inventors:

Manuel A. Jerez - Roosevelt NY, US

Assignee:

Ion Technology Solutions, LLC - Mineola NY

International Classification:

H01J 27/00
H01J 19/42
H01J 19/44

US Classification:

313275, 313271, 313238, 313292, 313230, 3133591

Abstract:

The filament clamp assembly has a pair of bifurcated clamps to hold the connecting leads of a filament within a cavity of a cathode of a separate cathode assembly. The filament clamp assembly is mounted on the insulator block in self-aligning relation. The cathode assembly has a tungsten cathode with an internal cavity to receive the filament that is secured within a retainer shield made of one of tungsten, molybdenum and graphite by a threaded graphite cylindrical collar.

Appl. No.:

12/804277

Inventors:

Manuel A. Jerez - Roosevelt NY, US

International Classification:

H01J 27/08
H01J 61/04
H01J 1/88

US Classification:

313613, 313292, 250426

Abstract:

A cathode sub-assembly is comprised of a retainer, a cathode and a collar, each of which has smooth unthreaded surfaces that slidably engage each other. A shield serves to hold the sub-assembly in a support plate. The cathode projects from the sub-assembly into an arc chamber with a tortuous path created therebetween for passage of a plasma flow.

Appl. No.:

14/222147

Inventors:

MANUEL A. JEREZ - ROOSEVELT NY, US
CARLOS F. M. BORGES - ROSLYN NY, US

International Classification:

H01J 37/04
H05H 1/34

Abstract:

The plasma arc chamber is made in part of a one piece base fabricated from 95.95% pure tungsten having four rigid walls defining a rectangular central opening. A bottom plate closes the bottom of the base and a cover with a slit for the passage of an ion beam closes the top of the base. Liners are fitted into the bottom plate, the top of base and against the four walls of the base.

Inventors:

Manuel A. Jerez - Roosevelt NY, US
Carlos F.M. Borges - Roslyn NY, US

International Classification:

H01J 37/30
H01J 37/317

Abstract:

The extraction electrode has a pair of sub-assemblies that define a gap. Each sub-assembly has a suppression plate and ground plate secured together in spaced relation by pairs of insulating assemblies. A plate assembly extends perpendicularly from the ground plate. The gap between the subassemblies is set by tabs on a centering fixture extension.

International Classification:

G21K 1/00
H01J 37/317

US Classification:

25049221, 2505151

Abstract:

The source bushing assembly has a source bushing having an internal vacuum side and an external atmosphere side, a first shield of annular shape disposed at one end of the source bushing in spaced concentric relation to reduce formation of an electrically conductive coating on the source bushing, a second shield of annular shape disposed at an opposite end of the source bushing in spaced concentric relation to prevent arcing on the source bushing and an internally disposed concentric X-ray shield.

Inventors:

Manuel A. Jerez - Roosevelt NY, US
Carlos F. Borges - Roslyn Estates NY, US

International Classification:

H01J 27/08
H01J 1/88
H01J 7/26

US Classification:

313 36, 31323141, 313292

Abstract:

The support and electrode assemblies of the ion implanter are cooled by circulating a coolant through these parts during operation. The support for the arc chamber includes a one piece block of aluminum through which coolant passes and a hollow rectangular post on which the arc chamber sits with a space therebetween.
