High power tungsten halogen lamp lifetime improvement through j-hook design

A lamp, comprising:

• a bulb;
• a filament;
• and
• a plurality of filament supports disposed in spaced-apart relation to the filament, the plurality of filament supports comprising at least a first filament support and a second filament support, each of the filament supports further comprising a hook support and a hook, wherein the hook comprises:
• a connector, the connector being configured to fasten the hook to the hook support;
• a first vertical portion, the first vertical portion extending from the connector toward the filament;
• and
• a second vertical portion, the second vertical portion extending toward the hook support, wherein the second vertical portion of the first filament support has a length between 60% and 100% of the length of the first vertical portion of the first filament support;
• and
• wherein the first vertical portion of the first filament support is longer than the first vertical portion of the second filament support.

An epitaxial processing apparatus, the apparatus comprising:

• a processing chamber, the processing chamber defined by an upper dome and a lower dome;
• a susceptor within the processing chamber, the susceptor being configured to support a substrate;
• a plurality of lamps positioned over the upper dome and positioned under the lower dome, the lamps comprising:
• a bulb;
• a filament;
• and
• a plurality of filament supports disposed in spaced-apart relation to the filament, the plurality of filament supports comprising at least a first filament support and a second filament support, each of the filament supports further comprising a hook support and a hook, wherein the hook comprises:
• a connector, the connector being configured to fasten the hook to the hook support;
• a first vertical portion, the first vertical portion extending from the connector toward the filament;
• and
• a second vertical portion, the second vertical portion extending toward the hook support, wherein the second vertical portion of the first filament support has a length between 60% and 100% of the length of the first vertical portion of the first filament support;
• and
• wherein the first vertical portion of the first filament support is longer than the first vertical portion of the second filament support.
