A method and apparatus for a lift pin is described. In one embodiment, a lift pin head is described. The lift pin head includes a base member having a body made of a first material having a first coefficient of thermal expansion, and a tip disposed on the base member, the base member having a body made of a second material that is flexible at room temperature and having a second coefficient of thermal expansion, the first coefficient of thermal expansion being less than the second coefficient of thermal expansion.

A method and apparatus for a linear motion device is described. In one embodiment, linear motion device includes a housing having a bore formed therethrough along a longitudinal axis and at least two raceways formed at least partially in the housing having a plurality of bearing elements movably disposed therein. Each of the at least two raceways include a first channel disposed in a first radial plane relative to the longitudinal axis, and a second channel connected to the first channel and disposed in the first radial plane inward of the first channel, the second channel including a longitudinal slit allowing at least a portion of the plurality of bearing elements to extend into the bore.
摘要:
The present invention generally provides a high throughput substrate processing system that is used to form one or more regions of a solar cell device. In one configuration of a processing system, one or more solar cell passivating or dielectric layers are deposited and further processed within one or more processing chambers contained within the high throughput substrate processing system. The processing chambers may be, for example, plasma enhanced chemical vapor deposition (PECVD) chambers, low pressure chemical vapor deposition (LPCVD) chambers, atomic layer deposition (ALD) chambers, physical vapor deposition (PVD) or sputtering chambers, thermal processing chambers (e.g., RTA or RTO chambers), substrate reorientation chambers (e.g., flipping chambers) and/or other similar processing chambers.

A method and apparatus for processing a substrate is described. One embodiment of the invention provides an apparatus for forming thin films. The apparatus comprises a chamber defining an internal volume, a plasma source disposed within the internal volume, and at least one gas injection source disposed adjacent the plasma source within the internal volume, wherein the at least one gas injection source comprises a first channel and a second channel for delivering gases to the internal volume, the first channel delivering a gas at a first pressure or a first density and the second channel delivering a gas at a second pressure or a second density, the first pressure or the first density being different than the second pressure or the second density.
摘要:
A compact microwave downstream plasma system includes, within a significantly small portable housing unit, a power supply, a microwave generator, a non-linear waveguide, a circulator, a dummy load, a plasma applicator, and an igniter. The microwave generator supplies microwaves to the guide to the applicator. The guide includes several curved regions that allow for a more compact design. The applicator is configured to generate a plasma and output reactants that can be used to remove photoresist layers from a wafer within a process reactor.
