Abstract:
Embodiments of the invention include a load lock chamber, a processing system having a load lock chamber and a method for transferring substrates between atmospheric and vacuum environments. In one embodiment, the method includes maintaining a processed substrate within a transfer cavity formed in a chamber body for two venting cycles. In another embodiment, the method includes transferring a substrate from a transfer cavity to a heating cavity formed in the chamber body, and heating the substrate in the heating cavity. In another embodiment, a load lock chamber includes a chamber body having substrate support disposed in a transfer cavity. The substrate support is movable between a first elevation and a second elevation. A plurality of grooves are formed in at least one of a ceiling or floor of the transfer cavity and configured to receive at least a portion of the substrate support when located in the second elevation.

Abstract:
The present invention generally provides a batch substrate processing system, or cluster tool, for in-situ processing of a film stack used to form regions of a solar cell device. In one configuration, the film stack formed on each of the substrates in the batch contains one or more silicon-containing layers and one or more metal layers that are deposited and further processed within the various chambers contained in the substrate processing system. The processing chambers may be, for example, physical vapor deposition (PVD) or sputtering chambers, plasma enhanced chemical vapor deposition (PECVD) chambers, low pressure chemical vapor deposition (LPCVD) chambers, hot wire chemical vapor deposition (HWCVD) chambers, plasma nitridation (DPN) chambers, ion implant/doping chambers, atomic layer deposition (ALD) chambers, plasma etching chambers, annealing chambers, rapid thermal oxidation (RTO) chambers, rapid thermal annealing (RTA) chambers, substrate reorientation chambers, laser annealing chambers, and/or plasma cleaning stations. In one embodiment, a batch of solar cell substrates is simultaneously transferred in a vacuum or inert environment to prevent contamination from affecting the solar cell formation process.
Abstract:
A method of processing a substrate that enables the amount removed of a surface damaged layer to be controlled easily, and enable a decrease in wiring reliability to be prevented. A surface damaged layer having a reduced carbon concentration of a carbon-containing low dielectric constant insulating film on a substrate is exposed to an atmosphere of a mixed gas containing ammonia and hydrogen fluoride under a predetermined pressure. The surface damaged layer that has been exposed to the atmosphere of the mixed gas is heated to a predetermined temperature.
Abstract:
There is described a wafer processing system for thinned wafers that are easily broken during handling. The system protects against breakage during handling and provides for temperature controls during processing.
Abstract:
Methods correcting wafer position error are provided. The methods involve measuring wafer position error on a robot, e.g. a dual side-by-side end effector robot, during transfer to an intermediate station. This measurement data is then used by a second robot to perform wafer pick moves from the intermediate station with corrections to center the wafer. Wafer position correction may be performed at only one location during the transfer process. Also provided are systems and apparatuses for transferring wafers using an intermediate station.
Abstract:
A new apparatus for processing substrates is disclosed. A multi-level load lock chamber having four environmentally isolated chambers interfaces with a transfer chamber that has a robotic assembly. The robotic assembly has two arms that each can move horizontally as the robotic assembly rotates about its axis. The arms can reach into the isolated chambers of the load lock to receive substrates from the bottom isolated chambers, transport the substrates to process chambers, and then place the substrates in the upper chambers. The isolated chambers in the load lock chamber may have a pivotably attached lid that may be opened to access the inside of the isolated chambers.
Abstract:
A gas-tight module capable of preventing the collapse of a pattern formed on a principal surface of a substrate, without lowering throughput. A load lock module of a substrate processing system includes a transfer arm, a chamber, and a load lock module exhaust system. A plate-like member is disposed in the chamber such as to face the principal surface of a wafer transferred into the chamber. An exhaust passage isolated from the remaining space in the chamber is defined by the wafer and the plate-like member at a location right above the principal surface of the wafer. The sectional area of the exhaust passage is smaller than that of the remaining space in the chamber.
