  • Publication number: 20080199282
    Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool). In one embodiment, the cluster tool is adapted to perform a track lithography process in which a photosensitive material is applied to a substrate, patterned in a stepper/scanner, and then removed in a developing process completed in the cluster tool. In one embodiment of the cluster tool, substrates are grouped together in groups of two or more for transfer or processing to improve system throughput, reduce the number of moves a robot has to make to transfer a batch of substrates between the processing chambers, and thus increase system reliability. Embodiments also provide for a method and apparatus that are used to increase the reliability of the substrate transfer process to reduce system down time.

  • Publication number: 20040020601
    Abstract: A series of modular apparatuses for processing substrates using a unique combinations of a substrate coating subsystem, a substrate curing subsystem and a PECVD-based capping subsystem. The individual subsystems are capable of being combined with one another for creating unique integrated substrate processing apparatuses that enable combined processing by the coating, curing and capping subsystems in an integrated and controlled environment, thus enabling the processing of substrates in an efficient manner, while minimizing the exposure of the substrates to an external environment and minimizing the condensation of vapors while the substrate is processed by the cure and capping subsystems.
