Abstract:
PROBLEM TO BE SOLVED: To minimize the contamination and defects due to the maintenance by making the time shortest for the maintenance of a machine part arranged in an internal space of the machine. SOLUTION: This invention relates to a method of maintaining the machine part arranged in an internal space 11 of a machine 1. The internal space 11 is kept at a first pressure (P vac ) and is separated from an environment having a second pressure (P env ) via a load lock (LL). The method comprises transporting a machine part (32, WT) via the load lock (LL) out of the internal space 11, and transporting one of the maintained machine part and a separate replacement machine part via the load lock (LL) into the internal space 11.

Abstract:
PROBLEM TO BE SOLVED: To provide a particle inspection system and a particle inspection method for inspecting particles present on the top surface of a substrate. SOLUTION: A photolithography apparatus transfers a pattern from a patterning device to a substrate, and includes the particle inspection system for inspecting the particles present on the top surface of the substrate. The particle inspection system incorporates a radiation source for the radiation generation, illumination optical system guiding the radiation generated by the radiation source to a detection area at the top surface of the substrate, detection optical system receiving the radiation from the inspection area at the top surface of the substrate, and a detector coupled to the inspection optical system for generating at least one measurement signal. This apparatus further incorporates a processing unit to determine the height of a particle based on at least one measurement signal and generate a height excess signal if the height exceeds a threshold value.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection assembly comprising: a substrate handler provided with a handler chamber in which at least two load locks for transferring a substrate between a first environment and a second environment are provided, the second environment has a lower pressure than the first environment, and further the second environment is superior; and a lithographic projection apparatus comprising a projection chamber. SOLUTION: The handler chamber and the projection chamber connect with each other through, on one hand, a loading position so that the substrate enters from the handler chamber the projection chamber, and on the other hand, an unloading position for taking out the substrate from the projection chamber to the handler chamber. The handler chamber is provided with a pretreatment means for pretreating the substrate, and a transporting means having a constitution in which the substrate is transferred from the load lock to the pretreatment means, and transferred from the pretreatment means to the loading position, and further transferred from the unloading position to the load lock.

Abstract:
The invention relates to a lithographic projection assembly, having at least two load locks for transferring substrates between a first environment and a lower pressure second environment, a substrate handler with a handler chamber within the second environment and a lithographic projection apparatus including a projection chamber. The handler chamber and the projection chamber communicate via a load position for entering a substrate from the handler chanter into the projection chamber and an unload position for removing the substrate from the projection chamber into the handler chamber. The handler chamber also includes pre-processing means for pre-processing of the substrates and transport means for transferring substrates between the load locks and pre-processing means.
Abstract:
A method of and apparatus for maintaining a machine part arranged in an interior space of a machine, where the interior space is kept at a first pressure and is separated from an environment having a second pressure via a load lock. The method includes transporting a machine part via the load lock out of the interior space and transporting via the load lock into the interior space one of the maintained machine part and a separate replacement machine part.
