摘要:
Disclosed is an objective lens adapted for use in liquid immersion photolithography and a method for making such a lens. In one example, the objective lens has multiple lens elements, one of which includes a transparent substrate and a layer of anti-corrosion coating (ACC). The ACC is formed proximate to the transparent substrate and is positioned between a liquid used during the liquid immersion photolithography and the transparent substrate to protect the transparent substrate from the liquid.

A lens cleaning module for a lithography system having an exposure apparatus including an objective lens is disclosed. The lens cleaning module includes a scanning stage for supporting a wafer beneath the objective lens. A cleaning module is provided adjacent to the scanning stage for cleaning the objective lens in a non-manual cleaning process.

A megasonic immersion lithography exposure apparatus and method for substantially eliminating microbubbles from an exposure liquid in immersion lithography is disclosed. The apparatus includes an optical system for projecting light through a mask and onto a wafer.An optical transfer chamber is provided adjacent to the optical system for containing an exposure liquid. At least one megasonic plate operably engages the optical transfer chamber for inducing sonic waves in and eliminating microbubbles from the exposure liquid.

Disclosed is an objective lens adapted for use in liquid immersion photolithography and a method for making such a lens. In one example, the objective lens has multiple lens elements, one of which includes a transparent substrate and a layer of protective coating (PC). The PC is formed proximate to the transparent substrate and is positioned between a liquid used during the liquid immersion photolithography and the transparent substrate to protect the transparent substrate from the liquid.

A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.
摘要:
The invention comprises methods and devices of forecasting future computational needs of an application based on input load, where the application comprises a plurality of processes executed on a plurality of computing devices. The method of the invention proceeds by monitoring at least a computational load characteristic of at least a first process executed on a first computing device and a second process executed on a second computing device. A mathematical relationship between input load and the computational load characteristic is established, and future computational needs are forecasted based on the established mathematical relationship.
