Appl. No.:

9/504719

Inventors:

Jeffrey M. Hoffman - Sierra Madre CA

Assignee:

Silicon Valley Group, Inc. - Ridgefield CT

International Classification:

G02B 1322
G02B 2710
G02B 1514

US Classification:

359663

Abstract:

The present invention provides an illumination system for varying the size of an illumination field incident to a scattering optical element. The illumination field is subsequently imaged to a reticle in a photolithographic process. The illumination system includes, in series along an optical axis of the illumination system, an optical source, a beam conditioner, a first optical integrator, a first or input collimating lens, a zoom array integrator (ZAI), a second or output collimating lens, the optical scattering element, a relay lens, and the reticle. The ZAI includes an assembly of fixed and moveable lens components arranged to vary the size of the illumination field throughout a zoom range of the ZAI while maintaining telecentric illumination at a substantially fixed numerical aperture. Illumination telecentricity and substantially fixed numerical apertures are maintained at both the scattering optical element and the reticle throughout the zoom range.

US Classification:

703 1

Abstract:

An optical design system generates a design state overview of a design of an optical system, the design state overview summarizing a current state and a target state of the design by describing a plurality of specifications for the optical system, the specification descriptions including target ranges for the specifications based on the target state of the design and further including current values for the specifications based on the current state of the design. The optical design system displays the design state overview. The optical design system updates the design state overview in response to the optical design system changing the current design for the optical system.
