Title: Lithographic method and system
Inventor: WHITE DONALD L
IPC: G03F1/00
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To enhance resolution of all features for a dark field image formed of radiation taken out from zero-order power by employing a mask having a transmission region including a pattern of very fine size selected such that a pattern image is not formed in the transmission region. SOLUTION: Light from an off-axis light source enters a mask including a non-image insertion mask feature and an off-axis angle is selected such that a zero-order light transmitted through the mask is not missed through the system. An image inserter 100 has a mask 110 and radiation 111 enters the mask 110 at an angle θC. The angle θC is selected such that a light 112 transmitted through the mask 110 is not captured by an optical system 120 on the downstream side of the mask 110. But a light 113 diffracted by the mask is captured by the image insertion optical system 120 on the downstream side. The image insertion optical system focuses the image and transfers it to an energy sensitive substance layer. Some diffraction orders 114 are not captured intentionally.
