    摘要: A lithography apparatus generates a tunable magnetic field to facilitate processing of photoresist. The lithography apparatus includes a chamber and a substrate stage in the chamber operable to hold a substrate. A magnetic module provides a magnetic field to the substrate on the substrate stage. The magnetic module is configured to provide the magnetic field in a tunable and alternating configuration with respect to its magnitude and frequency. The magnetic field is provided to have a gradient in magnitude along a Z-axis that is perpendicular to the substrate stage to cause magnetically-charged particles disposed over the substrate stage to move up and down along the Z-axis. The lithography apparatus also includes a radiation energy source and an objective lens configured to receive radiation energy from the radiation energy source and direct the radiation energy toward the substrate positioned on the substrate stage.

    摘要: A method for forming a semiconductor device includes forming a photoresist layer over a substrate and patterning the photoresist layer to form photoresist portions. A second layer is formed over the substrate in areas not covered by the photoresist portions and the photoresist portions are removed. After removing the photoresist portions, the second layer is used to modify the substrate to create at least a portion of the semiconductor device.

    摘要: A process of forming a fine pattern including forming a first photoresist layer over a first layer of a semiconductor device. Portions of the first photoresist layer are exposed causing a photochemical reaction therein. Prior to developing the first photoresist layer, a second photoresist layer is formed over the first photoresist layer, and wherein at least one of the first photoresist layer and second photoresist layer comprises a photo base generator.

    摘要: 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.
