Abstract:
A wafer bonding apparatus is provided. The wafer bonding apparatus includes a first wafer chuck, a second wafer chuck, and a plurality of bonding pins. The first wafer chuck is configured to hold a first wafer. The second wafer chuck is configured to hold a second wafer. The bonding pins are accommodated in the first wafer chuck and configured to be movable through the first wafer chuck to apply pressure to bend the first wafer, thereby causing bonding contact of the first wafer and the second wafer.
Abstract:
An extreme ultra violet (EUV) lithography apparatus includes a light source that generates an EUV light beam, a scanner that receives the light from a junction with the light source and directs the light to a reticle stage, and a debris catcher disposed on a EUV beam path between the light source and the scanner. The debris catcher includes a network membrane including a plurality of nano-fibers.
Abstract:
A lithography apparatus includes a plurality reticle edge masking assemblies (REMAs), wherein each REMA of the plurality of REMAs is positioned to receive one of a plurality of light beams, and each REMA of the plurality of REMAs comprises a movable slit for passing the received light beam therethrough. The lithography apparatus includes a controller for controlling a speed of the movable slit based on a size of the movable slit, an intensity of the one or more collimated light beams, or a material to be patterned. The lithography apparatus further includes a single mask having a single pattern, wherein the mask is configured to receive light from every REMA of the plurality of REMAs. The lithography apparatus includes a projection lens configured to receive light transmitted through the single mask, wherein the lithography apparatus is configured to introduce an immersion liquid into a space adjacent to the projection lens.
