Patent KR-20220111826-A (KR)
Inventor: KIM SE RA
IPC: G03F1/62
Filed: 2021-02-03
Abstract: The present invention directly bonds a pellicle film to an extreme ultraviolet photomask without an adhesive by using fusion bonding used for manufacturing a CMOS image sensor, hybrid bonding, or direct bonding performed in high vaccum cluster equipment when bonding heterogeneous substrates. Therefore, the present invention solves an outgassing problem occurring in a process due to the adhesive without a need of a pellicle frame. By connecting a plurality of micro pillars to the pellicle film, constantly maintaining an interval from the extreme ultraviolet photomask, and minimizing thickness of the pellicle film, extreme ultraviolet transmittance is increased. By preventing pleats and sagging of the pellicle film, the present invention increases a replacement period of pellicles and improves an exposure performance. Since a substrate on which the pellicle film is deposited is removed by an etching process in a state of directly bonding the pellicle film and the extreme ultraviolet photomask, the present invention simplifies a pellicle film manufacturing process and increases a manufacturing yield. Since the present invention uses a cleaning method with little damage to the photomask after physically removing a conventional pellicle film by replacing the pellicle film having a life cycle which is over, the present invention can extend a life cycle of the extreme ultraviolet photomask. Since the present invention bonds the pellicle film to each divided area of the extreme ultraviolet photomask by facilitating fine alignment bonding by the direct bonding, the present invention minimizes the pleats and the sagging of the pellicle film.
