  • Patent number: 7935547
    Abstract: A method for patterning a layer on a semiconductor substrate includes forming a layer of a semiconductor substrate and exposing the layer to light. The light travels through a second pellicle that is manufactured by a method that includes determining a first transmission of a first light through a first pellicle, wherein the first light is normal to the first pellicle, determining a second transmission of a second light through the first pellicle, wherein the second light is not normal to the first pellicle, and modifying the first pellicle to form a second pellicle using the first and second transmission.

  • Patent number: 7879727
    Abstract: A method of fabricating a semiconductor device including depositing a hardmask layer on a layer of the semiconductor device, selectively etching a pattern of continuous lines in the hardmask layer, depositing an antireflective coating over remaining portions of the hardmask layer, depositing a photoresist layer on the antireflective coating, patterning the photoresist layer with a plurality of isolation trenches via a lithography process, each of the isolation trenches extending perpendicular to and crossing portions of at least one of the continuous lines of the underlying hardmask layer, and with each isolation trench having an initial width.

  • Publication number: 20090209097
    Abstract: A method of forming interconnects includes etching a first set of openings in a hard mask using a first photo resist layer with a first pattern of openings as a first etch mask, and etching a second set of openings in the hard mask using a second photo resist layer with a second pattern of openings as a second etch mask. The method includes shrinking the openings in at least one of the first pattern and the second pattern prior to etching the openings in the hard mask.
