  • METHOD FOR INSPECTING PATTERN DEFECTS
    Publication number: 20250093278
    Abstract: In a method for inspecting pattern defects, a plurality of patterns are formed over an underlying layer. The plurality of patterns are electrically isolated from each other. A part of the plurality of patterns are scanned with an electron beam to charge the plurality of patterns. An intensity of secondary electrons emitted from the scanned part of the plurality of patterns is obtained. One or more of the plurality of patterns that show an intensity of the secondary electrons different from others of the plurality of patterns are searched.

  • Compositions and methods of tumor treatment utilizing nanoparticles
    Patent number: 10016365
    Abstract: The present invention is directed to a method for treating cancer intraperitoneally in a subject. The method comprises administering to said subject in need thereof an anti-cancer agent encapsulated in nanoparticles wherein nanoparticles are characterized to slowly release anti-cancer agent in a timely fashion that allows efficient killing of tumor cells. The nanoparticles described herein are characterized to slowly release anti-cancer agent at a rate of 30% or less per 24 hours based on in vitro drug dissolution study.
