  • Method of stem-based drilling of ultrathin silicon nitride nanopores and nanopore arrays
    Patent number: 11338247
    Abstract: The invention concerns methods for preparing a nanoporous silicon nitride membrane comprising (i) ablating portions of at least one side of the membrane with an electron beam to reduce the thickness of the portions to between about 0.5 and 5 nanometers, and (ii) penetrating subportions of the ablated portions of the membrane with an electron beam to form nanopores having internal surfaces which are predominantly silicon rich compared to unablated portions of the membrane.
    Type: Grant
