摘要： A nanophotolithography mask includes a layer of an electrically conductive optically opaque material deposited on a mask substrate in which regular arrays of sub-wavelength apertures are formed. The plasmonic excitation in the layer perforated with the sub-wavelength apertures arrays under the light incident on the mask produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer when propagated to the same. The fill-factor of the mask, i.e., the ratio of the total apertures area to the total mask area, may lead to a significant increase in mask manufacturing throughput by FIB or electron beam “writing”. The mask demonstrates the defect resiliency and ability to imprint coherent clear features of nano dimensions and shapes on the wafers for integrated circuits design.

摘要： A stepper system for ultra-high resolution nano-lithography employs a photolithographic mask which includes a layer of an electrically conductive optically opaque material in which periodic arrays of sub-wavelength apertures are formed. The plasmonic excitation in the photolithographic mask exposed to the light of the wavelength in the range of 197 nm-248 nm, produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer. The stepper system demonstrates the resiliency to the mask defects and ability to imprint coherent clear features of nano dimensions (45 nm-500 nm) and various shapes on the wafers for integrated circuits design. The stepper system may be adjusted to image the plane of the highest plasmonic field exiting the mask.

摘要： A nutritional medium for enabling the growth, maintenance and transport of cells in a container of virtually any size or shape, including a substantially flat, multi-well plastic plate. The nutritional medium is capable of assuming a substantially liquid state above a first temperature and a substantially solid state below a second temperature. Both the first and second temperatures are generally compatible with the survival of the cells in the container. The cells are covered with the medium while the medium is in a substantially liquid state, and the temperature of the medium is then reduced to a temperature at which the medium assumes a substantially solid state. The medium is maintained in a substantially solid state while the cells are transported. Upon arrival at the end user, the temperature of the medium is increased to a temperature at which the medium assumes a substantially liquid state. Following a change to fresh maintenance medium, the cells in the container are ready for immediate use.
