  • Patent number: 6746823
    Abstract: A process of fabricating a non-gap 3-D microstructure array mold core comprises a first step in which a buffer layer is coated on a substrate. A photomask layer is then coated of the buffer layer. A pattern is subsequently formed on the photomask by photo-lithography. The patterned photomask layer is subjected to a reflow by which a microstructure array is formed on the photomask layer. The microstructure array is coated with a metal conductive layer. The microgaps of the microstructure array are eliminated by an electrocasting layer which is coated on the microstructure array. The non-gap microstructure array mold core so fabricated is made into a metal molding tool by microinjection molding or microthermo-pressure molding.

  • Patent number: 6656668
    Abstract: A process method of using excimer laser for forming micro spherical and non-spherical polymeric structure array includes a photomask which has a selected curved pattern formed thereon. The curved pattern has non-constant widths along a straight line direction. An excimer laser beam source is deployed to project through the photomask on a substrate coated with a polymeric material while the substrate is moving in a direction normal to the straight line direction for the polymeric material to receive laser beam projection with different time period. The polymeric material thus may be etched to different depth to form a three dimensional pattern desired. By projecting and etching the polymeric material two times at different directions or through different photomask patterns, a sphere like or non-sphere like surface of micro array structure may be obtained.
