  • Publication number: 20070196589
    Abstract: A material composition, which is used as a liquid resist, includes a first component comprising a monomer portion and at least one cationically polymerizable functional group, and a crosslinker reactive with the first component and comprising at least three cationically polymerizable functional groups. The material composition also includes a cationic photoinitiator. Upon exposure to UV light, the material composition crosslinks via cure to form a cured resist film that is the reaction product of the first component, the crosslinker, and the cationic photoinitiator. An article includes a substrate layer and a resist layer formed on the substrate layer from the material composition.

  • Patent number: 7142626
    Abstract: An apparatus and method is disclosed for automatically controlling multi-input-single-output (MISO) systems or processes. The control output signal of a single-input-single-output (SISO) automatic controller is converted by a reverse, sequential or combined split-range setter into a plurality of ranges of signals so that the SISO controller is converted to a single-input-multi-output (SIMO) automatic controller based on certain criteria; and the resulting controller output signals are able to manipulate a plurality of actuators to control one continuous process variable in different operating conditions. Without the need of building process mathematical models, this inventive apparatus and method is useful for automatically controlling unevenly paired multivariable systems or processes where there are more system inputs than outputs including but not limited to pH processes, chemical reactors, and air handling units.

  • Publication number: 20060237881
    Abstract: A method of fabricating a device including imprinting a mold having a protrusion against a substrate having a resist layer such that the protrusion engages the resist layer. The mold further has a mask member positioned generally adjacent the resist layer. Radiation energy is then transmitted through the mold and into the resist layer; however, the mask member substantially prevents transmission of the radiation energy therethrough, thereby defining an unexposed area in the resist layer. Once the mold is removed from the substrate, which consequently forms a first feature from nanoimprinting, the unexposed area of resist layer is removed through dissolving in a developer solution.
