  • Publication number: 20150229329
    Abstract: An object is to enable erasure correction even at the time of a degeneration operation and reduce the number of necessary parallel media through dynamic setting of degree of redundancy. A parallel data encoding/decoding system performs parallel data transmissions using a plurality of lanes from an encoder to a decoder. The encoder encodes products of elements of an encoding vector M of symbols of each lane and a state vector U indicating validity of the symbols, and transmits the state vector U along with a transmission vector Y obtained through the encoding. The decoder decodes a subset Msub constituted of valid elements of the encoding vector M using a received reception vector Y?, the received state vector U, and an erasure vector E indicating whether each element of the transmission vector has been erased in a transmission/reception section.

  • Patent number: 8133663
    Abstract: A pattern forming method includes forming a resist film or sequentially forming a resist film and a protection film in this order on a surface of a substrate; then, performing immersion light exposure that includes immersing the resist film or the resist film and the protection film formed on the substrate in a liquid during light exposure, thereby forming a predetermined light exposure pattern on the resist film; and performing a development process of the light exposure pattern by use of a development liquid, thereby forming a predetermined resist pattern. After the immersion light exposure and before the development process, the method further includes performing a hydrophilic process of turning a surface of the resist film or the protection film serving as a substrate surface into a hydrophilic state to allow the substrate surface to be wetted with the development liquid overall.

  • Patent number: 8007968
    Abstract: In the present invention, patterning for the first time is performed on a film to be worked above the front surface of a substrate, and the actual dimension of the pattern formed by the patterning for the first time is measured. Based on the dimension measurement result of the patterning or the first time, the condition of patterning for the second time is then set. In this event, the condition of the patterning for the second time is set so that a difference between the dimension of the patterning for the first time and its target dimension is equal to a difference between the dimension of the patterning for the second time and its target dimension. Thereafter, the patterning for the second time is performed under the set patterning condition.
