  • Publication number: 20110225149
    Abstract: An input assistance device includes: an operation unit configured to accept information selected by a user from a plurality of input candidates; a storage unit configured to store a priority for displaying the plurality of input candidates according to a display order, the priority determined based on an input history of information accepted by the operation unit in association with each of the plurality of input candidates; and a control unit configured to refer to the storage unit, to change the display order of the input candidates determined based on the priority into other display order by replacing a first input candidate among the plurality of input candidates in a first range from a top percentile priority with a second input candidate in a second range that is outside of the first range, and to output the plurality of input candidates according to the other display order.

  • Patent number: 8017528
    Abstract: A thermal cycle includes: increasing a temperature from an initial temperature to a temperature T1 at an arbitrary rate R1 (° C./sec); holding the temperature at the temperature T1 for an arbitrary period t1 (sec); increasing the temperature from the temperature T1 to a temperature T2 at a rate R2 (° C./sec) of 1.0×107 (° C./sec) or less; and holding the temperature at the temperature T2 for a period t2 (sec) of 50 msec or less. The thermal cycle thereafter includes: decreasing the temperature from the temperature T2 to the temperature T1 at a rate R1? (° C./sec) of 1.0×107 (° C./sec) or less; holding the temperature T1 for an arbitrary period t3 (sec); and decreasing the temperature from the temperature T1 to a final temperature at an arbitrary rate R2? (° C./sec). Such a thermal cycle is successively repeated in a plurality of iterations.

  • Patent number: 7981816
    Abstract: An impurity-activating thermal process is performed after a target is subjected to an impurity introduction step. In this thermal process, while a spike RTA process including a holding period for holding a temperature at a predetermined temperature is performed, at least one iteration of millisecond annealing at a temperature higher than the predetermined temperature is performed during the holding period of the spike RTA process.
