  • Patent number: 9059694
    Abstract: An object is to provide a low-power semiconductor device which does not require a latch circuit to hold data at the output of inverter circuits. In the semiconductor device, an input of a first inverter circuit is connected to an input terminal through a source and a drain of a first transistor. An input of a second inverter circuit is connected to an output of the first inverter circuit through a source and a drain of a second transistor. An output of the second inverter is connected to an output terminal. An inverted clock signal and a clock signal are input to gates of the first transistor and the second transistor, respectively. The first and the second transistor have extremely low off-current, which allows the output potential of the device to remain unchanged even when the input varies.

  • Patent number: 8879027
    Abstract: On a liquid crystal panel, plural areas whose number is larger than that of temperature sensors are defined. In a memory, temperature relation information representing a relation between an output value of a temperature sensor and a temperature of each of the plural areas is stored. A controller acquires the output value of the temperature sensor and estimates, based on the temperature relation information and the acquired output value, the temperature of each of the plural areas. According to this configuration, the temperature of each of the plural areas defined on the liquid crystal panel can be obtained with a small number of temperature sensors.

  • Publication number: 20140320107
    Abstract: Provided is a DC-DC converter with improved power conversion efficiency. A transistor which is incorporated in the DC-DC converter and functions as a switching element for controlling output power includes, in its channel formation region, a semiconductor material having a wide band gap and significantly small off current compared with silicon. The transistor further comprises a back gate electrode, in addition to a general gate electrode, and a back gate control circuit for controlling a potential applied to the back gate electrode in accordance with the output power from the DC-DC converter. The control of the potential applied to the back gate electrode by the back gate control circuit enables the threshold voltage to decrease the on-state resistance when the output power is high and to increase the off-state current when the output power is low.

    Abstract: Provided is a technology which enables further improvement of the accuracy of the determination in the pattern matching processing. A dictionary learning device 1 includes a score calculation unit (score calculation means) 2 and a learning unit (learning means) 3. The score calculation unit 2 calculates a matching score representing a similarity-degree between a sample pattern, which is a sample of a pattern which is likely to be subjected to a pattern matching processing, and a degradation pattern resulting from a degrading processing on the sample pattern. The learning unit 3 learns a quality dictionary based on the calculated matching score and the degradation pattern. The quality dictionary is a dictionary which is used in a processing to evaluate a degradation degree (quality) of a matching target pattern of being pattern of an object on which the pattern matching processing is carried out.

  • Publication number: 20140263268
    Abstract: Embodiments of the invention generally relate to susceptor support shafts and process chambers containing the same. A susceptor support shaft supports a susceptor thereon, which in turn, supports a substrate during processing. The susceptor support shaft reduces variations in temperature measurement of the susceptor and/or substrate by providing a consistent path for a pyrometer focal beam directed towards the susceptor and/or substrate, even when the susceptor support shaft is rotated. The susceptor support shafts also have a relatively low thermal mass which increases the ramp up and ramp down rates of a process chamber. In some embodiments, a custom made refractive element can be removably placed on the top of the solid disc to redistribute secondary heat distributions across the susceptor and/or substrate for optimum thickness uniformity of epitaxy process.
