  • Patent number: 9759656
    Abstract: The inspection apparatus includes: a stage that retains the inspection sample; a light irradiator that irradiates the inspection sample with light having a predetermined wavelength to cause the inspection sample to emit a terahertz wave; a detector that detects electric field intensity of the terahertz wave emitted from the inspection sample; and a comparator that compares the electric field intensity of the terahertz wave emitted from the inspection sample to an evaluation reference value. The evaluation reference value is a value (for example, 90% of a saturation value) smaller than an absolute value of the saturation value of the electric field intensity of the terahertz wave, the terahertz wave being generated by irradiating a reference sample, which is a reference of the inspection sample, with the light while different voltages are applied to the reference sample.

  • Patent number: 9698148
    Abstract: A field effect transistor (FET) having one or more fins provides an extended current path as compared to conventional finFETs. A source terminal is disposed on a first fin between a first dummy gate and a gate structure. A drain terminal is disposed on a second fin between a second dummy gate and a third dummy gate. A first gate oxide layer disposed under second and third dummy gates is made to be thinner than a second gate oxide layer disposed under the first dummy gate and the gate structure. By making the first gate oxide layer thinner, an overall footprint of the finFET device is reduced.
