摘要:
Disclosed is a semiconductor device which comprises one or more metal-insulator-semiconductor field effect transistors (MISFETs), each including: a gate insulating film composed of a silicon oxide film, a first hafnium-containing nitrided silicate film, and a second hafnium-containing nitrided silicate film which are sequentially deposited on a substrate; and a gate structure having an electrode consisting of a metal silicide deposited on the gate insulating film. The first hafnium-containing nitrided silicate film has a hafnium concentration in a range from 5 to 10% and has a nitrogen concentration in a range from 5 to 10%. The second hafnium-containing nitrided silicate film has a hafnium concentration in a range from 50 to 60% and has a nitrogen concentration in a range from 20 to 45%. The gate insulating film has a thickness in a range from 1.8 to 3.0 nm.

A radiation image capturing apparatus includes: a radiation detector for detecting charge information; an analog multiplexer for passing an analog charge information signal read out from each pixel of the radiation detector, alternately in a first order and a second order opposite to the first order; an analog signal amplifier for amplifying the analog charge information signal; an analog/digital converter for converting the analog charge information signal to a corresponding digital charge information signal; and a signal correcting unit for using one of a first digital charge information signal corresponding to the analog charge information signal that has passed through the analog multiplexer in the first order and a second digital charge information signal corresponding to the analog charge information signal that has passed through the analog multiplexer in the second order, to correct the other of the first digital charge information signal and the second digital charge information signal.

A dimming signal generation device outputs a square wave voltage signal having an on-duty corresponding to a dimming level to a dimming signal line from a time point when a predetermined time period has elapsed after power-up. In the dimming signal generation device, a specific voltage is outputted to the dimming signal line for the predetermined time period after the power-up.

A lighting device for a solid-state light source includes a DC power source circuit section which flows a current in a solid-state light source by using a charging/discharging current or either one of charging and discharging currents of a inductor connected in series to a switching element, and a current control section having a first switching control unit for changing an ON width of the switching element depending on a dimming level and a second switching control unit for controlling an ON timing of the switching element. The second switching control unit changes a time until the switching element is turned on from a zero-crossing of the discharging current of the inductor such that the time becomes substantially the same when the dimming level is equal to or greater than a predetermined level, and the time becomes longer when the dimming level is less than the predetermined level.
