    摘要: A field effect transistor includes a semiconductor substrate having a first conduction type and functioning as a drain of the field effect transistor, and a back gate region formed in the semiconductor substrate and having a second conduction type opposite to the first conduction type. The field effect transistor also includes a source region formed in the back gate region and having the first conduction type, an insulator film formed on the semiconductor substrate and having first and second windows, and a gate electrode covered by the insulator film and located so that a channel is formed in the back gate region. Further, the field effect transistor includes a guard region formed in the semiconductor substrate and located close to the back gate region. The guard region has the second conduction type, and has a first portion located on a first side of the guard region facing the back gate region and a second portion located on a second side opposite to the first side. A first breakdown voltage obtained at a first junction between the second portion and the semiconductor substrate is lower than that obtained at a second junction between the back gate region and the semiconductor substrate. Furthermore, the field effect transistor includes an electrode formed on the insulator film and connecting the guard region and the back gate region via the first and second windows.

    摘要: A distance measuring apparatus measuring a distance to an object is disclosed. The apparatus includes a light projector projecting an irradiating light onto the object; a first receiver receiving and converting a reflected light into a received light signal; a second receiver adjacent to the light projecting unit, the second receiver receiving and converting the irradiating light into a reference signal, the second receiver being different from the first receiver; and a distance measuring unit measuring the distance based on a time. The distance measuring unit calculates an integrated waveform based on a reference waveform of the reference signal and a waveform of the received light signal, determines, based on the integrated waveform, a time from projection of the irradiating light onto the object by the light projecting unit until reception of the reflected light by the first receiver, and calculates the distance based on the determined time.
