Abstract: Since the PN junction of a photodiode is formed of a silicon substrate having a low impurity concentration and an epitaxial layer, the width of the depletion layer in the PN junction is formed wider, the parasitic capacitance by the junction capacitance is lowered, and the diffusion length of the silicon substrate is formed longer. Besides, a buried layer containing a high impurity concentration is formed by a high energy ion implantation method in such a depth that the buried layer cannot be depleted by a reverse voltage applied to the PN junction, which is served as a region to lead out the anode, which accordingly results in a low parasitic resistance at the anode. Thereby, the invention provides a semiconductor device including a photodetector and a method of manufacturing the same that achieves a high photoelectric conversion sensitivity and an excellent frequency characteristic at the same time.

Abstract: A three-dimensional (3D) surface profile measurement method and apparatus uses projected energy with a known spatially varying wavelength distribution over the surface of objects in a scene. The varying wavelength of the light corresponds to the angle at which the light is emitted from a light source. Given this correspondence, light reflected from the scene can be identified by wavelength as to angle at which it was emitted. Triangulation can then be used to determine the distance to the point in the scene from which the detected light is reflected. When performed over a number of points on the scene, a three-dimensional profile of the scene can be generated.

Abstract: A novel device combines the functions of a pager unit and a personal electronic device such as a radio tuner, a cassette tape player, or a compact disc player. Upon receipt of a transmission, the pager unit interrupts the audio signal of the personal electronic device with an alert signal which is heard through the headphones of the personal electronic device. The user can then view the received transmission. Alternatively, if the transmission is an audio or voice mail transmission, the transmission may be heard through the headphones following the alert signal.
