Provided is a laser annealing apparatus 1 for heat-treating a surface of a substrate 30 comprising: a pulse oscillation laser source 10 which generates a pulse laser with gentle rise time and long pulse width; a continuous wave laser source 20 which generates a near-infrared laser for assisting annealing; optical systems 12, 22 which shape and guide beams 15, 25 of the two types of lasers respectively so as to irradiate the surface of the substrate 30 therewith; and a moving device 3 which moves the substrate 30 relatively to the laser beams 15, 25 to allow scanning of the combined irradiation of the two types of laser beams. According to this apparatus, deep activation of impurities can be performed in a thick semiconductor substrate with large heat capacity while securing sufficient light penetration depth and thermal diffusion length therefor..


Modular push switch mechanism

The present invention is directed to switch device that includes a switch actuator having a user-accessible surface, the user accessible surface including an indicator element and an interior channel optically coupled to the indicator element. The switch actuator is configured to actuate a mechanical linkage by moving between a first actuator position and a second actuator position in response to a user-stimulus, the mechanical linkage actuation driving the set of electrical contacts between a first contact state and a second contact state.

Optical information recording medium and recording/reproducing device

An optical information recording medium has: a recording layer; a super-resolution functional layer; and a protective layer. Letting n be the refractive index of the protective layer with respect to a laser beam focused by a focusing optical system, λ, be the wavelength of the laser beam, and ds be the depth of recording marks, when the super-resolution functional layer is irradiated by the focused laser beam, it forms a focused light spot including central light that irradiates the recording marks and peripheral light that irradiates a region outside the central light.
