  • Publication number: 20220276405
    Abstract: An optical sensor includes a light source, a light receiver, and a convex portion. The light source emits light to an object. The light receiver receives reflected light of the emitted light reflected by an object and generates a signal showing a light reception result. The convex portion has a height higher than a height of the light source and the light receiver. The convex portion is between the light source and the light receiver to block reflected light from the light receiver when light from the light source is reflected within a range of a predetermined distance from the convex portion. The light receiver outputs a signal to show a light reception result of equal to or less than a threshold amount of light indicating that the reflected light is not received in response to proximity of the object being within a range of a predetermined distance.

  • Patent number: 11354476
    Abstract: There is a significant precaution when performing random dopant fluctuation by using the drift-diffusion model that is the basis of the conventional device simulation. Because the continuation by a long wavelength approximation was done to derive said drift-diffusion model. That is how to recover the location dependence of discrete impurity ions in the long wavelength approximation. For example, in the case that there is an impurity ion near to the interface to an insulating film, the charge density of an impurity ion, which was made continuous in the conventional method, is unable to catch the charge density change due to polarization at the interface. Because this polarization is dependent of the location of a discrete impurity ion near to the interface.
