  • Publication number: 20170005125
    Abstract: To obtain an imaging unit, a lens barrel, and a portable terminal which can effectively suppress spring-back of solid-state imaging elements, while facilitating height lowering thereof. An imaging unit includes: a solid-state imaging element; and an imaging lens for forming a subject image on a photoelectric conversion part of the solid-state imaging element. An imaging surface of the solid-state imaging element is curved in a manner that a peripheral side is inclined toward an object side relative to a screen center. The imaging lens constrains the solid-state imaging element to prevent a radius of curvature of the imaging surface from varying. Thus, field curvature, distortion aberration, and comatic aberration are appropriately corrected.

  • Patent number: 9453683
    Abstract: A controller of a heat treatment apparatus forms a phosphorous-doped polysilicon film (D-poly film) on a semiconductor wafer, and determines whether the D-poly film satisfies a target heat treatment characteristic. When it is determined that the target heat treatment characteristic is not satisfied, the controller calculates a temperature in a reaction tube and flow rates of process gas supply pipes, which satisfy the target heat treatment characteristic, based on a heat treatment characteristic of the D-poly film and a model indicating relationships between changes in the temperature in the reaction tube and the flow rates of the process gas supply pipes, and a change in a heat treatment characteristic. The controller forms the D-poly film on the semiconductor wafer according to heat treatment conditions including the calculated temperature and the calculated flow rates, so as to satisfy the target heat treatment characteristic.
