PHOSPHOR LAYER-COVERED OPTICAL SEMICONDUCTOR ELEMENT, PRODUCING METHOD THEREOF, OPTICAL SEMICONDUCTOR DEVICE, AND PRODUCING METHOD THEREOF

摘要

A method for manufacturing a phosphor layer-covered optical semiconductor element includes the steps of: opposing a phosphor layer including a phosphor to an optical semiconductor element; and controlling the color tone of light emitted from the optical semiconductor element through the phosphor layer by controlling the thickness of the phosphor layer.
