RESIN SHEET FOR ENCAPSULATING OPTICAL SEMICONDUCTOR ELEMENT AND OPTICAL SEMICONDUCTOR DEVICE

摘要

PURPOSE: A resin sheet for encapsulating optical semiconductor element and optical semiconductor device are provided to simplify the step for encapsulating the opto-semiconductor device and the step for mounting the metal layer on the substrate. CONSTITUTION: The resin sheet(1) for encapsulating the opto-semiconductor device includes the capsule resin layer(3), the adhesive resin layer(4), and the metal layer(5) and protection resin layer(2). The capsule resin layer is arranged adjacent to the metal layer. The protection resin layer is laminated on the capsule resin layer and metal layer to covers the capsule resin layer and metal layer. The capsule resin layer has the tapered shape expanded to the protection resin layer.
