SEMICONDUCTOR WAFER, SEMICONDUCTOR LIGHT-EMITTING DEVICE, OPTICAL TRANSMISSION DEVICE, INFORMATION PROCESSING DEVICE, AND METHOD FOR MANUFACTURING SEMICONDUCTOR LIGHT-EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor wafer capable of improving a manufacturing yield of a surface-emitting semiconductor laser.SOLUTION: A plurality of element formation regions 10 are formed in a wafer 100 in which a plurality of surface-emitting semiconductor laser elements are formed. A VCSEL20 and an electrode pad 50 for driving this VCSEL20 are formed in the element formation regions 10. An annular hydrophobization region 30 in which a surface of an interlayer insulating film is hydrophobized is formed around the VSCEL20, and an annular groove 40 is formed outside the VCSEL20. A resin 70 is potted in the element formation regions 10 so as to cover the VCSEL20.
