  • Guides lithographically fabricated on semiconductor devices
    Patent number: 6798953
    Abstract: A structure that includes a substrate, typically a semiconductor chip such as a VCSEL or photodetector chip, and a guide for aligning a signal conveying device, typically an optical fiber, to a transducer such as an optoelectronic device on the semiconductor chip. The guide is formed, in a preferred embodiment, by lithographically exposing and developing a thick layer of photoresist. The structure is assembled by placing and securing the signal conveying device into a cavity-like region of the guide.
