Latest Patents

Danti Chen's latest patents include a method for a GaN vertical microcavity surface-emitting laser (VCSEL). This patent describes methods and structures for forming vertical-cavity light-emitting devices. An n-side or bottom-side layer may be laterally etched to create a porous semiconductor region, which is then converted to a porous oxide. The porous oxide serves as a current-blocking and guiding layer, directing bias current through the active area of the light-emitting device. Additionally, distributed Bragg reflectors can be fabricated on both sides of the active region to form a vertical-cavity surface-emitting laser. The light-emitting devices may be constructed from III-nitride materials.

Another notable patent involves large-area, laterally-grown epitaxial semiconductor layers. This patent outlines structures and methods for confined lateral-guided growth of a large-area semiconductor layer on an insulating layer. The semiconductor layer is formed through heteroepitaxial growth from a selective growth area within a vertically-confined, lateral-growth guiding structure. These guiding structures can be arranged in arrays over a substrate region, allowing for the coverage of a majority of the substrate with laterally-grown epitaxial semiconductor tiles. Quality regions of low-defect, stress-free GaN can be grown on silicon.
