Title:
THREADED DEEP ULTRAVIOLET DEVICE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/087609
Kind Code:
A1
Abstract:
The present invention relates to the technical field of semiconductor devices. Disclosed is a threaded deep ultraviolet device structure, comprising an upper housing, a deep ultraviolet device, and a lower housing. The deep ultraviolet device is connected to the lower housing by means of the upper housing; a threaded structure is provided on the outer peripheral surface of the upper housing; the deep ultraviolet device comprises a substrate, a deep ultraviolet light-emitting diode, a protection diode, and a plurality of conductive metal posts; the plurality of conductive metal posts pass through the substrate; two ends of each conductive metal post are respectively connected to a first circuit layer structure and a second circuit layer structure; the deep ultraviolet light-emitting diode and the protection diode form a parallel circuit; the deep ultraviolet light-emitting diode and the protection diode are both disposed on the first circuit layer structure; a box dam is disposed outside the deep ultraviolet light-emitting diode and the protection diode; a lens is covered outside the deep ultraviolet light-emitting diode and the protection diode. The threaded deep ultraviolet device structure of the present invention realizes installation, replacement and repair without heating, thereby further improving the stability of a circuit board.
