Patent ID: 11862756
Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A method of manufacturing light emitting diode (LED) dies, comprising:
forming a transduction structure having a back side, a front side opposite the back side, a first semiconductor material having a first surface at the back side, a second semiconductor material having a second surface at the front side, and a light-emitting active material between the first and second semiconductor materials;
forming an electrical connector electrically coupled to the second semiconductor material by—
electrically coupling a base material of the electrical connector to the second semiconductor material, the base material having a top side facing the front side of the transduction structure,
constructing a buried contact having the base material extending through the first semiconductor material and the active material from the back side of the transduction structure to a depth in the second semiconductor material such that the base material separates a first portion of the active material from a second portion of the active material, and
depositing a reflective material over a portion of the base material nearest the front side of the transduction structure and between the base material and the second semiconductor material, wherein the reflective material covers the top side of the base material and has a higher reflectivity than the base material; and

disposing an insulation material electrically separating the electrical connector and at least one of the first semiconductor material and the active material.
