Abstract
Disclosed herein are techniques for bonding components of LEDs. According to certain embodiments, a device includes a first component having a semiconductor layer stack including an n-side semiconductor layer, an active light emitting layer, and a p-side semiconductor layer. A plurality of mesa shapes are formed within the n-side semiconductor layer, the active light emitting layer, and the p-side semiconductor layer. The semiconductor layer stack comprises a III-V semiconductor material. The device also includes a second component having a passive or an active matrix integrated circuit within a Si layer. A first dielectric material of the first component is bonded to a second dielectric material of the second component, first contacts of the first component are aligned with and bonded to second contacts of the second component, and a run-out between the first contacts and the second contacts is less than 200 nm.
