Abstract: A device may include a wavelength converting layer on an epitaxial layer. The wavelength converting layer may include a first surface having a width that is equal to a width of the epitaxial layer, a second surface having a width that is less than the width of the first surface, and angled sidewalls.

Abstract: A first component with a first sidewall and a second component with a second sidewall may be mounted onto an expandable film such that an original distance X is the distance between the first sidewall and the second sidewall. The expandable film may be expanded such that an expanded distance Y is the distance between the first sidewall and the second sidewall and expanded distance Y is greater than original distance X. A first sidewall material may be applied within at least a part of a space between the first sidewall and the second sidewall. The expandable film may be expanded such that a contracted distance Z is the distance between the first sidewall and the second sidewall, and contracted distance Z is less than expanded distance Y.

Abstract: A device may include a substrate having a first embedded transistor in a first region and a second embedded transistor in a second region. The first region and the second region may be separated by trench extending through at least a portion of an epitaxial layer formed on the substrate. The first embedded transistor may be connected to a first light emitting diode (LED) and the second embedded transistor may be connected to a second LED. A first optical isolation layer may be between the epitaxial layer and the first region of the substrate. A second optical isolation layer may be between the epitaxial layer and the second region of the substrate.
