Abstract:
A method, and associated apparatus, for attaching a component (e.g., an electronic and/or optoelectronic component) is provided which can facilitate low-voiding of an attachment layer. The method includes disposing an attachment material layer over a surface, providing the component having a backside surface, disposing a portion of the backside surface of the component over a first portion of the attachment material layer such that a substantial portion of the backside surface of the component is not disposed over the attachment material layer, and moving the component such that the component is attached to at least a portion of the attachment material layer that is substantially larger than the first portion of the attachment material layer. The attachment material can include a solder. A light-emitting device is also described that comprises a component including a light-emitting die, wherein the component is supported by a substrate, and wherein the light-emitting die comprises a light emission surface and a backside surface disposed opposite the light emission surface. The light emission surface of the light-emitting die has an area greater than or equal to 1 mm2 and an attachment material layer is disposed between the backside surface of the light-emitting die and the substrate, wherein the attachment material layer has voiding of less than 5% of an area of the backside surface.
