Abstract: Electronic devices involving contact structures, and related components, systems and methods associated therewith are described. Contact structures (also referred to as electrical contact structures or electrodes) are features on a device that are electrically connected to a power source. The power source can provide current to the device via the contact structures. The contact structures can be designed to improve current distribution in electronic devices. For example, the contact resistance of the contacts may be modified to improve current distribution (e.g., by controlling the shape and/or structure and/or composition of the contacts). The contact structures may include an intervening layer (e.g., a non-ohmic layer) positioned between a surface of the device and a conductive portion extending from a conductive pad. The intervening layer and/or conductive portions may be designed to have certain shapes (e.g.

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.
