PULSE OXIMETRY DEVICES AND SYSTEMS AND METHODS OF MAKING THE SAME

摘要

An array of emitters includes a device substrate having first and second sides, a thermally and electrically conductive layer disposed on the first side of the device substrate, and an interconnect layer disposed on a first plurality of portions of the second side of the device substrate. The array of the emitters further includes a plurality of emitters disposed in a second plurality of portions of the device substrate, where the plurality of emitters is electrically coupled to the thermally and electrically conductive layer. Also, the array of the emitters includes a plurality of wirebond contacts configured to electrically couple a portion of the interconnect layer to a corresponding emitter of the plurality of emitters, and a plurality of encapsulations, where one or more encapsulations of the plurality of encapsulations are disposed on at least a portion of a corresponding wirebond contact of the plurality of wirebond contacts.
