ABSTRACT:
A system and method of improving the thermal characteristics of a system having at least two electronic devices (100, 102; 300, 302) connected to a common substrate (104; 304). Thermal characteristics include the amount of heat transferred from one device to another and spatial uniformity of heat transferred from one device to another. Thermal conductive paths between two electronic devices are lengthened by forming an opening (200; 306) through the substrate between the two devices. Heat conduction between the devices is reduced due to increased radiation and convection in the longer thermal conductive paths. The uniformity of heat distribution between the devices is improved due to a narrower range of conducting path lengths. In a specific embodiment, heat conduction is reduced between amplifiers and photosensors used in spectrometers. In the specific embodiment, a temperature sensor (308) is used to further reduce thermal effects.
