Two-Dimensional Steady and Transient Conduction - Cooling a very
large scale microelectronic chip,
A simplified
representation for cooling in very large-scale integration (VLSI)
of microelectronics is shown in the sketch below. A silicon chip is
mounted in a dielectric substrate, and one surface of the system is
convectively cooled, while the reminding surfaces are well
insulated from the surrounding. The problem is rendered two
dimensional by assuming the system to be very large in the
direction perpendicular to the paper....
