This manuscript presents a heat transfer model for predicting the three-dimensional temperature field in a multi-die 3D IC with unequally-sized die. This problem is solved iteratively using solutions of three simpler heat transfer problems outlined in the manuscript.

It will come as no surprise that we can also do triple integrals—integrals over a three-dimensional region. The simplest application allows us to compute volumes in an alternate way. To approximate a volume in three dimensions, we can divide the three-dimensional region into small rectangular boxes, each $\Delta x\times\Delta y\times\Delta z .

A metal bar with length L= ˇis initially heated to a temperature of u 0(x). The temper-ature distribution in the bar is u(x;t).
