Abstract
Three mathematical models for the thermal damage of semiconductor structures with a single junction (diodes, FETs, single-heterojunction bipolar transistors, and photodiodes) are characterized. Similarly to the Wunsch-Bell model, the proposed models are based on solutions to the 1D heat equation. In contrast to the Wunsch-Bell model, in which the thickness of the junction is assumed infinite and a rectangular acting pulse has an infinitely short leading edge, the proposed models take into account the finite dimensions of the junction; the pulse shape; and the pulse-leading-edge steepness, which is important for any mechanism of the functional damage. Conditions for the applicability of each model for the estimation of the criterial levels of functional damage in semiconductor structures are determined. It is emphasized that the heat equation should be solved with allowance for matched initial and boundary conditions.
