High Temperature Specific Components
... Leakage current in a semiconductor junction is heavily dependent on temperature. This means that isolation will be lost at high temperature in a junction isolated process while an SOI-process is still operational. Elevated temperature also accelerates ageing effects in an integrated circuit. One exa ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
