“…However, the literature results and our simulation show that for a PIN diode switching between a forward-biased state and a reverse-biased state, the use of a density-dependent lifetime covers both the low-and high-injection regions, and gives a more accurate current. [17] The width of the undepleted N − base is given by the following equation in the FVC method:…”

A finite volume charge method has been proposed to simulate PIN diodes and IGBT devices using SPICE simulators by extending the lumped-charge method. The new method assumes the local quasi-neutrality in the un-depleted N- base region and uses the total collector current, the nodal hole density and voltage as the basic quantities. In SPICE implementation, it makes the clear and accurate definitions of three kinds of nodes: the carrier density nodes, the voltage nodes, and the current generator nodes in the un-depleted N- base region. It uses the central finite difference to approximate electron and hole current generators, and sets up the current continuity equation in a control volume for every carrier density node in the un-depleted N- base region. It is easy to increase the number of nodes to describe the fast spatially varying carrier density in transient processes. We use this method to simulate IGBT devices in SPICE simulators and get a good agreement with TCAD simulations.

“…[11,12] It can use a density-dependent carrier lifetime, which is more accurate at a low injection level. [17] A further investigation of characteristics of the LC method is very useful. In the following we will analyze the main points and limitations of this method.…”
