Abstract: We present TCAD-based methodologies that go beyond process and device simulations of single transistors. We show that TCAD solvers can be used as effective tools to resolve the intricacies of current and future technology nodes that are otherwise difficult to access using EDA-level methods alone.

Electrical characterization of advanced MOSFETs towards analog and RF applications

IEEE LAEDC, San Jose, Costa Rica, 2020, 

doi: 10.1109/LAEDC49063.2020.9073536

Abstract - This invited paper reviews main approaches in the electrical characterization of advanced MOSFETs towards their target analog and RF applications. Advantages and necessity of those techniques will be demonstrated on different study cases of various advanced MOSFETs, such as FDSOI, FinFET, NW in a wide temperature range, based on our original research over the last years.

This is not exactly compact modelling, but it's a nice thing to see:

SPICE-aided modelling of dc characteristics of power bipolar transistors with self-heating taken into account

Abstract
This paper deals with the problem of calculations of the dc characteristics of power bipolar transistors (BJTs) with self-heating taken into account. The electrothermal model of the considered devices dedicated for PSPICE is presented. The correctness of the model was verified experimentally in all ranges of the BJT operation. Two transistors - BD285 and 2N3055 - were arbitrarily selected for investigation. A good agreement between the measured and calculated characteristics of these transistors was observed.
