Abstract

Previous studies have already shown that the use of alternative gate shapes for planar and tridimensional MOSFETs are capable of boosting their analog and digital electrical performances and their ionizing radiations robustness. In this scenario, this work has the objective to study the impact of the use of octagonal layout style (OCTO), as the basic cell, to the implementing of the Planar Power MOSFET (PPM). The main results of this paper show that the PPM layouted with OCTO layout styles, as the basic cells, are able to improve the drain saturation current (I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DS_sat</inf> ) about 668%%, in relation to that implemented with conventional rectangular layout style, considering that they present the same gate area and bias conditions. Therefore, this type of layout approach can be considered an alternative layout to improve the electrical performance of PPMs.
