LDMOS Thermal SOA Investigation of a Novel 800V Multiple RESURF with Linear P-top Rings

Abstract

In this paper, Technology Computer-Aided Design (TCAD) is used to investigate the thermal characteristic and Thermal Safe Operating Area (T-SOA) of a novel 800V Multiple RESURF LDMOS with linear P-top Rings. Two methods of critical temperature extraction are presented and the agreement between these two methods is proven. The effects of Initial Front Rise time (IFR) and other parameters on the thermal characteristic of the device are inspected. Finally, the simulation result has an agreement with the analytic solution. Therefore, the analytic solution can replace the 3D simulation for large device which is not able to be performed using current available TCAD tools.

Disclosure of Fraud Through Forensic Accounting, Audit Investigation and Auditor Professionalism

“…An investigative audit is one of the activities in the context of implementing a fraud disclosure strategy with an investigative approach. An investigative audit, as defined by Herlambang (2011) in Nasha Ilhulhaq et al ( 2019), is a type of audit or examination that aims to identify and reveal fraud or crime by employing approaches, procedures, or techniques commonly used in an investigation or investigation of a crime. According to agency theory, fraudulent behavior is motivated by the actions of managers who are dissatisfied with the incentives they receive and attempt to obtain them through unethical means.Isam Ahmad Fauzan (2015) concluded that the investigative audit has a positive effect on fraud disclosure.…”
