In this paper we present a modular trench isolated high voltage SOI process with the possibility to integrate various types of high voltage transistors. The integration of these additional 650 V devices takes place in a modular approach which allows a high process flexibility to support different applications with a minimum number of additional or changed process steps.

Drastically device dimension shrinkage and rigorous requirement in automotive era puts Negative Bias Temperature Instability (NBTI) at the forefront of reliability issue recently. The PMOS parametric degradation during negative bias high temperature aging can depend on many process variables of the manufacturing flow. A study was carried out to explore the process related dependencies for high voltage PMOS transistor and to increase the device robustness against NBTI stress. In this papers, the process impact on the NBTI degradation were discussed. This investigation work provides methods for significant suppression of the NBTI degradation with silicon rich oxide (SRO) inter layer dielectric (ILD) liner and two-step gate oxidation.

A novel 0.18μm 200V integrated technology based on Partial SOI and lateral Super Junctions devices is presented. The dielectric isolation inherent in SOI allows simple and areaefficient integration of electrically floating CMOS and HV devices while removing all substrate carrier injection-related parasitic effects. The Super Junctions give a competitively low on-resistance of HVMOS and provide a wide-range breakdown voltage-scaling capability.

A combination of conventional cross sectional process and device simulations combined with top down and 3D device simulations have been used to design and optimise the integration of a 100V Lateral DMOS (LDMOS) device for high side bridge applications. This combined simulation approach can streamline the device design process and gain important information about end effects which are lost from 2D cross sectional simulations. Design solutions to negate detrimental end effects are proposed and optimised by top down and 3D simulations and subsequently proven on tested silicon.

The analog foundry business is not just a fad. Many logic foundries are seriously trying to move into this space. However, their transformation requires a change from being contract manufacturers that provide capacity and compete on the cost side to becoming a true provider of feature-rich process technologies with modular front and back ends and comprehensive process characterization. Also, they must offer a complete analog design ecosystem including libraries, analog IP and lots of design support – complicated by the absence of standards. Such capabilities would enable customers to reuse their analog IP across different applications and various technology platforms. This article explores barriers to such a transformation near-term.

Rapid increasing demand towards high voltage MOSFETs device integrated in low voltage CMOS analog and digital circuits for automobile and power management application has driven the development of 0.18um high voltage lateral diffused MOSFET (LDMOS) which capable to have 80V breakdown voltage. During designing this high voltage LDMOS, it is observed that the device performance is very dependent towards the device geometry particularly poly overlap length on STI. Thus, in this paper, the effects of poly overlap length on STI plate for high voltage LDNMOS have been studied extensively during the off-state condition.

Designing of high voltage LDMOS with a reduced surface field (RESURF) structure have been investigated to achieve the optimum figure of merit, maximum breakdown voltage accompanied with low on resistance. The drift region profile and device geometry plays important role to achieve target breakdown voltage of 80V. The electrical behaviors of the designed high voltage LDMOS for both on state and off state conditions are discussed analytically in this paper.
