In this paper, a high-performance and low-HCI (Hot carrier injection) degradation LDMOS (Lateral double diffused metal oxide semiconductor) device is introduced. It consists of an additional mini LOCOS (Local oxidation silicon) field plate combined with STI (Shallow trench isolation) without complex fabrication process. A series devices have been fabricated, the corner profile optimized. The proposed hybrid FP(Field plate) can effectively reduce electric peak, BV (Breakdown voltage) achieves...
In this work, the effects of mini-local oxidation silicon (LOCOS) field plate’s bottom physical profile on devices’ breakdown performance are analyzed through technology computer-aided design simulations. It is indicated that “abrupt” could certainly do with an optimization. This paper introduces effective process improvement method by etching bias power adjustment and time reduction. The upgradation plate has been proved transmission electron microscope cross-section analysis. angle for...
The design of LDMOS (Lateral double diffused metal oxide semiconductor) devices with CFP (Contact field plate) has been great significance in recent years, according to its advantages low resistance and high switch efficiency. In this paper, ultra-low Ron,sp (Specific on-resistance) device is simulated, designed, fabricated. effects on FOM (Figures-of-merits) characters from physical dimensions, including plate length L, thickness H, slot contact width W, have analyzed discussed. best...
Natural ester has been successfully put into commercial use in high voltage transformer recent years for its advantages fire resistance, biodegradation, etc. This paper presents experimental results of dissolved gas analysis(DGA) natural under AC breakdown faults with and without oil-pressboard interface, mineral oil were tested as comparison. The revealed that more CO generated than after breakdown, the proportion fault gases changed when interface involved. It was also found significant...
Dodecylbenzene (DDB) insulating oil is widely used in high-voltage submarine oil-filled cables, but there a lack of research on the gas production law DDB under fault which can be for diagnosis equipment filled with oil. Herein, we built thermal simulation system to study seven gases (H2, CH4, C2H6, C2H4, C2H2, CO, CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) produced by paper and without at 100°C~350°C. Existing dissolved...
Dodecylbenzene insulating oil is a liquid dielectric material widely used in self-contained high-voltage cables and accessories with low viscosity, loss, good gas evolution electric field high breakdown strength, but has less research application China. In this paper, dodecylbenzene produced by an enterprise Nanjing taken as the object, its physical, chemical electrical properties were tested. The production law of 7 characteristic gases (H2, CO, CO <sub...
