How can silicon carbide be synthesized?5 answersSilicon carbide can be synthesized using various methods such as solar heating, sol-gel method, sintering, pyrolysis, microwave synthesis, and chemical vapor deposition. Carbothermal reduction can also be used, where silicon dioxide and carbon sources are reacted at high temperatures. Another alternative method is the self-propagating high-temperature synthesis of binary silicon-carbon-based reactive multilayers. The synthesis process involves a solid-state reaction at relatively low annealing temperatures. The carbothermal reduction of methyl-modified silica aerogel/carbon mixtures has also been explored, resulting in the formation of β-silicon carbide powders. The phase evolution and morphology of the SiC powders depend on the C/SiO2 ratio. High-purity SiC powder can be obtained with specific C/SiO2 ratios and temperature conditions.

Which MOSFET has the maximum Vgs available in the market?5 answersThe MOSFET with the maximum Vgs available in the market is the newly developed MOSFET with thin gate oxide. This MOSFET has the ability to sustain high gate voltage while having a thin gate oxide. It consists of a MIM capacitor coupled floating gate poly and source/drain junction formed by low voltage well. The choice of capacitance coupling ratio, determined by the ratio of MIM capacitance and gate oxide capacitance, controls the device performances such as threshold voltage, I D -V D , and I D -V G characteristics. This MOSFET is particularly useful for the periphery circuits of single poly EEPROM operation in smart power management ICs that require a low density non-volatile memory.
