[amp_mcq option1=”Silicon crystal” option2=”Silicon-on-sapphire” option3=”Phosphorus” option4=”Silicon-di-oxide” correct=”option1″]<\/p>\n
The correct answer is A. Silicon crystal.<\/p>\n
A bulk substrate is a piece of semiconductor material that is used as the foundation for a semiconductor device. The most common type of bulk substrate is silicon crystal, which is a single crystal of silicon. Silicon crystals are grown by the Czochralski process, which involves melting silicon and then slowly pulling a single crystal out of the melt.<\/p>\n
Silicon-on-sapphire (SOS) is a type of semiconductor material that is made by growing a thin layer of silicon on a sapphire substrate. SOS is used in some high-performance applications because it has better thermal conductivity than silicon crystal.<\/p>\n
Phosphorus is a chemical element that is used as a dopant in silicon to create n-type silicon. Doping is the process of adding impurities to a semiconductor material to change its electrical properties.<\/p>\n
Silicon dioxide (SiO2) is a type of semiconductor material that is used as an insulator in semiconductor devices. SiO2 is also used as a passivation layer on the surface of silicon wafers.<\/p>\n
In conclusion, the most common type of bulk substrate used in nMOS fabrication is silicon crystal.<\/p>\n","protected":false},"excerpt":{"rendered":"
