Passage

Read the passage and answer the following five questions:

The metal oxide semiconductor field effect transistor is the most important device for very large scale integrated circuits such as microprocessor and semiconductor memories. MOSFET is also becoming a power device. The principle of field effect transistor was first proposed by Dillen Field in 1930. The current in a MOSFET is transported by carriers of one polarity and is usually referred as unipolar device. The MOSFET is a member of the family of field effect transistors. It is fabricated with various semiconductors such as Si, GaAs and SiC with various insulators. The most important system is Si – SiO2 interface.
