Sample EE6303 Linear Integrated Circuits and Applications Important questions:
1. What are the advantages of polysilicon gate MOSFET over aluminum gate?
The silicon film is of high quality and suitable for IC manufacturing. SOI provides a speed advantage because the source/drain to body junction capacitance is practically eliminated because the junctions extend vertically to the buried oxide. The cost of a SOI wafer is many times higher than an ordinary silicon wafer and can increase the total Fabrication cost of IC chips by ~30%.
2. What are the two common methods for obtaining integrated capacitors?
Monolithic junction capacitor
Thin-flim capacitor (ee6303 linear integrated circuits and applications important questions)
3. What is the purpose of oxidation process in IC fabrication?(Apr 2010)
The silicon wafers are stacked up in a quartz boat & then inserted into quartz furnace tube. The Si wafers are raised to a high temperature in the range of 950 to 1150oC & at the same time, exposed to a gas containing O2 or H2O or both.
The chemical action is Si + 2H2O ——> Si O2+ 2H2
4. What is parasitic capacitance? (Apr 2010)
In electrical circuits, parasitic capacitance is an unavoidable and usually unwanted capacitance that exists between the parts of an electronic component or circuit simply because of their proximity to each other.
5. What is meant by ion implantation?(Nov 2011, Nov 2012)
The conductivity of the semiconductor increases when small impurity is added to it. The process of adding impurity is called doping while the impurity to de added is called dopant.so ion implantation is a process of adding dopant to the silicon substrate. The ion implantation process is controllable, reproducible and also there are no unwanted side effects. (ee6303 linear integrated circuits and applications important questions)
