The MOS capacitor consists of a Metal-Oxide-Semiconductor structure which has the semiconductor substrate with a thin oxide layer and a top metal contact, referred to as the gate. A second metal layer forms an Ohmic contact to the back of the semiconductor and is called the bulk contact.

Notes on the Solution of the Poisson-Boltzmann Equation for MOS Capacitors and MOSFETs, 2nd Edition
out of 5 stars
24 Oct 2012 | | Contributor(s):: Mark Lundstrom, Xingshu Sun
These notes are intended to complement the discussion on pp. 63 – 68 in Fundamentals of Modern VLSI Devices by Yuan Taur and Tak H. Ning . (Another good reference is Semiconductor Device Fundamentals by R.F. Pierret .) The objective is to understand how to treat MOS electrostatics without...
MOS-C VFB Calculation: Comparison of Theoretical and Simulation Values
05 Feb 2012 | | Contributor(s):: Stella Quinones
The flatband voltage is calulated based on device physics theory and is compared to the value determined from the simulation of a MOS-Capacitor using the MOSCap simulation tool on the nanoHUB.org website. By completing this exercise, the student is able to compare the mathematical model of the...

SCHRED Exercise: MOS Capacitor Analysis
20 Jul 2010 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of this exercise is to examine the influence of semiclassical and quantum-mechanical charge description on the low-frequency CV-curves. It also teaches one the influence of poly-gate depletion on the low-frequency CV-curves.
Quantum Bound States Exercise
16 Jun 2010 | | Contributor(s):: Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
Exercise BackgroundQuantum-mechanical systems (structures, devices) can be separated into open systems and closed systems. Open systems are characterized with propagating or current carrying states. Closed (or bound) systems are described with localized wave-functions. One such system is a...
CV profile with different oxide thickness
20 Apr 2010 | | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck
C-V (or capacitance-voltage) profiling refers to a technique used for the characterization of semiconductor materials and devices. C-V testing is often used during the characterization process to determine semiconductor parameters, particularly in MOSCAP and MOSFET structures.C-V measurements...
