Description

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.

  1. Exercise for MOS Capacitors: CV curves and interface and Oxide Charges

    03 Aug 2009 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    This exercise is designed to teach the students how the CV curves of an ideal MOS Capacitor change in the presence of oxide or interface charges.

  2. Exercise: CV curves for MOS capacitors

    02 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    This exercise demonstrates to the students how the low-frequency CV curves in MOS capacitors change with changing the gate workfunction, the oxide thickness and the dielectric constant. It also demonstrates the doping variation of the high-frequency CV curves.NSFNSF
