P-channel Metal Oxide Semiconductor: pertains to MOS devices constructed on an N-type silicon substrate in which holes flow between source and drain contacts.
Positive channel Metal Oxide Semiconductor. (see NMOS).
a MOS device that uses holes as the carrier, holes carry a positive charge hence PMOS.
P-channel MOS transistor where the active carriers are holes flowing between p-type source and drain regions in an electrostatically formed p-channel in an n-type silicon substrate. The channel, the source, and the drain are made of a p-type semiconductor material. (HWDI series)
P-channel MOSFET, where the primary current carriers are positively charged "holes"
