VMOS (pronounced /ˈviːmɒs/), is an acronym for Vertical Metal Oxide Semiconductor. Vmos is also used to describe the V-groove shape vertically cut into the substrate material metal oxide semiconductor transistor.

The "V" shape of the MOSFET's gate allows the device to deliver a higher amount of current from the source to the drain of the device. The shape of the depletion region creates a wider channel, allowing more current to flow through it.
