Both MOSFET types described below can be of p- or n-type (also known as p-channel and n-channel), but n-channel devices are the most prevalent. E-MOSFETs lack a built-in channel. Instead the drain and ...

By contrast, a lateral MOSFET's source and drain terminals are on opposite sides of the device, with the gate situated on the n-doped channel. "Diffusion" refers to the device's manufacturing process: ...
