N-channel JFET
Take a N-type silicon, cut two slots at its left and right and pop in P-type semiconductor in those slots. Whats results is a N-channel JFET Ohmics contacts atr attached to the top and bottom and they serve as Drain and Source terminals. Ohmic contacts are attached to the P-type material too and they are both tied together and this is called as the gate.
