Abstract
Embodiments relate to the field of semiconductors, and provide a semiconductor device and a method for manufacturing the same. The semiconductor device includes: an active pillar including a channel region and a source/drain region arranged on two sides of the channel region; and a gate structure surrounding at least part of the channel region. The channel region includes a peripheral portion and a central portion, the peripheral portion is positioned between the gate structure and the central portion, the source/drain region and the peripheral portion have a first doping type, and the central portion has a second doping type, where the first doping type is one of N-type and P-type, and the second doping type is other one of the N-type and the P-type. At least problems of greater difficulty in turning off existing junctionless field effect transistor and poorer turn-off effect may be solved.
