Abstract
본 발명은 3중 웰을 갖는 반도체 소자에 관한 것으로, 다수의 독립된 3중 웰을 구비하고, 최상부에 있는 웰을 선택적으로 각가 다른 Vbb(Back Bias)를 인가하기 위하여 한 칩내에 두개 이상의 Vbb 전압 발생 회로를 구비하고, 독립된 웰에 원하는 특성을 제조하기 위하여 독립된 웰에 각기 다른 Vbb 전압을 인가하는 반도체 소자이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semiconductor device having triple wells, comprising a plurality of independent triple wells, wherein two or more Vbb voltages are generated in one chip to selectively apply different Vbbs (Back Bias) to the wells at the top. A semiconductor device having a circuit and applying different Vbb voltages to independent wells in order to produce desired characteristics in separate wells.
