Abstract
The high-voltage resistor is of the vertical type, and is formed in a chip which includes a high-voltage region and a low-voltage region superimposed on the high-voltage region, both having a first conductivity type. An isolation region, at least partially buried, extends between the high-voltage region and the low-voltage region, and delimits a vertical resistive region connecting the high-voltage region to the low-voltage region.
