Abstract
A junction field effect transistor comprises a semiconductor substrate. A first impurity region of a first conductivity type is formed in the substrate. A second impurity region of the first conductivity type is formed in the substrate and spaced apart from the first impurity region. A channel region of the first conductivity type is formed between the first and second impurity regions. A gate region of a second conductivity type is formed in the substrate between the first and second impurity regions. A gap region is formed in the substrate between the gate region and the first impurity region such that the first impurity region is spaced apart from the gate region.
