Title: Voltage-regulator diode
Inventor: MIYAOKA FUMIO
IPC: H01L29/866
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a voltage-regulator diode having the low output voltage and the zero or positive temperature coefficient. SOLUTION: When a semiconductor substrate 12, a base diffusion layer 13 forming the base/collector junction and an emitter diffusion layer 14 forming the base/emitter junction are formed by the diffusion from the surface of the semiconductor substrate 12, they are constituted so that the value of the current amplification factor when a reverse transistor is operated temporarily exceeds 1.0. Then, the base diffusion layer 13 is set at a floating potential.  When the base-collector junction is biased in the forward direction and the base-emitter junction is biased in the reverse direction and a current is made to flow, the output voltage generated between the emitter diffusion layer 14 and the semiconductor substrate 12 is made smaller than the value, which is the sum of the single forward dropping voltage of the base/collector junction 21 and the single breakdown voltage of the base/emitter junction 22. Thus, the output voltage can be adjusted by controlling the current amplification factor, the temperature coefficient of the breakdown voltage of the base/emitter junction 21 is adjusted and the zero or positive temperature coefficient can be obtained even at the output voltage of 5.5V or less.
