Heinrich Wolf

Title: Heinrich Wolf and His Semiconductor ESD Protection Inventions.

Introduction

Heinrich Wolf is an inventor associated with Unterschleissheim, Germany, and work on electrostatic-discharge protection for integrated circuits. His listed portfolio includes 2 patents, with inventions addressing protective device structures and transistor designs.

Latest Patents

Wolf’s patent titled “Electrostatic Discharge Device for Integrated Circuits” describes a semiconductor protection device with heavily and lightly doped regions. Its arrangement is designed so that, as blocking voltage rises, a depletion zone reaches a heavily doped region before breakdown occurs between the lightly doped regions.

His patent titled “ESD Protective Transistor” describes a transistor structure with a heavily doped p-type base and n-type emitter, alongside a collector separated from the lightly doped p-well by a lightly doped n-type region. The emitter is floating rather than connected to the base through a common electrode. The patent also notes that the doping types may be reversed.

Career Highlights

Wolf is associated with Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. His listed patent work focuses on semiconductor structures intended to protect integrated circuits from electrostatic discharge.
