Title: Pieter J Jochems: Innovator in Semiconductor Technology

Introduction

Pieter J Jochems is a prominent inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on developing high-speed, low-power-dissipation integrated circuits, which are crucial for modern electronic devices.

Latest Patents

One of his latest patents involves a method of manufacturing a semiconductor device that features an integrated circuit in an epitaxial layer on a substrate. This innovative method includes islands of conductivity type opposite to that of the substrate, surrounded by a region of the same conductivity type. The bipolar transistor is integrated within at least one island, and the p-n junctions are oriented at right angles to the surface. This invention is vital for creating compact and fast circuits with low power dissipation, combining CMOS and bipolar subcircuits.

Another notable patent describes a method of making semiconductor devices by forming an impurity-adjusted layer. In this process, semiconductor circuit elements are created through diffusion from buried layers into an epitaxial layer. The resulting surface layer maintains the same doping as the original epitaxial layer, serving as a reference for insulated gate field effect transistors. This method is particularly important for determining threshold voltages in CMOS circuits with adjoining 'twin tub' regions.
