Title:
PROTECTIVE DIODE FOR PROTECTING SEMICONDUCTOR SWITCHING CIRCUITS FROM ELECTROSTATIC DISCHARGES
Document Type and Number:
WIPO Patent Application WO2005081308
Kind Code:
A3
Abstract:
The invention relates to an arrangement of a protective diode for protecting semiconductor switching circuits from electrostatic discharges. The aim of the invention is to create an arrangement by which means improved ESD protection with optimum chip surface use and an improved latch-up behaviour can be achieved. To this end, the planar diode consists of a first insular electrode surrounded by a second electrode, the contacts of the first electrode being contacted by a first metallic plane, and the contacts of the second electrode by a second, superimposed metallic plane.
