Electrical characterization of plasma-enhanced Cvd silicon nitride dielectric on copper
In this work, a novel metal-insulator-metal (MIM) capacitor process is introduced and integrated in a Copper Interconnect technology, whose smallest feature size is 0.18mum process, which has good yield, reliability and repeatability. The MIM uses a one-photomask process and hence is termed as the …

Kontaktlose Überwachung von Atemtätigkeit und Herzaktion mittels magnetischer Bioimpedanzmessung im neonatalen Tiermodell
BACKGROUND: Magnetic induction measurement (MIM) allows the identification of resistance in biologic tissues by alternating magnetic fields. These occur when well-conducting (blood) and poor-conducting matter (air) is moved through the thorax during heart and lung activity. As a result, allocation …
