Microtronic is a leading manufacturer of components for the
world wide hearing instrument industry. In order to extend product range
and improve on component quality and price, Microtronic aims at supplementing
existing fine mechanics technology platform with modern microsystems technology
where the benefits of the batch oriented, potential cost effective and
uniform production features of this technology are present.
The actual AE deals with a microelectronic smart sensor circuit SSAPD
capable of sensing magnetic fields to determine the angular position of
a movable part producing the magnetic field from a built-in permanent
magnet. SSAPD is a full-custom mixed analogue-digital circuit made in
a low threshold voltage, double poly CMOS process. The circuit is designed
to be the sole active device in a future microsystem product PJ1000, which
is a miniature potentiometer with digital coded output to be used in the
new generation of digital hearing instruments as a volume control. The
new component PJ1000 should gradually replace a significant part of traditional,
high quality potentiometer, trimmer and switch products made by fine mechanics
and sold in quantities well exceeding 1 million per year. PJ1000 is expected
to exhibit outstanding ease of use, reliability and performance far exceeding
the quality limits of existing components.
The biggest challenge in the project has been to predict the required
magnetic field sensitivity and achieve this. On this background this AE
has been phased into 3 parts, which includes feasibility of magnetic sensing,
critical design analysis and providence of prototypes. Thus, for this
experiment more wafer runs (MPW) were planned.
The AE has a budget of kEUR 140 and duration of 17 months. This AE investment
plus the internal product development investments, amounts to approx.
900 kEUR. The pay back period is calculated as 3 years. The Return of
Investment (ROI) is 820%
