What
is IMC-Hall® ?
IMC-Hall®is
the short-form name for a magnetic sensor made of
an integrated combination of a Hall elements, electronic
circuitry and a ferromagnetic layer. The ferromagnetic
layer forms the integrated magnetic concentrator
(IMC), which is placed on the CMOS Hall ASIC chip
in a batch post process. Whereas a conventional
Hall ASIC responds to a magnetic field perpendicular
to the chip surface, a Hall ASIC with IMC responds
to a magnetic field parallel with the chip surface
 Conventional
Hall Sensor ASICs consist of a combination of Hall
elements and electronic circuitry on a silicon chip.
Due to the nature of the Hall elements such sensors
are only sensitive to a magnetic field B perpendicular
to the chip surface.
 A
single-axis IMC-Hall®
ASIC also consists of Hall elements and electronic
circuitry, but additionally it has a thin structured
ferromagnetic layer on the surface. A magnetic field
B parallel with the chip surface is rotated locally
to vertical direction under the edges of the IMC's
close to the gap, so that now it can be measured
by the Hall elements. Moreover the IMC's also function
as passive amplifiers.
 By
applying a single disk-shape IMC on the chip surface,
a two-axis IMC-Hall®
sensor is realized. Two Hall elements measure under
its edge a magnetic field component Bx (red), and
two other Hall elements measured By (blue). This
allows to make a real two-axis magnetic field sensor
for example for angular position measurement.
