DEFINITIONS

• A semi conductor magnetic sensor is a sensor that detects magnetic field and converts it into an electric signal.

• Position of magnetic sensors in the supply chain :

Second level

packaging

Sensor

packaged

• First level packaged magnetic sensor are integrated into second level packaging (often the case in automotive or industry) ordirectly integrated into PCB of electronic systems such as mobile phones, white goods… A magnetometer is a standalonesystem that provides magnetic field value.This name is also often used for first level sensors in ecompass applications.

• First level sensor include the magnetic sensor (called also bridge) + ASIC option in a ceramic package with connectors.

• Most of time first level packaged sensor includes an ASIC. In few cases, the sensor is sold without ASIC that is addedafterward by the integrator.ASP is thus considered with ASIC.ASP without ASIC is 3 to 4 times lower.

• Chip will be monolithic (sensor+ASIC) or in multi chips packages (MCP).

MAGNETIC SENSOR TECHNOLOGIES

GMR sensors

• Giant Magnetoresistance is a quantum mechanical magnetoresistance effect observed in multilayers composed of alternating ferromagnetic and non-magnetic conductive layers. Effect discovered in 1988.

• Most common GMR structure is the spin-valve structure containing 3 main layers:

• 2 layers of ferromagnetic (FM) thin layer material

• A conducting non-ferromagnetic (NM) interlayer separate the ferromagnetic layers (about 3 nm thick)

• GMR magneto resistive ratio is about 4 times larger (12%) than AMR => more sensitive than AMR and Hall

• GMR monolithically integrated is available in ecompass high volumes application by xxx (JP) and xxx(JP).

MAGNETIC SENSORS VALUE CHAIN

Who is working with whom in automotive applications ?

Supply chain tends to fragment with more recent technologies (xMR)

• Vertical integration dominate for the top players focused on Hall monolithic technology whereas for xMRtechnologies which are more recent, multichip approach is favored and some players prefer to outsource the sensorsupply (Sensitec).
