Planar-type Hall-effect sensor IP ready for foundries

The Hall-effect sensor was suitable for high sensitivity and low-corner frequency, and is only 50x50um2 in size. The initial products had a Hall resistance of 2.4K ohms, sensitivity of 44.5mV/VT and a corner frequency of 500Hz. Most of all, it was recognized for its robustness and stability against noise. With outstanding features, the initial products were well adopted in the market and this in turn prompted MagnaChip to provide the planar-type Hall-effect sensors to its existing and potential foundry customers. The Hall-effect sensor IP can be easily integrated into a customer’s design by adding only one mask to various processes that the foundry already offers. In addition, the integration of the Hall-effect sensors can be made without making any changes in electrical characteristics and it is offered regardless of the technology node, ranging from 0.13um to 0.35um. The process design kit (PDK) provides P-cell and Verilog-A model, with availability to a temperature of up to 150ºC to ensure a wider use in diverse applications, such as the fast growing IoT and automotive markets.

MagnaChip is currently developing a vertical Hall-effect sensor with the direction of the magnetic field parallel to the silicon surface, which enables 3 dimensional Hall sensing capabilities.
