SK keyfoundry, an 8-inch pure-play foundry in Korea, announced today that it offers a new 3D Hall-effect sensor technology that can measure speed and direction through three-dimensional magnetic field detection for its foundry customers.

The Hall-effect sensor is a device that measures the strength of a magnetic field using the Hall-effect, which detects the voltage difference generated when a conductor or semiconductor passes through a magnetic field. The measured magnetic field is utilized in applications that leverage the position, speed, rotation, direction, and current of devices.
