| 摘要 |
The present invention relates to a semiconductor device having a magnetic sensor for detecting a magnetic direction. A stress due to the magnetic focusing plate of a magnetic material is low. The magnetic sensor comprises a hole device installed on the surface of a semiconductor substrate and a magnetic focusing plate covers at least part of the hole device, respectively, and is made of a magnetic material having a magnetic amplification function. The magnetic material incudes a slit or slot so that a stress generated in the hole device can be prevented. |
