Title:
MAGNETOELECTRIC TRANSDUCER AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3223613
Kind Code:
B2
Abstract:

PURPOSE: To provide a Hall device which eliminates crystal distortion caused by the etching step and has a small unbalance rate, high reliability, and high sensitivity.
CONSTITUTION: A part except a magnetic sensitive part 1 and electrodes on a semiconductor substrate 4 is ion-implanted, and a distortion is given to the single crystal lattice of the substrate 4 to convert it into an insulating layer 2. Upon epitaxial growth over it, the ion-implanted part does not undergo growth of single crystals, but turns into an insulating layer 2. The magnetic sensitive part 1 and electrodes form a heterojunction which maintains satisfactory crystal lattices.
