| Research Abstract |
In order to estimate the magnetic properties of superconducting materials, the three-axis magnetic sensor with small size and planar structure is necessary. We propose the novel fabrication technology of three-axis magnetic sensor based on Hall sensor using semiconductor film bonding technologies, in which the GaAs semiconductor film was released from mother substrate, and bonded it on the metal electrode surface formed on the dielectric or Si substrate, and x, y, z axis Hall sensor was fabricated. We investigated the process conditions such as the fabrication conditions of through substrate Via, fabrication conditions of three-axis Hall sensor, and estimated the basic characteristics of the three-axis Hall sensor. The results indicated possibility of the technology.
