AI Technical Summary

Technical Problem

Conventional methods face challenges in depositing GMR and TMR elements on the same substrate due to their different layer structures, making it difficult to fabricate magnetoresistance sensors with optimal sensitivity and noise characteristics.

Method used

The development of a magnetoresistance assembly where GMR and TMR elements are deposited over the same substrate, allowing for simultaneous electrical activation and response to magnetic fields, with TMR elements providing higher sensitivity for smaller fields and GMR elements for higher fields.

Benefits of technology

This approach simplifies fabrication, enhances sensitivity, and extends the operating range of magnetic field sensors by leveraging the complementary strengths of GMR and TMR elements, while reducing manufacturing complexity and cost.
