Thermal Transient Measurements of GaN HEMT Structures by Electrical Measurements
Paper i proceeding, 2023
The thermal transient behaviour of GaN HEMT structures is studied using an integrated sensor placed in the close vicinity of a heat source. It is demonstrated that the method can extract time constants in the μs range for a 5 μm separation between the sensor and heat source. The study includes measurements that show how lateral separation, dissipated power, and proximity to the edge of the chip impact the temperature increase of a device. It is concluded that the method is promising for calibrating numerical models and evaluating packaging solutions.
