GaN HEMT epiwafers
High-power ICs (integrated circuits) and high frequency communication ICs with high efficiency and low power dissipation are in great demand. NTT-AT provides high-quality GaN epitaxial wafers that satisfy the challenging requirements of such products. We produce epitaxial wafers which we insure are aligned with the design concepts of IC chip manufacturers. In addition, we are constantly engaged in essential consideration of leakage current reduction and collapse reduction by precisely controlling epitaxial growth conditions and maintaining a stable process based on know-how and many years of accumulated technology, inherited from NTT laboratories. We have prepared a wafer production system appropriate for the requirements of high uniformity for R&D, and stable mass production of commercial products. NTT-AT is not an IC chip manufacturer, but NTT-AT has knowledge of IC chips from its research activities. NTT-AT is a partner of IC chip manufacturers and attentively supports them as customers. Please feel free to discuss with NTT-AT about GaN HEMT epitaxial wafers.
