Technical Information "Evaluation of Ion Implantation Damage in GaN using XAFS (C0472)" has been published.

It is possible to confirm the recovery of crystallinity due to irradiation defects and annealing.

Gallium nitride (GaN) is used as a material for LEDs and power devices due to its high thermal conductivity and high breakdown voltage characteristics. In its manufacturing process, the production of high-quality GaN crystals without crystal defects is required, making the assessment of damage from ion implantation and the degree of recovery an important evaluation criterion. This document presents a case study evaluating the damage caused by ion implantation into GaN substrates using XAFS. It is possible to detect disturbances in the crystal structure near the GaN surface, as well as N2 and interstitial N within the film, with high precision.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
