Recording | AuSn Thin Film Technology and AuSn Pre-deposited Substrates for Optoelectronics


On Oct 20th at 9:00 pm Beijing time (1:00 pm UK standard time), Focuslight joined Electro Optics in a webinar session.

Allen Liu, Senior Product Line Manager of Advanced Materials from Focuslight's Diode Laser BU, gave a presentation entitled "AuSn Thin Film Technology and AuSn Pre-deposited Substrates for Optoelectronics".


AuSn thin film is a critical technology to ensure the long-term reliable use of optoelectronic devices. Compared to traditional materials such as Indium, SnPb, SnBi etc., AuSn bonded devices have superior performance in durability, oxidation resistance and thermal fatigue resistance. In this session, Allen Liu, Senior Product Line Manager of Advanced Materials from Focuslight’s Diode Laser BU, will present the design and key process of AuSn thin film, combined with application data of high-power diode laser devices. It will be a detailed introduction to AuSn thin film technology and AuSn pre-deposited substrates for optoelectronics from the application point of view.
