Michael Mayer, PEng

Michael Mayer is an Associate Professor in the department of Mechanical and Mechatronics Engineering at the University of Waterloo in Ontario, Canada. From 2000 to 2004 he was a senior R&D engineer with a semiconductor equipment manufacturer, ESEC, in Switzerland. He received a diploma (masters) degree in Physics in 1994 and a PhD degree in Technical Sciences in 2000, both from the Swiss Federal Institute of Technology (ETH) Zurich.

Michael has prior experience as a senior process engineer, project leader, and intellectual property responsible. Since joining the University of Waterloo, Michael has conducted projects with several companies including Microbonds Inc., MK Electron, Bosch, Oerlikon, Intel Corp., Kulicke and Soffa, Orthodyne Electronics, Futurewei, Microfab AG, Montfort Lasers, and others. Michael is serving on the executive committee of the IEEE Electronics Components and Technology Conference.

Michael has co-authored many technical publications and patents. He has developed improved bonding methods and various microsensor tools for diagnostics of processes and reliability of microjoints and more recently has been working on direct bonding and laser joining of biological materials.

Miniaturized joining (microjoining) processes are essential to microelectronics and include microelectronic soldering and ultrasonic wire bonding. In our research, we contribute e.g. to the identification and description of processes and reliability, real-time monitoring of mechanisms during microjoining using e.g. custom developed ultrasonic sensors, and numerical modeling. Microjoining is also important for the automotive, medical devices, and aerospace industries. Welding biological materials with laser has promising applications in surgery. There is a need for practical solutions e.g. when sealing living skin of organs after surgery or e.g. for improved repair-processes for vessel ruptures. We are working towards studying how parameters such as laser energy, auxiliary process materials, and inventive mechanical setups can assist laser joining (laser welding) of biological materials. Direct Bonding is the joining of two components based on atomic bonding of its surface atoms. For direct bonding to be successful, the faying surfaces must be sufficiently smooth, flat, and clean. It can be extremely tricky to achieve these requirements. Nevertheless, direct bonding promises for improvements in the fields of photonics and 3D integrated circuits. We are working towards direct bonding processes for optical glasses for the subsequent production of more economical solid state lasers.

Graduate researchers in Michael’s group conduct experimental, analytical, and numerical investigations. They work with new materials, methods, and theories, and collaborate with other research groups on campus. Students and postdocs out of Michael's group were hired by companies like Microbonds, Kulicke and Soffa, Samsung, Bell, Telus, Government of Canada, Analog Devices, Tesla, Meta, Qualcomm, Nvidia, Google, SK Hynix, etc.
