Senior Research Engineer - Wafer Bond (all genders)

Are you ready to drive cutting-edge wafer bonding technologies? Join our wafer-level packaging team and help pioneer innovative processes for bonding and debonding wafers, enabling the development of next-generation 3D and heterogeneous integration technologies.

Your future tasks include:

• Development and optimization of wafer bonding processes for advanced packaging and heterogeneous integration
• Operation and ownership of wafer bonding equipment (wafer bond cluster line as well as stand-alone wafer bonder)
• Process development for permanent and temporary wafer bonding techniques such as metallic, adhesive, anodic, glass frit, hydrophilic and surface activated bonding (SAB)
• Pre-bond surface preparation including lithography, plasma activation, and wafer cleaning processes
• Integration of bonding processes into microfabrication flows in cleanroom environment
• Characterization of bonded interfaces using bond metrology tools (e.g. void inspection, strength testing, alignment accuracy)
• DOE planning, process control, and yield improvement
• Data analysis and documentation of process performance
• Contribution to internal and collaborative R&D project
• Technical reporting and support in scientific publications

Your profile:

• University degree in Microfabrication, Physics, Electronics, Materials Science or a related field.
• Minimum of five years' hands-on experience in cleanroom processing and semiconductor fabrication. 
• Proven track record in wafer bonding process development and optimisation
• Experience as a tool owner for wafer bonding systems (cluster tools are strongly preferred).
• Strong practical experience with lithography, plasma activation and wafer cleaning
• Hands-on experience with both permanent and temporary bonding techniques
• Solid knowledge of W2W and D2W bonding approaches (sequential and collective).
• Experience with multiple bonding technologies: anodic, glass frit, metallic, adhesive and SAB 
• Familiarity with bond characterisation and metrology techniques
• Understanding of surface chemistry and interface physics relevant to bonding
• Strong problem-solving skills and process-oriented thinking
• Experience in DOE, statistical analysis and process control is advantageous.
• Ability to work independently in a clean room and as part of a multidisciplinary team
• Fluency in English; German is a plus
