Post-Doctoral Researcher in Optical Design and Advanced Packaging
(Rinn Semiconductor – Ireland’s Centre for Semiconductor Innovation – PACK Theme)

About Tyndall
Tyndall National Institute is an international leader in semiconductors, photonics and deep-tech research and innovation. As a leading collaborative European research institute, Tyndall is a key actor and hosting partner in the delivery of the ‘Chips for Europe Initiative’ (EU Chips Act).

Tyndall is Ireland’s leading research and innovation organisation and it is the national focal point for excellence in deep-tech research, development and graduate training at the convergence of nanotechnology, microelectronics, photonics, electronics and AI. Tyndall is recognised as an international research leader in semiconductor, chip and digital technologies, particularly as applied to the fields of Information & Communications, Health & Life Sciences, Agritech & Food Security, Energy and Climate Mitigation, emerging fields such as quantum, and novel computing paradigms.

The Institute’s key objective is to see frontier research activities having a significant impact on economic development and societal challenges in Ireland, Europe and beyond. Central to Tyndall’s mission is delivering economic impact through research excellence in partnership with industry and academia. With an annual turnover of more than €50m, the Institute has a community of over 600 researchers, engineers, support staff, postgraduate students, interns and industry researchers-in-residence.

With significant committed Irish government support, Tyndall will grow to be 1,000 people by 2030, with approximately 750 researchers, including 250 PhD students. A new 17,000 m2 research building is under development adjacent to the Cork headquarters and there are developing plans to expand Tyndall’s existing Dublin research labs and to establish other research sites within Ireland.

Tyndall’s expansion is also supported by recent national and EU funding wins for significant (M€10’s) additional research equipment across a range of areas such as semiconductor processing, microscopy, quantum technologies, heterogeneous integration, ultra-high speed optical communications and RF through THz characterisation.

About Rinn Semiconductor
Rinn Semiconductors is part of a constellation of seven major new centres which collectively represent an investment of €460M in advanced research by the Government of Ireland. Rinn Semiconductors aims to lead Ireland’s response to the end of Moore’s Law scaling, the point where traditional improvements in computer chips slows down or ends, by pioneering modular integrated circuit-based (chiplet-based) semiconductor design and integration. With deep expertise in the areas of Heterogeneous Integration and Advanced Packaging, the Rinn Semiconductors team propose to enable transformative advances in these technologies and to apply them in three main application areas: Future Internet, Sustainable Energy and Environment, and Digital Healthcare. A key objective of the Rinn is to foster deep collaboration across the seven universities and institutions involved, by leveraging the semiconductor fabrication facilities at Tyndall, ultimately creating a cohesive “atom to systems” value chain in Ireland, connecting everything from basic materials research through to complete technology solutions. The Rinn will operate in close collaboration with Ireland’s vibrant semiconductor industry sector which supports 20,000 high skilled jobs and includes world leading multinational companies, small and medium sized enterprises and start-ups.
