Leader in Integrated ICT Hardware & Systems

Researcher Magnetic Materials

PMcC-8 Researcher Magnetic Materials - Integrated Magnetics

Contract: Full Time/Fixed Term

Background
The trend toward miniaturisation and ever increasing functionality for portable electronic devices is creating new challenges in the fields of electronic engineering, materials science and process development.  A key performance requirement for portable devices is battery life and this can be significantly extended by using a “granular” power supply approach that enables unused functions in the system on chip (SOC) to be switched off. However this requires many miniaturised efficient power converters. In order to limit the output current ripple, power converters require energy storage and usually magnetic devices such as inductors and transformers fulfil this requirement. Traditionally, these magnetic components tend to be very bulky but for switch mode power conversion the value of the inductance required is reduced by using a high switching frequency (20 – 200 MHz).  This makes the footprint of integrated magnetic devices feasible but requires magnetic material and devices that can operate efficiently at high frequencies.   

Tyndall National Institute at University College Cork, has over the last decade, been a recognized world leader in the area of integrated magnetic components for electronic applications.   Prof. Ó Mathúna from Tyndall, is the founder of the International Workshop on Power Supply on Chip and a Fellow of the Institute of Electrical and Electronics Engineering (IEEE) in the field of power electronics with the citation “for leadership in the development of power supply using micromagnetics on silicon”. In 2015, the Magnetics on Silicon researchers were selected as the UCC Research Team of the Year.  Tyndall Integrated Magnetics research has demonstrated:-

  • Highest efficiency for micro-inductors
  • Micro-inductors in dc-dc converters up to 100MHz 
  • Highest efficiency coupled inductors
  • Highest voltage gain & efficiency for micro-transformers
  • First CAD tool for power micro-inductors 
  • First high frequency integrated power magnetics using pulsed reverse electroplated magnetic material


In addition to integrated magnetics on silicon, Tyndall’s Integrated Magnetics research has addressed PCB embedded magnetic devices. To the present, a magnetic core is provided for both types of integrated devices using electrodeposited magnetic material and windings are fabricated for; magnetics on silicon devices using electrodeposited copper and for pcb embedded magnetics using internal copper tracks.
Tyndall has recently obtained more than €3m funding from Science Foundation Ireland (SFI), EU Horizon 2020 and Enterprise Ireland for further world class pioneering research and commercialization of its Integrated Magnetics technology. The SFI Principal Investigator funding obtained by Prof. Ó Mathúna is one of 24 such awards in Ireland.  As a result of this funding, Tyndall is planning a number of strategic hires to expand the existing team.  


Job Description

Reporting to the Senior Researcher in magnetics materials the post-doctoral researcher in magnetics materials, will play a leading role in the delivery of world-class outputs and the generation of economic impact from research excellence in integrated magnetics devices and associated circuits. This post-doctoral position will help advance the development of a new generation of integrated magnetic devices, with increased efficiency and miniaturisation.  A major part of the research will focus on the development of improved nanostructured / amorphous magnetic materials with reduced high frequency losses.  Material synthesis will use microelectronics compatible technologies i.e. sputtering or electrodeposition. The magnetic materials will also have to be compatible with being part of a laminated core structure.  The post-doctoral researcher will participate in research collaborations with both academic and industrial partners and contribute to the sourcing of research funding from industry as well as Irish, European and international research agencies. They will also contribute to the continued development of a ‘high engagement/high performance working environment amongst all staff by promoting Tyndall’s key values of Leadership, Excellence, Teamwork, People, Entrepreneurship and Optimism.

Key Responsibilities

  • Undertake research in the development and characterisation of novel sputtered and electroplated thin film magnetic materials.
  • Undertake research in the development and characterisation of laminated magnetic core structures.
  • Initiate, participate in and manage key research projects. This includes support with the preparation of project deliverables, including technical reports, publications and the delivery of prototypes, as well as providing direct technical support to other group members using their knowledge and background in MEMS and systems integration technologies.
  • Disseminate research results to research partners as well as scientific and engineering communities as appropriate
  • Participate in the generation, management and commercialization/technology transfer of Intellectual Property.
  • Engage in the procurement of research funding from agencies including Enterprise Ireland, Science Foundation Ireland, EU as well as direct industry collaborations including the estimation of costs, resource requirements and schedules as well as supporting the preparation of contracts.
  • Represent the Group in national and international fora, as required.
  • Ensure compliance with Tyndall’s Quality Management system and Health and Safety standards.
  • Carry out additional duties as may be reasonably required within the scope and level of the post.
