The Faculty of Technology, Natural Sciences and Maritime Sciences have a vacancy for a position as PhD Research Fellow in Applied Micro- and Nanosystems - Transducer Technologies

About the position

The Faculty of Technology, Natural Sciences and Maritime Sciences has a vacancy for a temporary 100 % position as PhD Research Fellow in Applied Micro- and Nanosystems from 01.09.2021.

The position is located at the Department of Microsystems and reports to the Head of Department. The place of employment is campus Vestfold in Horten.

Appointment is for a period of three years. The position does not include teaching duties.

About the PhD-project

The PhD research fellow is a part of an on-going research project focusing on transducer technologies for the next generation of advanced medical ultrasound probes. This project is a collaboration between USN and GE Vingmed Ultrasound AS with the support from the Research Council of Norway.

The research interest of this project is the transition from conventional ceramic-based to micromachined ultrasound transducers. Assembly and integration of the micromachined ultrasound transducers is challenging due to its physical properties. The research of the PhD candidate includes several of the following topics:

  • Assembly and integration technologies for micromachined ultrasound transducers and driver electronics, both at die-level and wafer-level.
  • Characterization of the assembled devices in terms of electrical, acoustical, mechanical performance as well as reliability related to ultrasound applications.
  • Integration of conventional ceramic-based and micromachined ultrasound transducers into ultrasound scanner to compare its performance with exisiting technology.


Applicants to the PhD position must have a Master’s degree (120 ECTS) or equivalent higher education qualifications in microsystem technology, system integration, electronic engineering, material science, physics or closely related subject.

The degree must be accomplished within the commencement date.

It is a requirement that the successful applicant is granted admission to the university’s doctoral programme in Applied Micro- and Nanosystems within three months of accession in the position, which requires an average B from Master's degree, in addition to grade B at the final master project.

Co-operation between staff members is an integrated part of the working atmosphere at the University of South-Eastern Norway (USN). The candidate must be motivated and demonstrate a proven ability to work effectively within a team and in a collegiate manner to formulate and realise common objectives.

Personal suitability for the position will be emphasized. The successful candidate will be part of the research groups "Ultrasound Transducers" and "Materials and Micro-integration" at USN-IMS. The groups have long experience with ultrasound transducer technologies and packaging technologies including materials, assembly, characterization and testing. The groups has substantial collaboration with industrial partners in Norway as well as international partners.

Specific requirements for the position are described below:

  • We are looking for a person with knowledge and experience in several of the following fields: assembly and integration of MEMS devices (die-level and/or wafer-level), ultrasound transducers, microsystems, material sciences, physics, electronics, characterization techniques, testing.
  • Ability to perform experimental work is crucial. Ability to perform computer modelling such as final element modelling is an advantage.
  • Good analytical and theoretical skills, as well as creative thinking and communication skills are advantageous.

Applicants are required to provide evidence of good English language skills, both writing and speaking. Applicants outside the Scandinavian educational system may use one of the following tests as such documentation: TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).

We offer

  • A professionally stimulating working environment
  • Good opportunities to develop your career and your academic skills
  • A good social environment
  • Attractive welfare benefits in the State Pension Plan
  • Opportunity for physical activities within working hours


PhD Research Fellow (code 1017): NOK 491 200 a year. Further promotion will be based on time served in the position. In special cases, employment in code 1378 may be considered.

A statutory contribution to the state pension plan will be deducted from the employee’s salary.
