PhD Research Fellow in SLID – Intermetallic bonding for extreme temperatures

Deadline: September 24, 2018

University of South-Eastern Norway

University of South-Eastern Norway has about 18 000 students and about 1500 employees. The university is organized in four faculties, with instruction and R&D activities on eight campuses. The main profile of the university is to provide socially relevant education, geared towards specific professions, and adapted to the requirements of the workplace, as well as to produce applied research and development.

The Faculty of Technology, Natural Sciences and Maritime Sciences has a vacancy for a position as PhD Research Fellow in SLID – Intermetallic bonding for extreme temperatures.

The position is attached to the Department of Microsystems and reports to the Head of Department. The place of employment is Bakkenteigen, Horten, Vestfold.


Applicants to the PhD position must have a Master’s degree or equivalent higher education qualifications in micro/nanosystems technology, material science, physics or similar. The applicant must have gained the degree within the date of commencement.

It is a requirement that the successful applicant is granted admission to the university’s doctoral programme in Applied Micro- and Nanosystems, which requires an average grade 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 USN. The candidate must be motivated to share his or her knowledge and cooperate. Personal suitability for the position will be emphasized.

Candidates with prior knowledge of bonding technology is preferred. Ability to perform experimental work is necessary. Candidates should be independent and responsible, have strong analytic and creative skills, possess good communication capabilities including English writing skills, be an efficient team worker and be capable of working in a multidisciplinary research environment.

Information about the position

SLID – Intermetallic bonding for extreme temperaturesSLID (Solid-Liquid InterDiffusion) bonding is a bonding technique utilizing the reaction of two metals to an intermetallic, to create strong bonds that survive temperatures much higher than the process temperature. This is important for assembly of electronics and smart systems operating at high temperatures (e.g. instrumentation for oil & gas wells, engines, gas turbines and thermoelectric generators), where traditional bonding methods such as soldering will not withstand the high temperatures. SLID furthermore has advantages of creating thin, well-defined bondlines, as well as the capability of assembly using miniaturized contacts.

Established SLID processes for material systems such as Cu–Sn and Au–Sn with processing temperatures of 232-300 oC exhibit remelting temperatures in the range 500-700 oC. The candidate shall explore non-traditional metallic systems for achieving extreme temperature performance in two different categories:

  1. Low-temperature SLID bonding, with processing temperatures of ~100 oC. This is important for the use of temperature-sensitive materials such as piezoelectric materials (e.g. for ultrasound transducers and for actuators) and polymers.
  2. Extreme high-temperature SLID bonding: Achieving remelting temperatures above 1000 oC, opens up for new applications in extreme environments such as gas turbines and thermoelectric generators. This will require exploration of more innovative combinations of metals.

The research tasks will include:

  • Identifying potential metal systems through feasibility study
  • Fabrication work in metallization and bonding
  • Characterization (microscopy, mechanical and thermal testing), and reliability testing
  • Finite element analysis

Co-operation with other research groups, as well as with relevant industry, will be part of the project work.

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

For further information concerning the position please contact Professor Knut E. Aasmundtveit, Tel. +47 31009319, [email protected] at Department of Microsystems.

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 449 400 a year. Further promotion will be based on service in the position. In special cases, employment in code 1378 may be considered. Salary NOK 449 400 – 607 700 a year. A statutory contribution will be made from the employee’s salary to the state pension plan.
