IFI is Norway’s largest university department for general education and research in Computer Science and related topics. The Department has near 950 students on bachelor level, near 450 master students, and over 180 PhD students. The overall staff of the Department is close to 250 employees, about 200 of these are full time positions. The full time scientific staff is 60, mostly Full/Associate Professors.

Postdoctoral Research Fellowship in 3D Sequentially Integrated ADC and Sensor Front-End Design

A position as Postdoctoral Research fellow (position code 1352) is available at the Nanoelectronics Group, Department of Informatics.

The fellowship will be for a period of 3 years, with no compulsory work or for a period of 4 years, with 25 % compulsory work (teaching or other responsibilities at the department) contingent on the qualifications of the candidate and the teaching needs of the department.

Starting date from 01-Jan-2018 and no later than 01-Mar-2016.

No one can be appointed for more than one fixed-term period at the same institution.

Project description:

The position is part of the European 3D-MUSE project that wants to use emergent sequential 3D integration technology for high performance mixed-signal integrated circuits.

The IoT is composed of connected devices that are characterized by their interaction with the environment via a plethora of sensors and actuators. The trend goes to ever more complex interactions and thus an increase in the number of different sensors integrated in the same product, which in turn requires the processing capability to handle all of those sensors.

At the same time those systems are expected to still perform on an ever lower power budget, preferably so low as to be able to operate purely on power scavenging. And of course the cost needs to be moderate too. The electronics at the heart of such a system needs to be mixed-signal electronics that interfaces to the analog sensors and actuators, but can also provide the necessary digital processing power.

3D-MUSE wants to spearhead the progression from what we shall refer to as 'systems-in-stack' to true 'systems-in-cube' (SinC) that monolithic/sequential 3D integration will enable. We define the former as a 3D system that is characterized by locating functional blocks within a single plain in the (typically parallel/wafer-bonding) 3D integration stack, while the latter makes use of the full emancipation of the interconnect density in the third dimension of sequential 3D integration and rather implements functional blocks in a volume comprising multiple tiers. We shall demonstrate this concept by conceiving novel architectures for micro circuits in a volume in a two tier 3D sequential integration process. In particular, we have identified mixed-signal circuits as, on one hand, a major bottleneck for functional performance scaling of sensor nodes and smart sensors in the IoT and cyberphysical systems, and on the other hand, excellent candidates for beneficial trade-offs when implemented as circuits in a volume with using two specialized tiers, one for analog device options and another for optimal digital designs. We shall refer to such a technology as 3D 'multi-process' sequential integration.

The goal of this position is to design SinC circuits to implement smart sensor interfaces (SSI) for specific applications.

One application shall be sensor interfaces for the ongoing sounding rocket campaigns into the ionosphere that UiO is participating in, 4DSpace - Strategic Research Initiative and The Grand Challenge Initiative – CUSP project. Specific sensors shall be for example Langmuir probes (measuring electron density in plasma) and E-filed probes. Miniaturization and energy efficiency are very important here specifically for small wireless sensor platforms that are ejected by these rockets in flight.

Another application are image sensors, where sequential 3D integration is expected to lead to a breaktrough in parallel and high speed image read out and processing. A pioneering example using parallel integration, i.e. a system-in-stack approach is the Sony Exmor series of image sensors. True SinC designs have the potential of carrying the concept of parallelism in image sensors a significant leap further.

Requirements and qualifications:

The Faculty of Mathematics and Natural Sciences has a strategic ambition of being a leading research faculty. Candidates for research fellowships will be expected to be in the upper segment of their class with respect to academic credentials.

Applicants must hold a PhD degree or equivalent in microelectronics or similar subjects with experience in analog/mixed-signal ASIC design in CMOS technology. Prior experience with sensor front end, ADC, image sensors, low power design and other relevant areas for the specific project context will be an advantage. If you will finish your PhD degree before Dec 31st 2017 you are also allowed to apply. Add the transcripts of the status of your studies now and you will be asked to supply your final degree’s documentation later.

The main purpose of post-doctoral research fellowships is to qualify researchers for work in top academic positions within their disciplines. Please also refer to the regulations pertaining to the conditions of employment for post-doctoral fellowship positions.

Please see the guidelines and regulations for appointments to Postdoctoral fellowships at the University of Oslo.

We offer:

  • Salary NOK 517 700 - 569 000 per year, depending on qualifications and seniority.
  • A professionally stimulating work environment.
  • Attractive welfare benefits and a generous pension agreement, in addition to Oslo’s family-friendly environment with its rich opportunities for culture and outdoor activities.
