A position as Research is available at the Nanoelectronics Group, Department of Informatics.

The position will be for a period of up 2 years. End date of the project is 31.12.2021.

Starting date from 01.January 2020 and no later than 01.March 2020.

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 (see http://www.mn.uio.no/fysikk/english/research/projects/4dspace/ and http://www.grandchallenge.no/). 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.
