Sabanci University IHP Microelectronics Joint Virtual Lab
Sabancı University and the leading German scientific center IHP-Microelectronics establish a first in Turkey: the Microelectronics – Joint Virtual Excellence Lab based on the “More-than-Moore” concept.
The Microelectronics Research Group of the Sabancı University Faculty of Engineering and Natural Sciences has been undertaking successful cooperation projects with the leading German scientific center IHP-Microelectronics since 2008. The two cutting-edge institutions now join their scientific experience and resources in a Microelectronics – Joint Virtual Excellence Lab based on the “More-than-Moore” concept. This initiative is expected to take scientific studies to a new level that is novel to Turkey and rare abroad as well, leading to more effective studies both in Turkey and on a European level. The motto of the More-than-Moore concept is to develop smaller, functional, economical, versatile and long-lasting electronic systems. This has potential to contribute to many industries including communication, biomedicine, aerospace, aviation, security, automotive and robot-automation.
The lab was established at the signing ceremony and conference held at the SUNUM facility on the Sabancı University Tuzla campus on Thursday, October 16, 2014, hosted by Sabancı University President Professor Nihat Berker and attended by IHP-Microelectronics Rector Professor Bernd Tillack, the German Federal Ministry of Education and Research, and representatives from the Turkish Ministry of Science, Industry and Technology, TÜBİTAK, and related sectors.
The Joint Lab bundles the expertise of both academic institutions. The focus is on the exploration and development of mm-wave integrated circuits. The main objective is extending the research capabilities by using a complementary research approach and increasing international visibility. Since 2014, more than 45 undergrad and grad students from Sabanci University have had the opportunity to perform their internships at IHP. They have provided significant contributions to the joint research, with contributions to the academic publications during their bachelor study. Some of the students are continuing their PhD studies at IHP after their successful internship period. The Joint Lab has succeeded in receiving funds from the Turkish Government funding agency, TUBITAK, for cooperation and joint development on RFMEMS technologies. Today, the Joint Lab cooperation is not only based on student exchange, but also on exchange at the senior researcher level. During the summer of 2019, 11 students from Sabanci University have performed their internship at IHP (see Figure). Out of the research they have done during the internship, they have contributed to an academic publication as coauthors.
The research and development-focused cooperation of IHP-Microelectronics, a major technology provider to the leading wireless communication companies of the world, and Sabancı University is the first example of a pioneering model in Turkey. The IHP - Sabancı University Joint Virtual Lab – Center of Excellence will enable easier access of other universities, research institutions and companies in Turkey to research and development in the field, serving to increase cooperation.
The objectives of the Sabancı University and IHP-Microelectronics Joint Virtual Excellence Lab are:
Extending the research capabilities by using a complementary research approach; strengthening the position for joint project applications; increasing international visibility; attracting excellent students and researchers for joint project work; and bringing in high level teaching (lectures, internships at IHP, and visiting scientists) based on advanced IHP and Sabancı’s research topics.
Supported by the technological infrastructure and knowhow of Sabancı University and IHP-Microelectronics, the ‘Center of Excellence’ will help to demonstrate successful German Turkish cooperation on scientific as well as political levels.
"It is our goal is to strengthen the cooperation between Turkey and Germany in the fields of science and research. Therefore, I expressly welcome the special commitment of the IHP-Leibniz Institute for Innovative Microelectronics in Frankfurt (Oder) and the technological cooperation with its partner in Istanbul. I wish both partners every success in their cooperation," said the Federal Minister of Education and Research, Johanna Wanka. "This cooperation reflects the aim of the German-Turkish Year of Science 2014, namely the further expansion of joint activities in research, education and innovation with projects that point the way to the future.".

The main research areas:
Complementary research approach
Sabanci University MicroElectronics Research group (SUMER) and IHP-Microelectronics are currently carring out three different projects under jointly established virtual lab.
Project 1: Development of High TCR Multiple Quantum Well (MQW) SiGe Microbolometer Arrays for High Performance Infrared Imaging Systems
By being used in uncooled systems, microbolometers hold more than %90 of share in the infrared imaging market. Temperature-Coefficient-of-Resistance (TCR), as a measure of performance, is very important for the sensitivity of the microbolometer array. In this project, 5.5%/K TCR value is achieved through the use of 50% Ge concentration together with some special carbon-delta layers and doping profiles. Multiple Quantum Well (MQW) type detector arrays in mono-crystal Silicon Germanium (SiGe) process that are highly sensitive to thermal changes are used. Full custom integrated circuits with array dimensions of 80x60 and 320x240 are designed, fabricated, and verified in the scope of the project. Finally, a flexible imaging module that is compatible with many imaging systems is designed and verified, which enables to generate various supply and bias voltages and control signals. Improving the TCR of SiGe MQW detector performance while keeping the noise low significantly contributed to the state of the art. 4 journal papers 4 conference proceedings are published in respected journals as part of the project. 1 PhD thesis is also accomplished in the scope of the project. The developed low cost microbolometer technology is intended to be used in civilian night vision systems and will have an economic impact in that respect.
Project 2: SiGe BiCMOS Technology Based Monolithic 140 GHz and 240 GHz (THz) Frontend Circuits
Aim of the project is to develop 140 GHz centred power and Dicke radiometers and 240 GHz voltage control oscillators by using the RFMEMS switches in a 0.13 um SiGe BiCMOS process. In this project, RFMEMS switches play a crucial role in 140 GHz radiometers due to the low insertion-loss and also play a crucial role in 240 GHz voltage-controlled oscillators due to the variable capacitance performances. Design and fabrication of other sub-blocks such as low noise amplifiers, power detectors, and single-pole-double-throw switches are also designed in this project to build a radiometer system. 1 journal papers and 4 conference proceedings are published in respected journals as part of the project. 1 MSc thesis is also accomplished in the scope of the project.
The cooperation strategy between IHP and Sabanci University is planned using 4 main paths:
The mutual development of grad level course contents and/or new courses with respect to the hot research topics is one of the main strategic path of the cooperation. To share the know-how and the increase the synergy is the second strategic path of the IHP-Sabanci cooperation. This includes both academic and student level short term and long-term exchanges. The achieved scientific excellence in the first two strategy paths are used to perform a breakthrough research and innovation, under the third strategic path, “Research and Development”. The ultimate goal of the cooperation between IHP and Sabanci University is bringing the joint academic and scientific experience into the prototyping and commercialization level by close cooperation with industry, both on Turkey and Germany sides.
