George Konstantinidis







FORTH participates in the project with the Microelectronics Research Group (MRG) of its "Institute of Electronic Structure and Laser" (IESL). MRG was founded in 1986 and since then it has evolved into a unique, in Greece, full-scale research facility in compound semiconductor microelectronics. It has developed a strong expertise in technology and physics of III-arsenide materials, devices and ICs through active participation in ESPRIT (Nos. 1270, 2035, 2289, 3086, 5018, 5031, 9500, 21315, 28998), RACE (No. 1027) and several national STRIDE and EPET RTD programs. Its SiC technology evolved through projects such as BRITE/EURAM 5416, NATO Sfp “HP-HF SiC power devices”, NATO Sfp “SICPIN”, a US Army ERO on SiC power devices and numerous other smaller projects. Its GaN and related compounds technology advanced through 6 IST projects (“QN laser I”, “QN laser II”, “GaNANO”, “AMICOM”, “ULTRAGAN”, “MORGAN”) and 2 major national projects. In particular, it possesses significant expertise in: MBE homoepitaxial (GaAs/GaAs, InGaAs/GaAs, AlGaAs/GaAs) and heteroepitaxial growth of dissimilar materials (GaAs/Si, InGaAs/Si, InGaAs/InP, SiC/Si, GaN/Al2O3, GaN/SiC, GaN/GaAs and GaN/Si), formation of contacts and etching of III-Vs , III-Nitrides and SiC, and fabrication and analysis of high frequency and optoelectronic devices and ICs (MESFETs, HFETs, MSM-photodetectors, MQW-modulators, laser diodes and integrated optical interconnect devices, RF MEMS, MMIC’s). To exploit its accumulated expertise, the group has recently launched a microelectronics services activity providing epitaxial wafers, processing and measurement services. The latter two are ISO 9001 certified. The excellence of FORTH is highlighted by events like the candidency for the 2002 Descartes prize for its work on RF MEMS or references to its work in international journals like Compound Semiconductor (July 2002, March 2003). In 2005 FORTH was among the winners of the Descartes prize for its work on left handed materials.

  • Contribute to the technologies for the final integration.

Key personnel:

Dr. George Konstantinidis received his Ph.D degree in Solid State Electronics from the department of Electrical & Electronic Engineering of the University of Salford, UK in 1987.  Since 1988 he has been working with the MRG/FORTH as a researcher. Since 1991 he is heading the processing research activities of the group and has extensive experience in the processing of wide band gap semiconductors. He is also coordinating MRG's effort in micromachining technology with emphasis on RF-MEMS. He has worked in two European projects BONDEC and PICMOS where he developed techniques for wafer bonding. He has participated in numerous European Union funded projects (~ 2.5MEuros). He was the project manager in the INCO-Copernicus MEMSWAVE project in which novel non-silicon RF MEMS components and circuits were fabricated at FORTH and which was among the runners up of the 2002 DESCARTES prize.  He was the scientific contact of MRG in two FP6 NoEs (AMICOM & TARGET) while now he is in running 3 ENIAC projects. Since 1997, he has established an open services laboratory and since 2000 is the ISO 9001 quality system manager.  In 2003 he received the Prize "Tudor Tanasescu" of the Romanian Academy of Sciences for his work in the RF MEMS. In 2005, he was a key member of the EXEL team that was among the winners of the 2005 Descartes prize. In 2003 he was elected to the Board of Directors of the European Microwave Association (EuMA) while in 2004 and 2007 he was elected as Vice President of the Greek Micro and Nano Society. He has supervised 7 MSc and 1Ph.D students. He has ~100 publications in refereed journals. He has 5 chapters in books and holds 1 patent.

Dr. Kostis Michelakis was born in Chania, Greece, in 1963. He graduated from the Physics Department of the University of Crete and received his Masters degree in Applied Physics from the same University. He received his PhD from the University of Athens and did his post-doc at Daresbury Laboratory in the UK. He has held posts at FORTH, in Greece and the Department of Electrical and Electronic Engineering of Imperial College London, where he conducted research on submicron-gate high-electron-mobility transistors both on III-V semiconductors and on silicon, with emphasis on the design and fabrication of MMICs.
