As International Semiconductor Team (IST), our team is composed of researchers with experience and background in physics, chemistry, biology, material science, electronics, and other related fields. The purpose of our team is to develop and fabricate semiconductor-based sensors for industrial platforms while researching and investigating sensors for various applications. The IST team has significant experience in designing and installing the infrastructure required for the production of semiconductor sensors and devices, starting with clean room construction. As the IST team, it has extensive experience and knowledge in designing semiconductor devices, producing devices, testing and characterizing them, packaging the device and testing the final product, starting with simulation (TCAD) work for industrial and R&D applications. Although the main work area of our team is the design, production and development of radiation-sensing MOSFETs (NürFETs) and Photodiodes, we as a team have more than 10 years of experience and knowledge in production, development and design of many different semiconductor-based sensors (PIN Photodiodes, Temperature sensors, Biosensors, LEDs and BJTs).
- NUCLEAR RADIATION SENSING FIELD EFFECT TRANSISTORS (NÜRFETS)
NürFETs are p-channel MOSFETs specially designed for radiation detection. NürFETs offer new opportunities for small radiation detection systems, thanks to their small size. Compared to other detector systems, the NürFET system is compact and easy to integrate into systems due to its low energy consumption. NürFETs are used as radiation dosimeters in medical applications, military and security applications, nuclear power plant applications, and space applications. NürFETs produced in our “TÜBİTAK 2508 Slovenian Bilateral Cooperation” project will be used in nuclear reactors with high radiation fields. At the same time, the tests of the NürFETs produced in this project were used in the ATLAS experiment at CERN. The first results showed that NürFETs were more efficient than their counterparts. Within the scope of our “TÜBİTAK 1005 B-NürFET” project, thermal neutron sensing boron layer NürFETs will be produced. In this way, it will have an important place in nuclear reactor applications, defense, and security applications.
- PIN PHOTODIODES
PIN photodiodes are photodiodes that contain a P-I-N semiconductor structure. This technical approach has some advantages over PN diodes. An optical detector is a device that converts light signals into electrical signals that can then be amplified and processed. These structures can be used as nuclear radiation sensors. PIN photodiodes to be produced in our “TÜBİTAK-SDF” and “TÜBİTAK 1505” projects will be used in medical applications, especially in radiotherapy, for measuring the doses that patients should receive and as a personal dosimeter. PIN photodiodes will also be used for radiation measurements in nuclear reactor applications. Another area of use is that it is used in missile tracking mechanisms and has a function in defense and security applications.
- TEMPERATURE SENSORS (PLATINUM/NICKEL BASED RTDS)
Within the scope of the project, domestic temperature sensor production was carried out. In today's world, temperature sensors are used everywhere from small household appliances to giant industrial establishments. 39% of the world's total sensor needs are temperature sensors. It is aimed to increase the change per unit temperature of this product, which is produced only in Germany and has a very high added value, and to be produced locally in our country, and it has been produced successfully. Temperature sensors tested and approved by the Cooking Appliances Plant R&D Center in Arçelik A.Ş. are compared with commercially available temperature sensors. As a result, resistance change per unit degree is more efficient than commercially available sensors.
- SPACE SATELLITE MODULE
Space-Satellite module is a special module containing specially designed NürFETs to investigate space radiation. The sensor has a microscopically small sensor volume, which opens up opportunities for radical new designs of the miniature radiation detection system. Compared to other detector systems, the NürFET system is compact and easily combined with computer power. This module can be used in space applications. It is integrated with the domestic satellites TÜRKSAT 6A, IMECE, and APSCO LEO. The value of the imported module for satellite applications is approximately 400,000 Euros. However, the cost of the Space-Satellite Module produced is approximately 50,000 TL.
- BIOSENSORS (GFETS)
GFETs are one of the special types of MOSFETs. The main difference between GFETs is the active area. The gate area is covered with Graphene or Graphene derivatives. Graphite is converted into Graphene, Graphene oxide, and reduced Graphene oxide through chemical reactions. These structures are then coated by the active area of the FET. The most extensive use of GFETs is as biosensors or chemical sensors. The main application of GFETs is produced for biosensors. Biosensors will be used in the detection of early diagnosis of “Lung” and “Lymphoma” cancers and cancer metastases and will provide early diagnosis and early treatment. The detection time of the biosensors will be approximately 2 minutes.
