A WAFER LEVEL VACUUM PACKAGING TECHNOLOGY FOR MEMS BASED LONG-WAVE INFRARED SENSORS
Demirhan Aydın, Gülşah; Akın, Tayfun; Kalay, Yunus Eren; Department of Micro and Nanotechnology (2022-8-11)
This thesis proposes a new approach to obtain a wafer level vacuum packaging that satisfies the requirements of the thermal sensors at low cost and with high performance. The moth-eye structures are formed on both side of a polished flat silicon wafer without any cavity to allow the transmission of the infrared radiation in long wave infrared region (LWIR). Then, this wafer is bonded to another spacer wafer using Au-In Trans-liquid phase (TLP) approach that allows bonding at low temperature (around 200℃); t...
A fabrication process based on structural layer formation using Au-Au thermocompression bonding for RF MEMS capacitive switches and their performance
Cetintepe, Cagri; Topalli, Ebru Sagiroglu; Demir, Şimşek; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2014-10-01)
This paper presents a radio frequency micro-electro-mechanical-systems (RF MEMS) fabrication process based on a stacked structural layer and Au-Au thermocompression bonding, and reports on the performance of a sample RF MEMS switch design implemented with this process. The structural layer consists of 0.1 mu m SiO2/0.2 mu m SixNy/1 mu m Cr-Au layers with a tensile stress less than 50 MPa deposited on a silicon handle wafer. The stacked layer is bonded to a base wafer where the transmission lines and the iso...
A fabrication-oriented remeshing method for auxetic pattern extraction
Mert, Levend Mehmet; Yaman, Ulaş; Sahillioğlu, Yusuf (The Scientific and Technological Research Council of Turkey, 2020-01-01)
We propose a method for extracting auxetic patterns from meshes for fabrication by modifying the existing mesh primitives directly and fully automatically. This direct approach is novel in the sense that most of the fabrication-oriented surface tiling methods introduce additional primitives, such as curve networks in an interactive semiautomatic framework. Our method is based on a remeshing procedure that converts a given quad mesh with arbitrary topology into our desired structure that is ready to be fabri...
A readout circuit for QWIP infrared detector arrays using current mirroring integration
Tepegoz, M; Akın, Tayfun (2003-09-18)
This paper reports a current mirroring integration (CMI) CMOS readout circuit for high-resolution Quantum Well Infrared Photodetectors (QWIPs). The circuit uses a feedback structure with current mirrors to provide stable bias voltage across the photodetectors, which can be adjusted between 0 V and 3.5V. The photodetector current is mirrored to an integration capacitor which can be placed outside of the unit pixel, reducing the pixel area and allowing to integrate the current on larger capacitances for large...
A DC Bus Capacitor Design Method for Various Inverter Applications
Hava, Ahmet Masum; Aban, Vahap Volkan (2012-09-20)
This paper involves the selection and sizing of the appropriate type of dc bus capacitor for various applications utilizing PWM operated three-phase voltage source inverters, such as battery operated systems, PV (photovoltaic) systems, UPSs, and motor drives. It classifies the power converter topologies based on dc bus ripple current frequency characteristics. A general approach for ripple current characterization is provided. Based on these characteristics, the two capacitor types suitable for this purpose...
