A novel complementary metal oxide semiconductor (CMOS) compatible microchannel heat sink is designed and fabricated for monolithic liquid cooling of electronic circuits. The microchannels are fabricated with full metal walls between adjacent channels with a polymer top layer for easy sealing and optical visibility of the channels. The use of polymer also provides flexibility in adjusting the width of the channels allowing better management of the pressure drop. The proposed microchannel heat sink requires no design change of the electronic circuitry underneath, hence, can be produced by adding a few more steps to the standard CMOS fabrication flow. The rnicrochannel heat sinks were tested successfully under various heat flux and coolant flow rate conditions. The preliminary cooling tests indicate that the proposed design is promising as a monolithic liquid cooling solution for CMOS circuits.

Design, fabrication, and experimental evaluation of microchannel heat sinks in cpu cooling Koyuncuoğlu, Aziz; Okutucu Özyurt, Hanife Tuba; Arınç, Faruk; Department of Mechanical Engineering (2010) A novel complementary metal oxide semiconductor (CMOS) compatible microchannel heat sink is designed, fabricated, and tested for electronic cooling applications. The proposed microchannel heat sink requires no design change of the electronic circuitry underneath. Therefore, microchannels can be fabricated on top of the finished CMOS wafers by just adding a few more steps to the fabrication flow. Combining polymer (parylene C) and metal (copper) structures, a high performance microchannel heat sink can be ea...
A Low-power capacitive integrated CMOS readout circuitry for high performance MEMS accelerometers İncedere, Osman Samet; Akın, Tayfun; Eminoğlu, Selim; Department of Electrical and Electronics Engineering (2013) This thesis presents a low power capacitive integrated CMOS readout circuitry for high performance MEMS accelerometers. It proposes a linearized model of the complete closed loop accelerometer system, which makes easier of designing and analyzing the system. Designed readout circuitry offers low noise, wide dynamic range and high linearity system with very low power consumption. Designed readout circuit includes proportional integral (PI) controller circuit, which significantly decreases the proof mass defl...
Application of Electric Resistance Heating Method on Titanium Hot Forming at Industrial Scale Ozturk, Fahrettin; Ece, Remzi Ecmel; Polat, Naki; Koksal, Arif; Evis, Zafer; Sheikh-Ahmad, Jamal Y. (Springer Science and Business Media LLC, 2016-11-01) In this study, hot forming of DIN WL 3.7024 commercially pure titanium with a sheet thickness of 0.6 mm was performed by electric resistance heating. The sheet materials were heated at 600, 650, and 680 A degrees C and then hot formed with an industrial press. Grain size measurement and XRD analysis were performed for each forming temperature in order to investigate microstructure and phase changes. Results indicate that no microstructural changes have occurred at the mentioned temperature range. It was con...
Improvement of light emission from Tb-doped Si-based MOS-LED using excess Si in the oxide layer Kulakci, Mustafa; Turan, Raşit (2013-05-01) The fabrication of efficient silicon-based Light Emitting Devices (LEDs) is extremely important for the integration of photonic and electronic components on the same Si platform. In this paper, we report on the room temperature electroluminescence properties of Tb-doped MOS-LED devices with an active layer of SiO2 and Si-rich SiOx produced using the magnetron co-sputtering technique. The electroluminescence properties of both types of devices were studied as a function of processing conditions and material ...
A Thermal and Electro-magnetic Hybrid MOEMS Microscanner with Integrated Spatial Light Modulation and Metalens for Resolution Enhancement of Infrared Imaging Systems Sozak, Ahmet; Simsek, Ertug; Yelboga, Tolga; Gungor, Alper; Balli, Fatih; Azgın, Kıvanç (2022-01-01) IEEEThis article describes the development of a novel integrated thermal and electro-magnetic hybrid micro opto-electro mechanical system (MOEMS) based scanning actuator. Determining the optical architecture and components used for scanning are significant points of the study. A metalens and a coded mask, both of which can be produced by micro fabrication methods, are used in the optical part of the actuator. In this context, a metalens consisting of nano-holes was designed and fabricated as the first alter...
