In this work, photocurable method was used to develop sensing membrane for Potassium ChemFET (K ChemFET) sensor.

Thermal converts temperature differences directly into electrical energy. While vibration is based on human movement like walking and shaking body that is able to generate an AC voltage. Having two sources overcome the limitation caused by a single source harvester and improves system functionality. The inputs are set to 0.2V, 0.3V and 0.5V to represent thermal, vibration and combination of thermal and vibration (hybrid) respectively. A rectifier is designed to convert vibration input from AC to DC voltages. The proposed boost converter is used to step-up the small input voltage from thermal and vibration at 2 kHz. The inductance is varied from 0.4μH to 1.2μH, 0.9μH to 2.9μH and 0.3μH to 0.9μH for vibration, thermal and hybrid input respectively. However, the optimize value for the designed is 0.9μH for all sources to achieve the regulated output of 2.0 to 4.0V. Both rectifier and boost converter circuit consist of MOSFET as the heart of the operation.

An overview of the simulated fabrication process and the performance of the three promising candidates for succession of the conventional vertical Impact Ionization MOSFET (IMOS): Single Channel vertical strained impact ionization MOSFET (SC-VESIMOS) [13], Dual Channel vertical strained impact ionization MOSFET (DC-VESIMOS) [14] and vertical strained impact ionization MOSFET incorporating Dielectric Pocket (VESIMOS-DP) is investigated using Silvaco package. These three devices offer possibilities to overcome physical limits occurring during the continuous shrinking process like the limitation of the subthreshold swing S to 60 mV/dec at room temperature or rising leakage currents due to tunneling. The performance of these novel devices can be extremely promising for applications where ultra-high sensitivity and fast response is desirable. An ultra-low power with low Subthreshold Swing and high breakdown voltage are imperative for ultra-sensitive biosensor. Eventually, these devices will prolong the increase density of transistor on a chip for future application of biosensor nanoelectronics.","PeriodicalId":6667,"journal":{"name":"2015 IEEE Regional Symposium on Micro and Nanoelectronics (RSM)","volume":"18 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75580403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this project, the focus will be on fabrication and characterization of the IDTs parameter of the SAW device using conventional photolithography and lift-off technique. Finger width, acoustic aperture and number of IDT finger pairs were varied to analyze its effect on the resistance, coupling capacitance, and frequency response. After the lift-off technique, the completed SAW devices were characterized with respect to its parameter for its current-voltage, capacitance-voltage and frequency response.

Initial finding show the correlation with the big size poly PIP capacitor structure. Therefore, the challenge was to focus on big size PIP structure. But during partition check, we found the weakness of the photoresist stripping during O2 plasma ashing. The weakness show not only big size pattern but also small size area. Through EDX analysis, we found Si byproduct block oxygen reaction with photoresist. As a consequence, following sulfuric clean has no margin to remove all photoresist which cause photoresist residue on big size of pattern. Several approaches were carried out to identify the optimal solution for defect removal. And, it was found that the additional sulfuric clean without HF is best solution. The photoresist residue defect was then eliminated completely with the new cleaning condition.","PeriodicalId":6667,"journal":{"name":"2015 IEEE Regional Symposium on Micro and Nanoelectronics (RSM)","volume":"184 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77305936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These bonding techniques require high temperature which results in bending/buckling of MEMS devices especially in case of hanging structures. In this work, low temperature and low cost bonding techniques with commercially available epoxy 320 NC and photoresist SU-8 2010 are done. Bonding with commercially available epoxy 320 NC at room temperature leads to spreading of epoxy in device region and affects the device performance. To define bonding ring dimensions, photoresist SU 8 2010 is used as an adhesive. Sharp dimensions of SU 8 2010 bonding ring are achieved using lithography. Top silicon cap is fabricated using TMAH etching. The bonds made with these techniques gave good shear strength, as measured with an indigenous setup.","PeriodicalId":6667,"journal":{"name":"2015 IEEE Regional Symposium on Micro and Nanoelectronics (RSM)","volume":"87 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76159409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrode configuration is such that the top and bottom surfaces support multiple finite sized electrodes in the range of few micrometers. The electric potential inside the microchannel takes the form of Laplace equation while the equations of motion are based on Newton's second law. The forces considered include that due to inertia, drag, gravity, buoyancy and dielectrophoresis. All governing equations are solved using finite difference method with a spatial step size of 0.5 μm and temporal step size of 10-4s. In addition, a parametric study is carried out in order to understand the individual influence of operating and geometric parameters on the path of microparticles. The parameters considered include microparticle radius, actuation voltage, volumetric flow rate and microchannel height. It is found that all parameters influence the transient trajectory of microparticles while only a few parameters influence the final levitation height of microparticles.","PeriodicalId":6667,"journal":{"name":"2015 IEEE Regional Symposium on Micro and Nanoelectronics (RSM)","volume":"11 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91108025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
