The working electrode (sensing) was fabricated by depositing gold on Teflon electrodes. The auxiliary (counter) and the reference electrodes were defined on Al2O3 using platinum serigraphic paste. The platinum screen-printed electrodes were chemically modified by dipping in 1HF(49%):10H2O solution (d-HF) for times ranging from 10 to 120 min to obtain a three-electrodes potentiostatic cell for acetylene detection. Cyclic voltammetry indicated voltage-separation decreasing of the redox peaks and peak-current increasing when time in d-HF was increased. Surface morphology has changed after dipping in d-HF. It was noteworthy that valley-to-peak height and valley area increased, which meant better performance of the auxiliary and reference electrodes. As a result, a stable electrochemical sensor was fabricated with a detection limit of 500 ppm for acetylene dissolved in argon.","PeriodicalId":113603,"journal":{"name":"2016 31st Symposium on Microelectronics Technology and Devices (SBMicro)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131177116","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}

To better evaluate the applicability of this material, we measured the elastic modulus of Protek-PSB coatings using the beam bending method with cantilevered beams of Protek-PSB.

The results were obtained through experimental measurements in a device with channel length (L) of 240 nm, working in linear regime at VDS=50mV. It is shown that the origin of the noise changes from carrier number fluctuations to mobility fluctuations as the temperature is increased. Additionally, the generation and recombination noise plays a significant role on the overall noise with the temperature rise.","PeriodicalId":113603,"journal":{"name":"2016 31st Symposium on Microelectronics Technology and Devices (SBMicro)","volume":"6 26","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120855014","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 pseudo-resistor presents two different behavior regions, and as described in this work, in bio-amplifiers applications, important functions are assigned to each of these regions. 0.13 μm 8HP technology from GlobalFoundries was chosen as the target technology for the prototypes, because of its versatility. Due to the very-low current of pseudo-resistors, a circuit for indirect resistance measurement was proposed and applied. The fabricated devices presented resistances over 1 teraohm and preserved both the linear and the exponential operation regions, proving that they are well suited for bio-amplifier applications.","PeriodicalId":113603,"journal":{"name":"2016 31st Symposium on Microelectronics Technology and Devices (SBMicro)","volume":"24 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113942830","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}
