Heterogeneous integration was recognized as being the key vehicle to continue miniaturization. However, it requires the combination and close packing of vastly different materials like low CTE semiconductors (Si, SiC, GaN, etc.) with high CTE heat dissipation materials (Cu/Al) to prevent overheating. The very different mechanical properties have led to warpage, delamination and early failures and have become the limiting factors in yield and reliability. Therefore, heat dissipation and CTE have become the roadblocks to technological advancement in packaging: we need new materials with matching properties not currently available. Solutions were attempted in the past with WCu and AlSiC macro-composites with limited success. Issues like high density, limited CTE tailoring, challenging high temperature manufacture and lack of solderability prevented their widespread use. In an effort to solve this problem, we used nanotechnology to design materials with new properties that are not available in nature. We used our copper-based nanomaterial to create a materials system that allows precise CTE-tuning between 3–17 ppm while retaining the highest possible thermal conductivity. The ready flowability of the formulated paste precursor drastically improves processability at low temperatures (200–240 °C) in minutes allowing the use of a rapid injection molding process, enabling low-cost mass-production of near-net-shape parts. Importantly, it can be soldered to directly without additional metallization. This ActiveCopper (aCu) materials system can replace the copper coin technology and readily manufacture CTE-matched lead-frames, heat sinks/spreaders and heat pipes for maximum heat dissipation.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"64 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85751515","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 devices find application in health and environmental sciences for the detection of biomolecules. One long-standing detection principle is resistive pulse sensing (RPS) which has been adapted to the sub-micrometer scale. The key element in RPS is the nanopore by which the electric current is monitored. Pulses in the electric current are formed upon the translocation of particles through the nanopore. Different technologies can be used to create these nanopores, but the material and the aspect ratio impose limitations. In this study, the focused ion beam technology was used to create a high-aspect-ratio nanopore in a multi-layer-duo-material membrane. We used the data to develop a new 2D numerical model to study the pore geometry and investigate irregularities in its shape. Impedance frequency analysis results show the sensitivity of this method to differentiate among high similar geometries.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"36 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80204930","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}

ECs are proved to be highly beneficial in different energy storage systems such as smart grids. To increase ECs energy density, pseudocapacitive materials (i.e., transition metals) that take advantage of fast and reversible surface Faradaic reactions for the accommodation of charges are utilized. Among various transition metal compounds, RuO2 exhibits a very high capacitance. However, transition metal nitrides (e.g., VN) have attracted much attention due to their promising mechanical properties and high electrical conductivity when compared to their oxide counterparts. Here, we first grow multi-walled carbon nanotubes (MWCNTs) with a forest-like structure on a stainless-steel 316L mesh by chemical vapor deposition. MWCNTs are used as a support material with high electrical conductivity, high specific surface area, and high electrochemical stability that exhibit an electrochemical double layer capacitance. Then, RuNx thin coatings are deposited by radio frequency plasma-assisted pulsed laser deposition (PAPLD) and atomic layer deposition (ALD) techniques. The results of X-ray photoelectron spectroscopy confirm a successful deposition of RuNx on the silicon substrate. The capacitance of the electrodes is calculated in in 1M KOH electrolyte and a high capacitance of 728 F g−1 is achieved.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"86 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87685997","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}
