We fabricated micro pillars and formed 60 nm thick CYTOP layer around its side walls and to the surface of silicon substrate. By forming the CYTOP layer around micro pillars, we demonstrated that the numbers of the protruded cells to the gaps around the pillar became a half compared to those without CYTOP.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124893733","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}

Colloidal lithography, also known as nanosphere lithography (NSL), has been extensively and exhaustively utilized to create various nanostructures with the limitation in the resulting morphology and array spacing. Especially, independent control over the individual nanostructure size and array pitch remains a challenge and is the subject of this paper. Here, we show three different methods that expand the type of the nanostructure array produced from NSL. First, the combined technique of NSL and metal-assisted chemical etching (MACE) is shown to generate vertically-aligned Si nanowire (SiNW) array with the unprecedented dimensional control. Second, a stretchable elastomer with transfer printing is utilized to control the pitch of the original NS arrays, and with a custom-designed radial stretcher, a hexagonal symmetry of the resulting nanostructures is conserved. An array of sparsely ordered silicon or quartz nanopillars is obtained along with metallic nanostructures on NSs as etch masks. Finally, a double lift-off method is introduced to create an array of metallic nanodots that are not conventionally realized using the NSL template.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121410006","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}

Removal of the Mo layer after graphene deposition results in a transfer-free and controlled placement of the graphene on the underlying SiO2. Moreover, pre-patterning the Mo layer allows customizable graphene geometries to be directly obtained, something that has never been achieved before. This process is extremely suitable for the large-scale fabrication of MEMS/NEMS sensors, especially those benefitting from specific properties of graphene, such as gas sensing.","PeriodicalId":157312,"journal":{"name":"2016 IEEE 29th International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125804385","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}
