A Novel Fabrication Technique For Three-Dimensional Nanostructures, Ravi Kiran Bonam Jan 2012

A Novel Fabrication Technique For Three-Dimensional Nanostructures, Ravi Kiran Bonam

Legacy Theses & Dissertations (2009 - 2024)

Three dimensional micro- and nano-structures are commonly used in the field of Photonics, Optoelectronics, Sensors and Biological applications. Although numerous physical models are developed, a major challenge has been in their fabrication which is commonly limited to conventional layer-by-layer techniques. In this dissertation, a novel method for fabricating three dimensional structures using Electron Beam Lithography (EBL) will be presented.


Evaluation Of Chemical Mechanical Planarization (Cmp) For The Removal Of Surface Defects In Extreme Ultraviolet Lithography (Euvl) Mask Substrates, Bradley Halligan Wood Jan 2012

Evaluation Of Chemical Mechanical Planarization (Cmp) For The Removal Of Surface Defects In Extreme Ultraviolet Lithography (Euvl) Mask Substrates, Bradley Halligan Wood

Legacy Theses & Dissertations (2009 - 2024)

A modified CMP process was investigated and developed with the goal of removing surface defects (nanoscale depressions or `pits') from quartz mask blank substrates. Initially, quartz glass wafers were evaluated to observe surface roughness and defect introduction due to low down-force CMP processing. Following analysis of quartz glass wafers subjected to such processing it was determined that a CMP-based processing for pit removal of maskblank substrates was potentially viable. Consequently, a specially-designed mask carrier for investigating and developing CMP-based defect removal from EUV maskblank substrates was mounted on a Strasbaugh 6DS-SP CMP laboratory tool. A series of experiments was performed …
