Course content

3 sections • 20 lectures • 3h 11m total length

  • Introduction5:02

    Explore nanofabrication techniques like e-beam lithography, physical vapor deposition, chemical vapor deposition, and molecular beam epitaxy to create 2D thin films, nanowires, quantum dots, quantum wells, and heterostructures.

  • Too many nano stuffs15:27

    Explore the reality of nano branding and the R&D-to-market flow, focusing on metals, semiconductors, and 0D–3D nanostructures for practical devices.

  • Basics of Crystal7:38

    Learn how a four-atom unit cell can be rotated and repeated to form a crystal layer, and why its properties define the material. Distinguish crystalline from amorphous patterns.

  • CZ method of Crystal Growth4:23

    Explore the Swarovski method for bulk silicon crystal growth: seed in molten silicon with rotation, inert gas, graphite crucibles, RF heating, and a steady 1 mm/hour pull.

  • Floating Zone method of Crystal Growth3:48

    Melt silicon to form a molten zone between a solid feedstock and seed in argon, enabling floating zone crystal growth and producing large, pure crystals.

  • Wet Etching6:06

    Learn the wet etching process in nanofabrication, using diluted acids to remove silicon dioxide, with safety training, rinsing, and dry nitrogen drying, noting its isotropic behavior.

  • Dry Etching7:40

    Dry etching uses gas-phase processes to achieve anisotropic, vertical etching for nanoscale devices, with plasma or ion sources and customizable chambers.

  • For Startups and Investors: An example of setting up an etching project9:58

    learn how startups and investors set up an etching project, balancing equipment, manpower, and chemical costs for wet and dry etching on silicon or gallium arsenide, with in-house tool ideas.

Description

  • In this program, we comprehensively explore the primary nanofabrication methodologies. We commence with an overview of nanotechnology and progress to bulk crystal growth. Subsequently, we delve into both dry and wet etching techniques. Following this, we dedicate an entire section to various lithography methods, with a particular emphasis on the construction and operational strategies of these instruments. Our exploration extends to deposition techniques, encompassing both physical and chemical vapor deposition methods in thorough detail.

  • Each section includes practical projects or investor-focused mind maps, enabling analysis of key parameters relevant to product development and market viability. Throughout, we employ a variety of illustrative tools such as diagrams, mind maps, process diagrams, and even 3D animations when necessary.

  • This course caters to a diverse audience. Whether you're a bachelor's, master's, or PhD student, the concepts are presented in an easily digestible manner. Likewise, entrepreneurs and investors will gain insights into the strategic and economic considerations surrounding these tools and techniques, facilitating informed investment decisions. If you are a professor or a lecturer teaching in a university or engineering college, it will help wrap up the different tools and maneuver them.
