Course Descriptions

1A. Overview of Focused Ion Beam Techniques – Dr. Keana Scott, NIST

Abstract

Focused Ion Beam (FIB) instruments have been around for more than twenty years now and widely used in the semiconductor industry and materials science research.  However, the recent availability of dual platform (focused ion beam and scanning electron beam) instruments and the advances in the control and processing software for these instruments have led to a widespread adoption of FIB technology in many new application areas.  A brief overview of the FIB and FIB SEM technology, instrumentation and applications will be presented, including some discussions on the capabilities and limitations of the FIB and FIB SEM techniques in general, brief descriptions of current commercially available tools and several FIB application examples.

1B. Bottom-up Nanofabrication – Dr. Jason Benkoski, JHU/APL

Abstract

Self-assembly is the spontaneous organization of small building blocks into complex structures where the blueprint for the final structure is embedded within the design of the building blocks themselves. Self-assembly is technologically important because of its ability to create nanostructured materials that would not otherwise be possible to make using “top-down” photolithography methods or similar conventional techniques. Self-assembled structures are characterized by excellent short-range order, poor long-range order, hierarchical organization over multiple length scales, and fractal morphologies. Not coincidentally, these structures resemble natural materials like bone and wood, since biological materials are also made by self-assembly. In this seminar we will explore a number of examples illustrating the relevance of this technology for those new to the subject. It will provide a quick primer on the key concepts needed to appreciate how the process works, and when it is most beneficial to use “bottom-up” self-assembly in the context of conventional, semiconductor microfabrication and similar “top-down” technologies.

Bio

Dr. Benkoski received his Ph.D. in 2003 under the supervision of Prof. Ed Kramer, where he studied “The Molecular Mechanisms of Polymer Fracture.”  Shortly thereafter he received a fellowship from the NSF to develop a platform for light-regulated, reusable protein sensors. In 2005 received a National Research Council Fellowship to develop novel processing routes for creating hierarchical biomimetic topologies via self-assembly at photocrosslinkable oil/water interfaces.  He now serves as a Senior Scientist in the Milton S. Eisenhower Research Center at JHU/APL where he heads a research program devoted to the development of nanoscale mechanical actuators built from the self-assembly of Co nanoparticles. He also leads a program funded by ONR to develop Polyfibroblast, a self-healing paint that provides galvanic protection.  His interests include self-assembly, biomimetic materials, and stimulus-response materials.

1C. State-of-the-Art in Rapid Prototyping Technologies – Dr. Mike Rooney, JHU/APL

Abstract

Rapid Prototype technologies, also known as 3D Printing or Manufacturing, has been around for 20+ years now, but the number of technologies and materials has exploded in the just the last few.  A review of the current state-of-the-art in polymer, metal and ceramic RP technologies will be presented.  While a comprehensive list of system manufacturers and materials will be presented and some discussed in detail, the list grows nearly daily (particularly for materials).  The technologies are at the point where custom materials are becoming the norm, which is where the evolution for micro and nano-particle enhancements has already begun.

Bio

Dr. Michael Rooney is a Materials Researcher with over 25 years experience in characterizing and applying a broad range of materials and their associated fabrication processes.  With a Masters and PhD in Materials Science & Engineering from Johns Hopkins University, he has worked at the JHU Applied Physics Laboratory (APL) for the last 15 years as the Supervisor of the Applied Materials/Materials Engineering Section.

Mr. Robert Matteson and Mr. Paul Biermann, Materials & Process Engineers in the Composites/Polymers Fabrication area, also plan to help present the options, opportunities and future of the various processes to be discussed.

2A and 3A. Hands-on Flip-Chip Bonding – Vindhya Reddy and Andrea Pais, SB Microsystems

Abstract
“Flip-Chip Bonding”, also called “Direct Chip Attach” is one of the methods of interconnecting devices.  Typically, electrical connection of face-down (flipped) electronic components onto carriers or circuit boards are made by means of conductive bumps on the chip bond-pads.
This short course on flip chip bonding will comprise of two sessions. During the first session held at JHU, we will describe what flip chip bonding is, its applications in various fields and how it compares to other types of bonding. The course will mainly focus on its wide range of applications in the industry, including some examples from our own experience. During the second session, we will hold a hands-on demo at our SB Microsystems office in Columbia, MD.

At SB Microsystems, their work mainly consists of creating process development and packaging solutions for customers.  Andrea leads the process engineering team and their interest is not just in building circuits but in miniaturizing complete systems onto silicon: be it fluidic or mechanical components, sensors, circuits- anything you can imagine.

2B. Ethical Influence: How to Get What you Want – Dr. Mark Happel, JHU/APL

2C. Electrochemical Actuators for BioMEMS – Prof. Elisabeth Smela, University of Maryland

Abstract

This short course will provide an overview of electrochemical actuator technology, including the motivation and challenges, applications, and actuation mechanism. The course will focus on conjugated polymer actuators, which have been fully integrated into standard microfabrication processes. We will begin with a brief introduction to electrochemistry and the conjugated polymer materials that are used. The applications that will be covered include cell manipulation, microfluidic valving, neural probe steering, and drug delivery. Methods for depositing and patterning the materials will be presented, followed by how they are actuated. Finally, their performance metrics will be reviewed.

3B. Overview of Graphene Properties and Processing – Dr. Janice Guikema, Johns Hopkins University

Abstract

Graphene is often described as a new “wonder” material.  Its serendipitous discovery in 2004 (for which Geim & Novoselov were awarded the 2010 Nobel prize) has ignited intense interest ranging from fundamental science to applied technology.  The thinnest material in the world, graphene is a two-dimensional sheet of carbon atoms only one atom thick. This elegantly simple material has exceptional electronic, optical, thermal and mechanical properties.  In this course I will introduce graphene’s properties and a number of promising applications such as flexible transparent electrodes, next-generation transistors, energy applications and sensors.  I will also discuss the primary methods for large-scale production of graphene, as well as current challenges and limitations in making and using graphene.

3C. Process Flow Design for Top-Down Nanofabrication – Mr. Vincent Luciani, NIST

Abstract

Successful top-down nanofabrication requires not only a good idea, but also attention to device design, process limitations, and the sequence of processing steps. First pass success in fabricating prototypes is an important measure of success in research or the fast paced world of product development and the preparation and documentation of your process plan will determine your chances for success. In this class, we will discuss how to design a process – including deposition, lithography, etching and chemical cleans- that will maximize device success and yield. The discussion will be in the context of NIST’s Center for Nanoscale Science and Technology NanoFab facility, a user facility available to academic, industrial, and government researchers. The CNST has extensive capabilities, including electron beam lithography, focused ion beam, nano-imprint and laser lithography.
