A desirable goal of engineering education is to teach students how to be creative and innovative. However, the speed of technological innovation and the continual expansion of disciplinary knowledge leave little time in the curriculum for students to formally study innovation. At West Point we have developed a novel upper-division undergraduate course that develops the critical thinking, creativity and innovation of undergraduate science and engineering students. This course is structured as a deliberate interactive engagement between students and faculty that employs the Socratic method to develop an understanding of disruptive and innovative technologies and a historical context of how social, cultural, and religious factors impact the acceptance or rejection of technological innovation. The course begins by developing the background understanding of what disruptive technology is and a historical context about successes and failures of social, cultural, and religious acceptance of technological innovation. To develop this framework, students read The Innovator’s Dilemma by Clayton M. Christensen, The Structure of Scientific Revolutions by Thomas S. Kuhn, The Discoverers by Daniel J. Boorstin, and The Two Cultures by C.P. Snow. For each class meeting, students survey current scientific and technical literature and come prepared to discuss current events related to technological innovation. Each student researches potential disruptive technologies and prepares a compelling argument of why the specific technologies are disruptive so they can defend their choice and rationale. During course meetings students discuss the readings and specific technologies found during their independent research. As part of this research, each student has the opportunity to interview forward thinking technology leaders in their respective fields of interest. In this paper we will describe the course and highlight the results from teaching this course over the past five years.

High-contrast process using a positive-tone resist with antistatic coating and high-energy (100-keV) e-beam lithography for fabricating diffractive optical elements (DOE) on quartz

Louis Poli, Christine Kondek, Barry Shoop, George McLane

Diffractive optical elements (DOE) are becoming important as optical signal processing elements in increasingly diverse applications. These elements, fabricated on quartz, may be used as phase shift type masks or as embedded components that implement a transfer function within a processing network. A process is under development for the fabrication of a DOE implementing a Jervis error diffusion kernel for research in half tone image processing. Dry etching is performed after lithography and pattern transfer through a nickel mask. This results in etched areal features on the substrate. An optical diffraction medium is thus created. Lithographic patterning is done by e-beam lithography (EBL) to realize small features, but also offers the important advantage of a large depth of field which relaxes the problem of complex surface topology. The recent availability of high energy (100 KeV) lithography tools provides a capability for precision overlay, small feature resolution, and enhanced image contrast through a lower induced proximity effect. Patterning by EBL on insulating substrates is complicated by the necessity of providing a vehicle for the avoidance of charge buildup on the surface. In a previously presented paper a methodology was shown for the use of TQV-501 (Nitto Chemical) antistatic compound as a final spin on film for use with PMMA and SAL-601 (Shipley). In this current work, a process is described using EBL and a high performance positive resist working with a final film layer of antistatic TQV-501 on a nickel coated wafer. The process may then be reapplied to realize additional lithographic levels in registration, for multilevel DOE components. High energy (100 KeV) EBL is used to provide high quality pattern definition. The e-beam sensitive resist, ZEP-320-37 (Nagase Chemical) in dilution, together with a top film layer of TQV-501 serves as a bilevel resist system and is used for patterning the desired image before definition of the nickel mask through a wet etch. ZEP- 320-37 in 1:1 dilution with the native solvent is spin applied and softbaked for 2 hours at 120 degree(s)C, after which the antistatic film is spin applied and softbaked for 10 minutes at 70 degree(s)C. After exposure, the TQV film is removed within the development procedure itself. The image is developed in xylene followed by a thorough IPA rinse. The pattern is then transferred to the nickel film via a dilute HCl etch bath. Finally, magnetron RIE is performed on the substrate through the defined nickel mask, after which the nickel film is completely removed in HCl.2438
