STM Tip Fabrication Process Development

Associated with Rose-Hulman Institute of Technology
August 2025 - Now




This is my Senior Design Project for Rose-Hulman Institute of Technology. My group's client was NeXus at the Ohio State University. They tasked us with developing a process for fabricating Tungsten tips for their Scanning Tunneling Microscope (STM).

MiNDS Lab Wiki

Associated with Rose-Hulman Institute of Technology
August 2025 - Now




This is an internally hosted Wiki for the Micro and Nano Devices and Systems (MiNDS) class 1000 clean room at Rose-Hulman Institute of Technology.

The purpose of this wiki was to centralize information about the tool capabilities of our clean room for professors building course materials, students doing labs, and researchers developing nanofabrication processes. This page is currently in the "beta testing" stage of development. I am surveying clean room users (students, professors, technichians) for feedback about ease of navigation and what materials they would like to be included in the page.

The website was initially built on the open-source Wiki software Zim for CSS formatting. I then adapted the HTML and CSS code in NeoCities to make the page more mobile-friendly and easy to navigate. It was important this page would be compatible with iPads, as we primarily use tablets for collecting data in the clean room.

This wiki is entirely comprised of open-source materials that can be adapted into course materials and lab reports. The page is maintained under CC0 licensing for this purpose. Additionally, the entire page (text, code, diagrams) was developed without the use of LLMs or AI.

  • Cool Thing Project Winner: IBM 5155 PC Model

    Associated with Rose-Hulman Institute of Technology
    October 2025 - November 2025




    This is a SOLIDWORKS model of an IBM 5155 from 1984. It is a 1:1 model that was based off an actual IBM portable PC.

    My Senior year at Rose-Hulman Institute of Technology, I took an introductory Graphical Communications course (EM104). The final project for this course was the "Cool Thing Project", where students in each class section competed to create the "coolest" SOLIDWORKS model. Students voted on their favorites at the end of the course. The winning models are 3D printed and displayed for the year by the Department of Mechanical Engineering.

    High-Quality Silicon Oxide Film Development for Boron-Doped Diamond Devices

    Associated with Michigan State University, Fraunhofer USA Inc. CMW
    June 2025 - August 2025




    This 10-week project was done through the Early Engagement in Semiconductor Materials and Technology Undergraduate research opportunity (EESMT REU) at Michigan State University. I worked with Dr. James Siegnethaler in the Fraunhofer USA Inc. CMW office in East Lansing, Michigan.

    Boron doped diamond (BDD) is a versatile material that is chemically stable and well-suited for electrochemical measurements such as heavy metal measurement in water. When submerged, electrodes with this material must be encased with a defect-free insulating layer to ensure a defined sensing area. Silicon oxide is a cheap and effective material for this task. I optimized a high-quality SiO2 thin film recipe for plasma-enhanced chemical vapor deposition (PECVD) and idenfided some system-level issues that were affecting the quality of the tool's depositied films.

    I presented this project at Michigan State University for MidSURE 2025 and for the ID4 Symposium at Northwestern Univeristy later that summer.

  • Low-Resistivity Titanium Nitride Thin Films

    Associated with Rose-Hulman Insitute of Technology
    June 2024 - September 2024




    This 10-week project was done with Dr. Daniel Marincel at Rose-Hulman Institute of Technology. It was one component of a larger project developing a CMOS memory device system using a ferrorelectric electrode. My goal was to develop low-resisitivity TiN thin films using DC magnetron sputtering.

    Titanium Nitride (TiN) is a ceramic material with metallic properties and unique application in diffusion barriers for electrodes. By controlling the resistivity of these films, we can create asymmetrical electrodes ideal for FET memory devices. I affected the resistivity of these films using the magnetron power, nitrogen gas concentration, and total gas flow during the deposition of these films.

    I presented a poster about this project at Rose-Hulman for Homecoming 2024 and for department alumni later that year.

  • Heat Actuator Fabrication

    Associated with Rose-Hulman Insitute of Technology
    March 2024 - May 2024




    This was a laboratory project for one of my Nanoengineering undergraduate courses, Introduction to MEMS (MDS 437, previously NE 410). I worked in a group of three students.

    Curly Carbon Nanotubes

    March 2023 - May 2023




    This was a laboratory project for one of my Nanoengineering undergraduate courses, Nanotechnology, Entrepreneurship & Ethics (NE 380). I worked in a group of three students.

    Diffraction Grating Fabrication

    February 2023 - March 2023




    This was a laboratory project for one of my Nanoengineering undergraduate courses, Introduction to Nanoengineering (NE 280). I was in a lab group of two students.

    MEMS Keychain Project

    Associated with Rose-Hulman Insitute of Technology
    March 2023 - May 2023




    This was my first fabrication project in a clean room, and a lab for the course Introduction to Nanoengineering (NE 180). I later TA'd the class and supervised these laboratory sessions, and developed materials for the lab for a Summer course as well. We used an oxidation furnace to created colored wafers, then used a general MEMS mask to create aluminum shapes. We then diced the wafers and encased them in keychains as a keepsake. The design was purely aesthetic, and intended to be an introduction to sputtering and photolithography rather than a usable device.

    The Singing Revolution: Russian-Language Presentation

    Associated with American Councils and U.S. Department of State
    May 2022 - August 2022




    The National Security Language Intiative for Youth program (NSLI-Y) associated with the U.S. Department of State offers summer, year-long, and virtual defense language programs. I was awarded the Summer Russian Language scholarship, and studied Russian in Narva, Estonia for eight weeks. I stayed with a Russian-speaking host family and attended 200+ language classes at University of Tartu's Narva College.

    My final project for this program was to create a ten-minute presentation about a topic of my choice. I selected the Singing Revolution and the history of the Baltic Way as my presentation topic. I researched the history of Estonia from 1980 forward, developed the slides for the presentation, wrote a script in Russian, then presented the project to my class and university faculty.
