In this work, we present a systematic investigation of plasma etching of Cr2O3 films via an inductively coupled plasma-reactive ion etching system in nanoscale. The effects of plasma composition, rf-chuck power and ICP source power on the etch rates, sidewall profile, surface roughness, selectivity and dc-bias have been systematically investigated.

The Electronic Materials Conference (EMC) is the premier annual forum on the preparation, characterization and use of electronic materials. This year’s event will feature a plenary session, topical sessions, a poster session and more.

EMC is coordinated with the Device Research Conference (DRC). This recognizes the strong interaction between device and electronic materials research and provides fruitful exchange of information between attendees of both Conferences.

poster

The International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication (EIPBN), affectionately known as "3-Beams," is the premier gathering of scientists and engineers who are dedicated to electron, ion and photon lithography, imaging, and analysis; atomically precise fabrication; nanofabrication process technologies and related emerging technologies; and their applications in a broad spectrum of fields. In its 64th meeting, researchers from academia, government laboratories, and industry from around the world meet to present and discuss recent and future trends in these technologies.

We will discuss our use of ZnO nanoparticle-based thin films synthesized and grown at room temperature and deposited via electrophoretic deposition (EPD) onto p-doped silicon substrates.  Our experimentation plan includes using scanning electron microscopy to assess surface morphology and current-voltage characterization of ZnO/p-Si heterojunctions to study device performance potential.

We present results clearly demonstrating passive gradient-driven droplet motion on coating-free all-metal Al-surfaces, produced via laser-etching method.

Applications of electrospinning (ES) fabrication are broad and limited by hardware. Here, we present an ES system that contains multiple high voltage power supplies and enables high control over nanofiber placement, resulting in deposition of materials that have novel structures on the mesoscale.

Highly Controlled Deposition with Multiple Electrode Electrospinning

Our goal is to demonstrate a process flow for TSV (nozzle) on one end and another opening (reservoir) on the other end of an SOI. This silicon die will be used as a micro chemical vapor deposition (CVD) chamber, which is a critical component in the nanoscale additive writing process.

We developed a versatile room-temperature metal printing technique based on polymer-assisted photochemical deposition (PPD). We demonstrate printing of metal structures with feature sizes as small as 5µm on various substrates, and prove the concept of creating metal-based color filter using PPD.

Additive Manufacturing towards Color Printing via Polymer-Assisted Photochemical Deposition of Metal Thin Films

The heavy metals are poisonous due to inability to decompose and bioaccumulation hence, among the cost well-known environmental pollutant.  Fluorescent based approach has gained considerable attention because of real time monitoring. Aiming at developing an ideal fluorescent sensing platform for heavy metals we synthesized bimetallic MOF for the first time.

Here we demonstrate a new type of magnetically responsive nanostructure consisting of a polydimethylsiloxane (PDMS) nanopillar array with deposited nickel caps, that has successfully achieved such decoupling with multiple cap-geometry designs for a better actuation control.

we have proposed a hybrid machine learning system that presents the optimum materials and process conditions for direct nanoimprint.　The system applied for optimization of Glycol concentration to PVA for low temperature process and the results agree with experiments.

Process and material design using hybrid machine learning for direct thermal nanoimprint

New resists are required to advance the nanoelectronics industry to keep up the demands of Moore’s law. A new class of high dry etch selectively electron beam resist materials have been developed that are based on a family of heterometallic rings.

Improving the Sensitivity of Metallic Organic Resists

Maskless Grayscale lithography is a key technology to create structured surfaces in photoresist, especially for micro-optic applications. Processes of low-contrast positive resist are well known and used for thicknesses up to 60 µm. The possibility to fabricate higher structures, i.e. 80 µm, 100 µm high and beyond, are of great interest in the micro-optic world. With some double- and triple-coated layers of an experimental resist, we could make structures 83µm and 100µm tall. The triple- coated layer showed some limitations that we plan to overcome to go beyond 100µm.
