Novel Thermal Atomic Layer Etching Methods for Isotropic and Anisotropic Etching
Prof. Steve George at the University of Colorado is developing new approaches to atomic layer etching (ALE), a thin film removal technique based on sequential, self-limiting surface reactions. These new thermal ALE methods offer exceptional control over etching because they can remove material quantitatively at the angstrom (1 x 10-10 m) level. Furthermore, unlike the current etching methods based on sputtering, the thermal ALE approaches are gentle and do not damage the surface. Thermal ALE is isotropic and does not require line-of-sight to the substrate. However, enhancements to thermal ALE can be obtained through the removal of certain adsorbed surface species, allowing for anisotropic etching. A combination of isotropic and anisotropic etching methods will be needed for many steps in advanced semiconductor manufacturing. Specifically, anisotropic etching is important for the fabrication of 3D device structures. Thermal ALE has been demonstrated on a variety of surfaces including metal oxides, metal nitrides, metal fluorides, and elemental metals.
Microbial Electrolytic Process for Carbon Capture, Energy Production and Waste Treatment
A new approach to treating wastewater using microbial electrolytic carbon capture. This process generates positive energy, chemicals (carbonate or liquid fuel), and reusable water. It also directly captures carbon dioxide which generates additional carbon credits and environmental benefits.
Method and device for tensile testing of cable bundles
AFRL has developed a standard tensile test device that is improved to accurately measure the mechanical properties of stranded cables, ropes, and other composite structures. In this device, a witness is attached to the top and bottom mounting blocks holding the cable under test.
Device for testing thin specimens in pure bending
AFRL has developed an improved test fixture to evaluate thin composite laminates commonly used in deployable space structures. The fixture is designed to impart a pure moment into the coupon, a necessary improvement to prior test methods where results are obtained by fitting material properties in a nonlinear structural analysis of the test.
Combined plasma source and liner implosion system
AFRL has developed a novel arrangement that combines in a single compact embodiment a plasma flow switch source of ultrahigh speed plasma and an electromagnetically-imploded cylindrical shell.
Synthesis of (Ga1-xZnx)(N1-xOx) Nanocrystals for Photocatalytic Waters Splitting
An improved method of (Ga1-xZnx)(N1-xOx) nanocrystal production. The nanocrystals are tunable, are single crystalline, and have a smaller band gap. There is a 260% increase in solar photon absorption enabling improved water splitting quantum yields.
Flexible Circuit US PATENT # 7,452,746 | US PATENT # 6,017,822
This invention is a method of fabricating flexible organic integrated circuits (ICs) such as flexible substrates used for large area displays, identification tags, electronic paper, etc. This technology enables assembly of ICs requiring high temperature processes, which in turn enables higher system performance at lower power consumption rates.
Reusable Tamper-Evident Bag
This invention provides the ability to initiate round trip courier services without including supplemental supplies or complex procedures. The technology provides couriers a tamper-indicating bag that can be reused while still maintaining a characteristic level of confidentiality and security. The dual-seal characteristic of this container allows items to be outbound couriered, the primary seal inspected and certified by a recipient, and a return trip initiated using the container’s secondary seal.
