  • Patent number: 11634816
    Abstract: Provided herein are methods, systems, and devices incorporating use of materials to store, ship, and deliver process gases to micro-electronics fabrication processes and other critical process applications.
    Type: Grant
    Filed: June 2, 2020
    Date of Patent: April 25, 2023

  • Patent number: 11637243
    Abstract: Self-organizing patterns with micrometer-scale feature sizes are promising for the large area fabrication of photonic devices and scattering layers in optoelectronics. Pattern formation would ideally occur in the active semiconductor to avoid the need for further processing steps. The present disclosure includes approaches to form period patterns in single layers of organic semiconductors by an annealing process. When heated, a crystallization front propagates across the film, producing a sinusoidal surface structure with wavelengths comparable to that of near-infrared light. These surface features form initially in the amorphous region within a micron of the crystal growth front, likely due to competition between crystal growth and surface mass transport. The pattern wavelength can be tuned by varying film thickness and annealing temperature, millimeter scale domain sizes are obtained. Aspects of the disclosure can be exploited for self-assembly of microstructured organic optoelectronic devices, for example.

  • Patent number: 11154792
    Abstract: Methods for the gas-phase delivery of gases, such as process gases, from the gas phase of a multicomponent source liquid are provided. The methods are generally directed to the generation of process gases having mass flow rates which are proportional to the input power delivered to the multicomponent source liquid containers.
