Patent number: 11749716Abstract: A semiconductor device includes a semiconductor body having a base region incorporating a field stop zone where the base region and the field stop zone are both formed using an epitaxial process. Furthermore, the epitaxial layer field stop zone is formed with an enhanced doping profile to realize improved soft-switching performance for the semiconductor device. In some embodiments, the enhanced doping profile includes multiple doped regions with peak doping levels where a first doped region adjacent to a first side of the field stop zone has a first peak doping level that is not higher than a last peak doping level of a last doped region adjacent to the base region. The epitaxial layer field stop zone of the present invention enables complex field stop zone doping profiles to be used to obtain the desired soft-switching characteristics in the semiconductor device.Type: GrantFiled: May 4, 2021Date of Patent: September 5, 2023Assignee: Alpha and Omega Semiconductor (Cayman) Ltd.Inventors: Lei Zhang, Karthik Padmanabhan, Lingpeng Guan, Jian Wang, Lingbing Chen, Wim Aarts, Hongyong Xue, Wenjun Li, Madhur Bobde

Patent number: 11692636Abstract: The present disclosure relates to a hydrostatically adjustable flow control valve. In one embodiment, the valve includes a fixed sleeve that slidably receives a spool. A spring biases the spool relative to the fixed sleeve. A primary orifice is used to deliver fluid to the interior area of the fixed sleeve and spool. A control device is used to selectively vary the rate at which fluid drains from the interior area. Draining the fluid results in the spool being received within the interior of the fixed sleeve. The movement of the spool opens flow ports within the sleeve. This, in turn, allows fluid to exit the valve. Conversely, the control device can be set to prevent fluid drainage. This results in the spool extending from interior of the fixed sleeve, the closure of the flow ports, and the sealing of the valve.Type: GrantFiled: November 20, 2020Date of Patent: July 4, 2023Assignee: FLOW DYNAMICS, LLCInventor: Jeffrey Alan Chalfin

Patent number: 11637243Abstract: 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.Type: GrantFiled: May 22, 2020Date of Patent: April 25, 2023Assignee: Regents of the University of MinnesotaInventors: Russell J.
