Patent number: 11823899Abstract: A high-temperature silicon carbide device, along with an integrated circuit including the device and method of fabricating the device are described. For example, the method includes forming one of a source region and a drain region of a silicon carbide metal-oxide-semiconductor device. The method may include forming a gate structure adjacent to either one of the source region and the drain region. The gate structure may include an insulating layer. The method may further include forming the insulating layer with a first growth step performed in a pure oxygen environment and with a second growth step performed in a nitrous oxide environment.Type: GrantFiled: April 15, 2021Date of Patent: November 21, 2023Assignee: CoolCAD Electronics, LLCInventors: Neil Goldsman, Akin Akturk, Zeynep Dilli, Mitchell Adrian Gross, Aysanew Abate

Patent number: 11798938Abstract: A SiC integrated circuit structure which allows multiple power MOSFETs or LDMOSs to exist in the same piece of semiconductor substrate and still function as individual devices which form the components of a given circuit architecture, for example, and not by limitation, in a half-bridge module. In one example, a deep isolation trench is etched into the silicon carbide substrate surrounding each individual LDMOS device. The trench is filled with an insulating material. The depth of the trench may be deeper than the thickness of an epitaxial layer to ensure electrical isolation between the individual epitaxial layer regions housing the individual LDMOSs. The width of the trench may be selected to withstand the potential difference between the bias levels of the body regions of neighboring power LDMOS devices.Type: GrantFiled: November 23, 2021Date of Patent: October 24, 2023Assignee: CoolCAD Electronics, LLCInventors: Neil Goldsman, Akin Akturk, Zeynep Dilli, Mitchell Adrian Gross, Usama Khalid, Christopher James Darmody

Patent number: 8040291Abstract: An F-inverted compact antenna for ultra-low volume Wireless Sensor Networks is developed with a volume of 0.024?×0.06?×0.076?, ground plane included, where ? is a resonating frequency of the antenna. The radiation efficiency attained is 48.53% and the peak gain is ?1.38 dB. The antenna is easily scaled to higher operating frequencies up to 2500 MHz bands with comparable performance. The antenna successfully transmits and receives signals with tolerable errors. It includes a standard PCB board with dielectric block thereon and helically contoured antenna wound from a copper wire attached to the dielectric block and oriented with the helix axis parallel to the PCB. The antenna demonstrates omnidirectional radiation patterns and is highly integratable with WSN, specifically in Smart Dust sensors. The antenna balances the trade offs between performance and overall size and may be manufactured with the use of milling technique and laser cutters.Type: GrantFiled: May 22, 2009Date of Patent: October 18, 2011Assignee: University of MarylandInventors: Bo Yang, Felice M.

Patent number: 7286359Abstract: A cooling device for a microcircuit provides a direct path of thermal extraction from a high heat producing area to a cooler area. A thermal insulation layer is formed on a body having at least one component thereon that generates the high heat producing area. At least one via is formed through an entire thickness of the insulation layer and is in direct communication with the high heat producing area. Heat from the high heat producing area is channeled through each via to the cooler area, which may be ambient atmosphere or a good thermal conductor, such as a heat sink. A thermal conductive material may be deposited within the via and increase the rate of thermal extraction therethrough.Type: GrantFiled: May 11, 2004Date of Patent: October 23, 2007Assignee: The U.S. Government as represented by the National Security AgencyInventors: Michael Khbeis, George Metze, Neil Goldsman, Akin Akturk
