Patent number: 11940495Abstract: An electronic assembly has a host wafer having a first circuit including wafer transistors and passive, non-transistor devices. Chiplets have a second circuit including at least one radio frequency (RF) transistor device. Electrical interconnects are between the chiplets and wafer. The electrical interconnects electrically connect the first circuit to the second circuits. Oscillators that have the wafer transistor, the RF transistor and the electrical interconnects produce a signal for built-in self-test circuits for testing an assembly design of the electronic assembly and speeds of the RF chiplet transistors.Type: GrantFiled: July 13, 2023Date of Patent: March 26, 2024Assignee: PseudolithIC, Inc.Inventors: James Buckwalter, Michael Hodge, Justin Kim, Daniel Green, Florian Herrault

Publication number: 20210399121Abstract: Derivative cancellation techniques have been used to linearize transistors using multiple discreet devices. However at frequencies approaching and in the mm-wave regime the use of individual devices no longer works due to the parasitics associated with combining the devices. In this invention device structures are described which apply the derivative cancellation technique in a single device thus removing the detrimental impact of combining. In one example, an N-polar transistor structure includes a channel; a cap structure comprising a plurality of cap layers on or above the channel; a source contact and a drain contact to the channel; and a castellated, stepped, or varying pattern formed in the cap layers so that gate metal deposited on the pattern forms at least two different threshold voltages and current combines in the ohmic region with essentially zero parasitic inductance.Type: ApplicationFiled: June 21, 2021Publication date: December 23, 2021Applicant: The Regents of the University of CaliforniaInventors: Brian Romanczyk, Umesh K. Mishra, Pawana Shrestha, Matthew Guidry, James Buckwalter, Stacia Keller, Rohit Reddy Karnaty
