Abstract: A method for manufacturing a super-junction MOSFET entails forming a recessed shield electrode in a trench in a semiconductor layer of a substrate, the trench being lined with a first oxide layer. When the electrically conductive material forming the shield electrode is removed to recess the shield electrode, the first oxide layer on sidewalls of the trench is exposed. Removal of the first oxide layer from the sidewalls and from shield sidewalls of the electrode produces openings at a top part of the shield sidewalls. A second oxide layer is formed over the shield electrode and fills the openings. Part of the second oxide layer is removed to expose a top surface of the shield electrode. A gate dielectric is formed over the top surface of the shield electrode and conductive material is deposited over the gate dielectric in the trench to form a gate electrode of the MOSFET.

Abstract: The present disclosure describes apparatuses and methods for dynamic interference cancellation in wireless receivers. In some aspects, a signal vector transmitted through a wireless environment is received via multiple antennas of a receiver, the signal vector affected by interfering signals in the wireless environment. The receiver determines an interference channel matrix for the signal vector based on the interference received with the signal vector and selects, from the interference channel matrix, columns of the interference channel matrix to form a noise-cancelling equalization matrix. The receiver then equalizes the signal vector with the noise-cancelling equalization matrix to remove a portion of interference from the signal vector to provide noise-cancelled equalized values of the signal vector for decoding. By so doing, the receiver may reduce effects of interference of the wireless environment (e.g.
