  • Publication number: 20240145583
    Abstract: A method for manufacturing a SONOS memory discloses forming first a thin oxide layer as a sidewall protection layer and a blocking layer. This layer prevents the high dielectric-constant layer at the bottom of the stacked gate structure from being exposed on the surface. An lightly doped drain (LDD) implantation area is defined by a lateral thickness of a thin oxide layer, so that the channel width may be controlled by controlling the thickness of the thin oxide layer. Thus, the width of a current channel at the bottom of a gate is reduced under the same ion implantation condition into the active area, thereby improving a current capacity of the SONOS memory without adding any mask or photolithography step, and thus bring no additional patterning costs or active area ion implantation costs.

  • Patent number: 11431160
    Abstract: A hybrid circuit interrupter can be used for medium voltage direct current applications, among other applications. The circuit breaker includes a vacuum circuit interrupter and an electronic power interrupter that are electrically connected in parallel. The vacuum circuit interrupter is normally closed and the electronic power interrupter is normally off, so that current passes through the vacuum circuit interrupter in a non-interrupt mode. When an interrupt condition is detected, the electronic interrupter will turn on, and current will pass through the electronic interrupter as the vacuum interrupter is opened. A current injector may draw current from the vacuum interrupter to the electronic power interrupter. An isolation switch may maintain the system in a non-conducting state when interruption is complete.

  • Patent number: 11183348
    Abstract: A circuit breaker includes a vacuum interrupter having a closed position and an open position. The circuit breaker includes a linkage operatively coupled to and extending from the vacuum interrupter and a high-speed actuator operatively connected to the linkage. The high-speed actuator is operable to move the linkage by a repulsion force and cause the vacuum interrupter to move to the open position. The circuit breaker includes a decelerator with an integrated latch assembly operatively coupled to the high-speed actuator. The decelerator decelerates the repulsion force of the high-speed actuator and latches the actuator with the integrated latch assembly to maintain the vacuum interrupter in the open position.

  • Patent number: 10923298
    Abstract: A circuit breaker includes a compact pole unit with an encapsulated body having ring(s) and conducting terminals that each extend from the encapsulated body. The body includes a vacuum interrupter and a coupler assembly that may be integrated into the pole unit. The coupler assembly includes a contact spring positioned an end of the compact pole unit, as well as a plunger that may be biased by the contact spring. The circuit breaker also includes an actuator positioned at the end of the pole unit that is opposite the coupler assembly. The circuit breaker also may include a second actuator that is will be connected to the contact spring of the coupler assembly via the plunger, and if so the breaker may be operated via either actuator.
