Patent number: 12272633Abstract: An isolation capacitor structure reduces the likelihood of breakdown in the passivation layers by physically re-shaping or dividing the top plate of the isolation capacitor into two segments. In that way, the electric field is driven down and away from the passivation surfaces. One embodiment utilizes a series capacitor formed by the top metal plate of the capacitor and an additional “top hat” plate above the top metal plate that redirects the fields into the main isolation capacitor. Vias may be included between the top hat plate and the top metal plate. Another approach reshapes the top plate to have an integrated top hat structure and achieves similar results of directing charge down and away from the passivation layer surface breakdown paths.Type: GrantFiled: December 27, 2019Date of Patent: April 8, 2025Assignee: Skyworks Solutions, Inc.Inventors: Thomas C.

Patent number: 12249642Abstract: In a vertical power device with trenched insulated gates, there is an npnp layered structure. The vertical gates turn on the device with a suitable gate bias to conduct a current between a top electrode and a bottom electrode. In an example, implanted n+ source regions are formed in the top surface within a p-well. Between some gates, the overlying dielectric is opened up, by etching, to expose distributed p-type contact regions for the p-well. The dielectric is also opened up to expose areas of the n+ source regions. The top electrode metal directly contacts the exposed p-type contact regions and the n+ source regions to provide distributed emitter-to-base short across the cellular array to improve device performance in the presence of transients. The p-contact regions are isolated from the n+ source regions, prior to the deposition of the metal electrode, due to the p-type contact regions not abutting the n+ source regions.Type: GrantFiled: May 18, 2022Date of Patent: March 11, 2025Assignee: Pakal Technologies, Inc.Inventors: Paul M Moore, Richard A Blanchard, Vladimir Rodov
