  • Publication number: 20240136406
    Abstract: A silicon carbide device includes: a transistor cell having a stripe-shaped trench gate structure extending from a first surface into a silicon carbide body, the gate structure having a gate length along a lateral first direction, a bottom surface and a first gate sidewall of the gate structure being connected via a first bottom edge of the gate structure; at least one source region of a first conductivity type in contact with the first gate sidewall; and a shielding region of a second conductivity type in contact with the first bottom edge of the gate structure across at least 20% of the gate length. No source regions of the first conductivity type are in contact with a second gate sidewall of the gate structure.

  • Patent number: 11680751
    Abstract: A stacked-plate heat exchanger may include a plurality of stacked plates. The plurality of stacked plates may include a plurality of first stacked plates and a plurality of second stacked plates stacked alternately one on top of another. Pairs of adjacent stacked plates may each delimit one of a first cavity for the passage of a first fluid and a second cavity for the passage of a second fluid in an alternating manner. The heat exchanger may also include a support structure that may support the plurality of stacked plates in an edge region to stabilize the second cavity. The plurality of stacked plates may each include a first opening and at least two second openings arranged around the first opening. The heat exchanger may also include a plurality of webs each arranged between two adjacent second openings. The plurality of webs may form the support structure.
