  • Patent number: 12232435
    Abstract: An integrated circuit includes a substrate with an active area, a first insulating layer, a second insulating layer, and a phase-change material. The integrated circuit further includes a heating element in an L-shape, with a long side in direct physical contact with the phase-change material and a short side in direct physical contact with a via. The heating element is surrounded by first, second, and third insulating spacers, with the first insulating spacer having a planar first sidewall in contact with the long side of the heating element, a convex second sidewall, and a planar bottom face in contact with the short side of the heating element. The second and third insulating spacers are in direct contact with the first insulating spacer and the long side of the heating element.

  • Patent number: 12167703
    Abstract: An electronic chip includes at least a first array of first elementary cells and a second array of second elementary cells. The first and second elementary cells form two types of phase change memory having a storage element formed by a volume of phase change material having either a crystalline state or an amorphous state depending on the bit stored. Each first elementary cell includes a volume of a first phase change material, and each second elementary cell includes a volume of a second phase change material that is different from the first material. Each elementary cell includes a heating connector configured for the passage of a heating current adapted to cause a phase change of the volume of phase change material of the elementary cell.

  • Publication number: 20240014215
    Abstract: A method can be used for manufacturing a high-voltage transistor in and on a high-voltage region of a silicon-on-insulator type bulk that includes a semiconductor film having a first thickness, electrically insulated from a carrier bulk by a buried dielectric layer. The semiconductor film in the high-voltage region is selectively epitaxially grown to a second thickness that is greater than the first thickness while the semiconductor film remains at the first thickness in a region outside the high-voltage region.

  • Publication number: 20230387119
    Abstract: The semiconductor device of a silicon on insulator type includes a NMOS transistor in a P-type well of the carrier substrate, a PMOS transistor in an N-type well of the carrier substrate, and a power supply circuit configured to generate voltages in the P-type and N-type wells, so as to selectively provide neutral, forward and reverse back bias conditions to the NMOS transistor and the PMOS transistor. The neutral back bias condition is achieved when a first non-zero negative voltage is applied to the P-type well and a first non-zero positive voltage is applied to the N-type well. The NMOS and PMOS transistors are configured to have nominal threshold voltages in the neutral back bias condition.

  • Publication number: 20170317106
    Abstract: An integrated circuit is formed using a substrate of a silicon-on-insulator type that includes a carrier substrate and a stack of a buried insulating layer and a semiconductor film on the carrier substrate. A first region without the stack separates a second region that includes the stack from a third region that also includes the stack. An MOS transistor has a gate dielectric region formed by a portion of the buried insulating layer in the second region and a gate region formed by a portion of the semiconductor film in the second region. The carrier substrate incorporates doped regions under the first region which form at least a part of a source region and drain region of the MOS transistor.
