  • Patent number: 9793394
    Abstract: Integrated circuits including LDMOS transistor structures and methods for fabricating LDMOS transistor structures are provided. An exemplary method for fabricating an LDMOS transistor structure includes providing a semiconductor-on-insulator (SOI) substrate including a semiconductor layer overlying an insulator layer overlying a bulk layer. The method includes forming a gate structure overlying the substrate. A channel region is formed in the semiconductor layer under the gate structure. The method includes forming a source region overlying the substrate. Further, the method includes forming a drain region overlying the substrate. A drift region is located between the drain region and the gate structure. Also, the method includes forming contacts to the gate structure, the source region, and the drain region.

  • Patent number: 9780231
    Abstract: Integrated circuits and methods of producing such integrated circuits are provided. In an exemplary embodiment, an integrated circuit includes a substrate with an active layer overlying a handle layer. A partial buried insulator overlies the handle layer and underlies the active layer, terminates at a buried insulator termination point, and includes an electrically insulating material. A substrate extension is adjacent to the partial buried insulator, where the substrate extension overlies the handle layer and underlies the active layer, and where the substrate extension directly contacts the partial buried insulator at the buried insulator termination point. The substrate extension includes a semiconductive material. A memory gate overlies the active layer.

  • Patent number: 9698200
    Abstract: A device and a method of forming a device are disclosed. The method includes providing a substrate defined with first and second functional regions and first and second non-functional regions. The first non-functional region corresponds to a proximate memory region which is proximate to and surrounds the first functional region and the second non-functional region corresponds to an external logic circuit region which surrounds at least the second functional region. A magnetic memory element is formed in the first functional region and a logic element is formed in the second functional region. A plurality of magnetism controllable dummy structures are formed in the proximate memory region and external logic circuit region. The magnetism controllable dummy structures provide uniform magnetic field to the magnetic memory element and prevents electrical-magnetic interaction between the magnetic memory and logic elements on the same substrate.

  • Patent number: 9583499
    Abstract: Devices and methods for fabricating devices with floating gates and replacement metal gates are provided. In an embodiment, a method for fabricating a device includes providing a semiconductor substrate. The method forms a floating gate and a sacrificial gate over the semiconductor substrate. Further, the method replaces the sacrificial gate with a metal gate. After replacing the sacrificial gate with the metal gate, the method forms a control gate over the floating gate.
