    Abstract: Disclosed examples include microelectronic devices, e.g. Integrated circuits. One example includes a microelectronic device including a nanosheet lateral drain extended metal oxide semiconductor (LDMOS) transistor with source and drain regions having a first conductivity type extending into a semiconductor substrate having an opposite second conductivity type. A superlattice of alternating layers of nanosheets of a channel region and layers of gate conductor are separated by a gate dielectric, the superlattice extending between the source region and the drain region. A drain drift region of the first conductivity type extends under the drain region and a body region of the second type extends around the source region.

    Abstract: An integrated circuit includes a photodetector that has an epitaxial layer with a first conductivity type located over a substrate. A buried layer of the first conductivity type is located within the epitaxial layer and has a higher carrier concentration than the epitaxial layer. A semiconductor layer located over the buried layer has an opposite second conductivity type and includes a first sublayer over the buried semiconductor layer and a second sublayer between the first sublayer and the buried layer. The first sublayer has a larger lateral dimension than the second sublayer, and has a lower carrier concentration than the second sublayer.

    Abstract: An integrated circuit has a P-type substrate and an N-type LDMOS transistor. The LDMOS transistor includes a boron-doped diffused well (DWELL-B) and an arsenic-doped diffused well (DWELL-As) located within the DWELL-B. A first polysilicon gate having first sidewall spacers and a second polysilicon gate having second sidewall spacers are located over opposite edges of the DWELL-B. A source/IBG region includes a first source region adjacent the first polysilicon gate, a second source region adjacent the second polysilicon gate, and an integrated back-gate (IBG) region located between the first and second source regions. The first source region and the second source region each include a lighter-doped source sub-region, the IBG region including an IBG sub-region having P-type dopants, and the source/IBG region includes a heavier-doped source sub-region.
