    Abstract: An integrated circuit containing CMOS transistors and an embedded thermoelectric device may be formed by forming field oxide in isolation trenches to isolate the CMOS transistors and thermoelectric elements of the embedded thermoelectric device. N-type dopants are implanted into the substrate to provide at least 1×1018 cm−3 n-type dopants in n-type thermoelectric elements and the substrate under the field oxide between the n-type thermoelectric elements. P-type dopants are implanted into the substrate to provide at least 1×1018 cm−3 p-type dopants in p-type thermoelectric elements and the substrate under the field oxide between the p-type thermoelectric elements. The n-type dopants and p-type dopants may be implanted before the field oxide are formed, after the isolation trenches for the field oxide are formed and before dielectric material is formed in the isolation trenches, and/or after the field oxide is formed.

    Abstract: An integrated circuit containing CMOS transistors and an embedded thermoelectric device is formed by forming isolation trenches in a substrate, concurrently between the CMOS transistors and between thermoelectric elements of the embedded thermoelectric device. Dielectric material is formed in the isolation trenches to provide field oxide which laterally isolates the CMOS transistors and the thermoelectric elements. Germanium is implanted into the substrate in areas for the thermoelectric elements, and the substrate is subsequently annealed, to provide a germanium density of at least 0.10 atomic percent in the thermoelectric elements between the isolation trenches. The germanium may be implanted before the isolation trenches are formed, after the isolation trenches are formed and before the dielectric material is formed in the isolation trenches, and/or after the dielectric material is formed in the isolation trenches.

    Abstract: A microelectronic device includes a hybrid component. The microelectronic device has a substrate including silicon semiconductor material. The hybrid component includes a silicon portion in the silicon, and a wide bandgap (WBG) structure on the silicon. The WBG structure includes a WBG semiconductor material having a bandgap energy greater than a bandgap energy of the silicon. The hybrid component has a first current terminal on the silicon, and a second current terminal on the WBG semiconductor structure. The microelectronic device may be formed by forming the silicon portion of the hybrid component in the silicon, and subsequently forming the WBG structure on the silicon.

    Abstract: A method of fabricating an integrated circuit includes forming a first opening having a first width and a second opening having a second width in a first dielectric layer over a silicon substrate. The openings expose the silicon substrate and the exposed silicon substrate is oxidized to form first and second LOCOS structures having a first thickness. A polysilicon layer is formed over the silicon substrate, so that the polysilicon layer fills the first and second openings. A blanket etch of the polysilicon layer is performed to remove at least a portion of the polysilicon layer over the second LOCOS structure while leaving the first LOCOS structure protected by the polysilicon layer. The silicon substrate under the second LOCOS structure is further oxidized such that the second LOCOS structure has a second thickness greater than the first thickness.

    Abstract: A semiconductor device includes a source region. A drain region has a first conductivity type and a second dopant concentration spaced apart from the source region. A first drift region is located between the source region and the drain region and has the first conductivity type and a first dopant concentration that is lower than the second dopant concentration of the drain region. An oxide structure includes a first portion on or over the first drift region and a tapered portion between the first portion and the drain region. A substrate surface extension is between the tapered portion and the drain region. A buffer region has the first conductivity type between the first drift region and the drain region and under the tapered portion of the oxide structure. The buffer region has a third dopant concentration between the second dopant concentration and the first dopant concentration.
