Disclosed examples include integrated circuits and bipolar transistors with a first region of a first conductivity type in a substrate, a collector region of a second conductivity type disposed in the substrate, and a base region of the first conductivity type extending into the first region. A first emitter region of the second conductivity type extends into the first region and includes a lateral side spaced from and facing the base region. A second emitter region of the second conductivity type extends downward into the first region, abutting the top surface and an upper portion of the first lateral side of the first emitter region to mitigate surface effects and gain degradation caused by hydrogen injection from radiation to provide a radiation hardened bipolar transistor.

Radiation enhanced bipolar transistor

A semiconductor device includes an integrated circuit attached to a chip carrier in a flip chip configuration. A substrate extends to a back surface of the integrated circuit, and an interconnect region extends to a front surface of the integrated circuit. A substrate bond pad is disposed at the front surface, and is electrically coupled through the interconnect region to the semiconductor material. The chip carrier includes a substrate lead at a front surface of the chip carrier. The substrate lead is electrically coupled to the substrate bond pad. An electrically conductive compression sheet is disposed on the back surface of the integrated circuit, with lower compression tips making electrical contact with the semiconductor material in the substrate. The electrically conductive compression sheet is electrically coupled to the substrate lead of the chip carrier by a back surface shunt disposed outside of the integrated circuit.

Flip chip backside mechanical die grounding techniques

Disclosed examples include semiconductor devices and fabrication methods to fabricate semiconductor wafers and integrated circuits, including forming a first epitaxial semiconductor layer of a first conductivity type on a first side of a semiconductor substrate of the first conductivity type, forming a nitride or oxide protection layer on a top side of the first epitaxial semiconductor layer, forming a second epitaxial semiconductor layer of the first conductivity type on the second side of the semiconductor substrate, and removing the protection layer from the first epitaxial semiconductor layer. The wafer can be used to fabricate an integrated circuit by forming a plurality of transistors at least partially on the first epitaxial semiconductor layer.

Process enhancement using double sided epitaxial on substrate

An integrated circuit is attached to a chip carrier in a flip chip configuration. An electrically conductive conformal layer is disposed on a back surface of the substrate of the integrated circuit. The electrically conductive conformal layer contacts the semiconductor material in the substrate and extending onto, and contacting, a substrate lead of the chip carrier. The substrate lead of the chip carrier is electrically coupled to a substrate bond pad of the integrated circuit. The substrate bond pad is electrically coupled through an interconnect region of the integrated circuit to the substrate of the integrated circuit. A component is attached to the chip carrier and covered with an electrically insulating material. The electrically conductive conformal layer also extends at least partially over the electrically insulating material on the component. The electrically conductive conformal layer is electrically isolated from the component by the electrically insulating material on the component.

Flip chip backside die grounding techniques

A method and apparatus are presented for reducing the methanol content in a fermented solution to create forms healthier to human consumption, thereby reducing headaches and hangovers. In accordance with the disclosed embodiments, the fermented solution is placed in a vacuum vessel and heated to a fixed temperature. Pulling a fixed vacuum within the vessel lowers the boiling point of the solution, creating a vapor selectively of the low-end congeners, for example, methanol. The methanol-rich vapor is condensed and disposed leaving a healthier fermented solution with reduced methanol content. In some embodiments, the fixed temperature is lower than or equal to 32 degrees C. which preserves the aroma and taste of the fermented solution.

Methanol slicing of wine

An integrated circuit is formed by providing a heavily doped substrate of a first conductivity type, forming a lightly doped lower epitaxial layer of the first conductivity type over the substrate, implanting dopants of the first conductivity type into the lower epitaxial layer in an area for a shallow component and blocking the dopants from an area for a deep component, forming a lightly doped upper epitaxial layer over the lower epitaxial layer and activating the implanted dopants to form a heavily doped region. The shallow component is formed over the heavily doped region, and the deep component is formed outside the heavily doped region, extending through the upper epitaxial layer into the lower epitaxial layer.

Radiation hardened NMOS devices suitable for application in NMOS, CMOS, or BiCMOS integrated circuits, and methods for fabricating them. A device includes a p-type silicon substrate, a field oxide surrounding a moat region on the substrate tapering through a Bird's Beak region to a gate oxide within the moat region, a heavily-doped p-type guard region underlying at least a portion of the Bird's Beak region and terminating at the inner edge of the Bird's Beak region, a gate included in the moat region, and n-type source and drain regions spaced by a gap from the inner edge of the Bird's Beak and guard regions. A variation of minor alterations to the conventional moat and n-type source/drain masks. The resulting devices have improved radiation tolerance while having a high breakdown voltage and minimal impact on circuit density.
