    摘要: A technique relates to protecting a tunnel junction. A first electrode paddle and a second electrode paddle are on a substrate. The first and second electrode paddles oppose one another. A sacrificial shorting strap is formed on the substrate. The sacrificial shorting strap connects the first electrode paddle and the second electrode paddle; The tunnel junction is formed connecting the first electrode paddle and the second electrode paddle, after forming the sacrificial shorting strap. The substrate is mounted on a portion of a quantum cavity. The portion of the quantum cavity is placed in a vacuum chamber. The sacrificial shorting strap is etched away in the vacuum chamber while the substrate is mounted to the portion of the quantum cavity, such that the sacrificial shorting strap no longer connects the first and second electrode paddles. The tunnel junction has been protected from electrostatic discharge by the sacrificial shorting strap.

    摘要: In one aspect, a method of fabricating a bipolar transistor device on a wafer includes the following steps. A dummy gate is formed on the wafer, wherein the dummy gate is present over a portion of the wafer that serves as a base of the bipolar transistor. The wafer is doped to form emitter and collector regions on both sides of the dummy gate. A dielectric filler layer is deposited onto the wafer surrounding the dummy gate. The dummy gate is removed selective to the dielectric filler layer, thereby exposing the base. The base is recessed. The base is re-grown from an epitaxial material selected from the group consisting of: SiGe, Ge, and a III-V material. Contacts are formed to the base. Techniques for co-fabricating a bipolar transistor and CMOS FET devices are also provided.

    摘要: Self-aligned pitch split techniques for metal wiring involving a hybrid (subtractive patterning/damascene) metallization approach are provided. In one aspect, a method for forming a metal wiring layer on a wafer includes the following steps. A copper layer is formed on the wafer. A patterned hardmask is formed on the copper layer. The copper layer is subtractively patterned using the patterned hardmask to form a plurality of first copper lines. Spacers are formed on opposite sides of the first copper lines. A planarizing dielectric material is deposited onto the wafer, filling spaces between the first copper lines. One or more trenches are etched in the planarizing dielectric material. The trenches are filled with copper to form a plurality of second copper lines that are self-aligned with the first copper lines. An electronic device is also provided.
