Номер: CA2745517A1
Автор: Damien G. Loveland
Принадлежит: Individual

An assembly puzzle comprising different polycubes that can be arranged to form a cube comprising sixty-four unit cubes. Included in the puzzle are polycubes of a sufficiently distributed complexity to allow meaningful hints to be given without actually providing a solution. Furthermore, the polycubes can be arranged in different configurations to build a wide variety of shapes other than a cube.

Super long channel device within VFET architecture

Номер: US10833190B2
Принадлежит: International Business Machines Corp

Embodiments are directed to methods and resulting structures for a vertical field effect transistor (VFET) having a super long channel. A pair of semiconductor fins is formed on a substrate. A semiconductor pillar is formed between the semiconductor fins on the substrate. A region that extends under all of the semiconductor fins and under part of the semiconductor pillar is doped. A conductive gate is formed over a channel region of the semiconductor fins and the semiconductor pillar. A surface of the semiconductor pillar serves as an extended channel region when the gate is active.

Method and structure for enabling controlled spacer RIE

Номер: US9627277B2
Принадлежит: International Business Machines Corp

A method and structure to enable reliable dielectric spacer endpoint detection by utilizing a sacrificial spacer fin are provided. The sacrificial spacer fin that is employed has a same pitch as the pitch of each semiconductor fin and the same height as the dielectric spacers on the sidewalls of each semiconductor fin. Exposed portions of the sacrificial spacer fin are removed simultaneously during a dielectric spacer reactive ion etch (RIE). The presence of the sacrificial spacer fin improves the endpoint detection of the spacer RIE and increases the endpoint signal intensity.

Single spacer for complementary metal oxide semiconductor process flow

Номер: US9450095B1
Принадлежит: International Business Machines Corp

A method of forming a semiconductor device that includes forming a high-k dielectric fin liner on the first plurality of fin structures in a first device region and a second plurality of fin structures in a second device region, and forming a gate structure including a low-k dielectric gate sidewall spacer on the channel region of the first and second plurality of fin structures. A first epitaxial semiconductor material on the first plurality of fin structures from which the high-k dielectric fin liner has been removed. The first epitaxial semiconductor material is then oxidized, and a remaining portion of the high-k dielectric fin liner is removed. A second epitaxial semiconductor material is formed on the second plurality of fin structures.
