20130002263 | RELIABILITY ASSESSMENT OF CAPACITOR DEVICE - A method of reliability testing of a semiconductor device is described. The embodiment, includes providing a capacitor including an insulating layer interposing two conductive layers. A plurality of voltages are provided to the capacitor including providing a first voltage and a second voltage greater than the first voltage.

In an embodiment, the leakage measured while applying the second voltage indicates that a failure of the insulating layer of the capacitor has occurred. In an embodiment, the capacitor is an inter-digitated metal-oxide-metal (MOM) capacitor. The reliability testing may be correlated to TDDB test results. The reliability testing may be performed at a wafer-level. | 01-03-2013 |

20150228794 | N/P MOS FINFET PERFORMANCE ENHANCEMENT BY SPECIFIC ORIENTATION SURFACE - As will be appreciated in more detail herein, the present disclosure provides for FinFET techniques whereby a FinFET channel region has a particular orientation with respect to the crystalline lattice of the semiconductor device to provide enhanced mobility, compared to conventional FinFETs. In particular, the present disclosure provides FinFETs with a channel region whose lattice includes silicon atoms arranged on (551) lattice plane. In this configuration, the sidewalls of the channel region are particularly smooth at the atomic level, which tends to promote higher carrier mobility and higher device performance than previously achievable. | 08-13-2015 |
20150243653 | Shallow Trench Isolation Structure - A semiconductor device includes a semiconductor substrate, an active region and a trench isolation. The active region is formed in the semiconductor substrate. The trench isolation is disposed adjacent to the active region. The trench isolation includes a lower portion and an upper portion. The upper portion is located on the lower portion.

In a method for fabricating the semiconductor device, at first, the semiconductor substrate is etched to form a trench in the semiconductor substrate. Then, an insulator fills the trench to form the trench isolation. Thereafter, the gate structure is formed on the semiconductor substrate. Then, the semiconductor substrate is etched to form a recess adjacent to the trench isolation. Thereafter, at least one doped epitaxial layer grows in the recess. | 08-27-2015 |
20150262929 | AIR-GAP SCHEME FOR BEOL PROCESS - The present disclosure relates a method of forming a back-end-of-the-line (BEOL) metallization layer having an air gap disposed between adjacent metal interconnect features, which provides for an inter-level dielectric material with a low dielectric constant, and an associated apparatus. In some embodiments, the method is performed by forming a metal interconnect layer within a sacrificial dielectric layer overlying a substrate. The sacrificial dielectric layer is removed to form a recess extending between first and second features of the metal interconnect layer. A protective liner is formed onto the sidewalls and bottom surface of the recess, and then a re-distributed ILD layer is deposited within the recess in a manner that forms an air gap at a position between the first and second features of the metal interconnect layer. The air gap reduces the dielectric constant between the first and second features of the metal interconnect layer. | 09-17-2015 |
