摘要:
A semiconductor component includes a semiconductor substrate having a top surface. An opening extends from the top surface into the semiconductor substrate. The opening includes an interior surface. A first dielectric liner having a first compressive stress is disposed on the interior surface of the opening. A second dielectric liner having a tensile stress is disposed on the first dielectric liner. A third dielectric liner having a second compressive stress disposed on the second dielectric liner. A metal barrier layer is disposed on the third dielectric liner. A conductive material is disposed on the metal barrier layer and fills the opening.
摘要:
A multi-step anneal method is provided. First, a substrate is provided. Then, a dielectric layer comprising a damascene structure is formed over the substrate, and a barrier/seed layer is formed over the damascene structure. Next, a metal layer is formed over the barrier layer, and performing a first anneal step in-situ to anneal the substrate at a first temperature range with a first environment. Thereafter, a metal chemical mechanical polish (CMP) step is performed to remove a portion of the metal layer until a portion of the barrier layer is exposed. Then, a second anneal step is performed to anneal the substrate at a second temperature range with a second environment.
摘要:
Capacitor designs for substrates, such as interposers, and methods of manufacture thereof are disclosed. A through via is formed in the interposer, and a capacitor is formed between a lower level metallization layer and a higher level metallization layer. The capacitor may be, for example, a planar capacitor with dual capacitor dielectric layers.

A semiconductor structure includes a through-substrate-via (TSV) structure disposed in a substrate. A first etch stop layer is disposed over the TSV structure. A first dielectric layer is disposed in contact with the first etch stop layer. A first conductive structure is disposed through the first etch stop layer and the first dielectric layer. The first conductive structure is electrically coupled with the TSV structure. The TSV structure is substantially wider than the first conductive structure. A second etch stop layer is disposed in contact with the first dielectric layer. A metal-insulator-metal (MIM) capacitor structure is disposed in contact with the second etch stop layer.
