In LPCVD a vacuum is used. Thin films of silicon nitride (Si 3 N 4), silicon oxynitride (SiON), SiO 2 und tungsten (W) can be created. LPCVD processes enable a high conformity of almost 1. This is because of the low pressure of 10 to 100 Pa (atmospheric pressure = 100.000 Pa) which leads to a non-uniform movement of the particles.

Furthermore; plasma deposition of silicon oxide at use of the triode configuration allows, like the deposition of plasma nitride, the adjustment of the layer tension (stress control). Stress is usually created by deposition of thicker layers, which may lead to a deflection of the whole wafer and is particulary disturbing at MEMS processes.

Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state to a solid state on a substrate. Chemical reactions are involved in the process, which occur after creation of a plasma of the reacting gases. The plasma is generally created by radio frequency (RF) (alternating current (AC)) frequency or direct current (DC ...

Our PECVD nitride can be a great alternative to LPCVD nitride when it becomes important to stay within lower temperature ranges. Widely used in MEMS and semiconductor processing, PECVD nitride is a tensile stress film that can be used as a passivation layer or to help balance film stress within a stack.

The PECVD or plasma-polymerization process is mainly used for the preparation of inorganic, hybrid or polymer-like thin layers. In the field of membranes, most of the plasma deposits are prepared from organic precursors; in that case, one calls the deposition process plasma polymerization preferentially to PECVD.

Atomic layer deposition of ruthenium on SrTiO3 layers was investigated using (C2H5C5H4) · (NC4H4) Ru and air as precursors. For comparison, the growth was studied also on ZrO2 films and SiO2/Si surfaces. Deposition temperature was 325 °C. Using rather short but intense air pulses, smooth and uniform Ru films were deposited on SrTiO3.

 · Low pressure chemical vapor deposition (LPCVD) is a chemical vapor deposition technology that uses heat to initiate a reaction of a precursor gas on the solid substrate. This reaction at the surface is what forms the solid phase material. Low pressure (LP) is used to decrease any unwanted gas phase reactions, and also increases the uniformity across the substrate.

Aluminum reacts with silicon at a few hundred °C to form a eutectic alloy; this will cause "spikes" of alloy to penetrate into the silicon if a direct Al-Si contact is made. Alloyed contacts were used in the 70's and 80's for IC's, but as junctions grew thinner the "spikes" would penetrate through the source or drain layer and cause shorts to the body.
