Method of controlling the film properties of PECVD-deposited thin films

We have discovered methods of controlling a combination of PECVD deposition process parameters during deposition of thin films which provides improved control over surface standing wave effects which affect deposited film thickness uniformity and physical property uniformity. By minimizing surface standing wave effects, the uniformity of film properties across a substrate surface onto which the films have been deposited is improved. In addition, we have developed a gas diffusion plate design which assists in the control of plasma density to be symmetrical or asymmetrical over a substrate surface during film deposition, which also provides improved control over uniformity of deposited film thickness.

Electrochromic devices

Prior electrochromic devices frequently suffer from poor reliability and poor performance. Some of the difficulties result from inappropriate design and construction of the devices. In order to improve device reliability two layers of an electrochromic device, the counter electrode layer and the electrochromic layer, can each be fabricated to include defined amounts of lithium. Further, the electrochromic device may be subjected to a multistep thermochemical conditioning operation to improve performance. Additionally, careful choice of the materials and morphology of some components of the electrochromic device provides improvements in performance and reliability. In some devices, all layers of the device are entirely solid and inorganic.

Method for forming low-carbon CVD film for filling trenches

A method of forming a low-carbon silicon-containing film by CVD on a substrate having trenches includes: introducing a silicon-containing compound having three or less hydrocarbon units in its molecule and having a boiling temperature of 35° C. to 220° C.; applying RF power to the gas; and depositing a film on a substrate having trenches wherein the substrate is controlled at a temperature such that components of the silicon-containing compound are at least partially liquidified on the substrate, thereby filling the trenches with the film.

Method for energy-assisted atomic layer deposition and removal

A method for energy-assisted atomic layer deposition and removal of a dielectric film are provided. In one embodiment a substrate is placed into a reaction chamber and a gaseous precursor is introduced into the reaction chamber. Energy is provide by a pulse of electromagnetic radiation which forms radical species of the gaseous precursor. The radical species react with the surface of the substrate to form a radical terminated surface on the substrate. The reaction chamber is purged and a second gaseous precursor is introduced. A second electromagnetic radiation pulse is initiated and forms second radical species. The second radical species of the second gas react with the surface to form a film on the substrate. Alternately, the gaseous species can be chosen to produce radicals that result in the removal of material from the surface of the substrate.

Continuous method for depositing a film by modulated ion-induced atomic layer deposition (MII-ALD)

The present invention relates to an enhanced sequential atomic layer deposition (ALD) technique suitable for deposition of barrier layers, adhesion layers, seed layers, low dielectric constant (low-k) films, high dielectric constant (high-k) films, and other conductive, semi-conductive, and non-conductive films. This is accomplished by 1) providing a non-thermal or non-pyrolytic means of triggering the deposition reaction; 2) providing a means of depositing a purer film of higher density at lower temperatures; and, 3) providing a faster and more efficient means of modulating the deposition sequence and hence the overall process rate resulting in an improved deposition method.

Method of forming thin film

A method for forming a thin film includes: supplying an additive gas, a dilution gas, and a silicon-containing source gas into a reaction chamber wherein a substrate is placed; forming a thin film on the substrate by plasma CVD under a given pressure with a given intensity of radio-frequency (RF) power from a first point in time to a second point in time; at the second point in time, stopping the supply of the silicon-containing source gas; and at the second point in time, beginning reducing but not stopping the RF power, and beginning reducing the pressure, wherein the reduction of the RF power and the reduction of the pressure are synchronized up to a third point in time.

Method for producing material of electronic device

A process for producing electronic device (for example, high-performance MOS-type semiconductor device) structure having a good electric characteristic, wherein an SiO2 film or SiON film is used as an insulating film having an extremely thin (2.5 nm or less, for example) film thickness, and poly-silicon, amorphous-silicon, or SiGe is used as an electrode. In the presence of process gas comprising oxygen and an inert gas, plasma including oxygen and the inert gas (or plasma comprising nitrogen and an inert gas, or plasma comprising nitrogen, an inert gas and hydrogen) is generated by irradiating a wafer W including Si as a main component with microwave via a plane antenna member SPA. An oxide film (or oxynitride film) is formed on the wafer surface by using the thus generated plasma, and as desired, an electrode of poly-silicon, amorphous-silicon, or SiGe is formed, to thereby form an electronic device structure.

Atomic Layer Deposition For Controlling Vertical Film Growth

A method for forming a film by atomic layer deposition wherein vertical growth of a film is controlled, includes: (i) adsorbing a metal-containing precursor for film formation on a concave or convex surface pattern of a substrate; (ii) oxidizing the adsorbed precursor to form a metal oxide sub-layer; (iii) adsorbing a metal-free inhibitor on the metal oxide sub-layer more on a top / bottom portion than on side walls of the concave or convex surface pattern; and (iv) repeating steps (i) to (iii) to form a film constituted by multiple metal oxide sub-layers while controlling vertical growth of the film by step (iii). The adsorption of the inhibitor is antagonistic to next adsorption of the precursor on the metal oxide sub-layer
