Abstract: The invention relates to fill on demand ampoule refill. Methods and apparatus for use of a fill on demand ampoule are disclosed. The fill on demand ampoule may refill an ampoule with precursor concurrent with the performance of other deposition processes. The fill on demand may keep the level of precursor within the ampoule at a relatively constant level. The level may be calculated to result in an optimum head volume. The fill on demand may also keep the precursor at a temperature near that of an optimum precursor temperature. The fill on demand may occur during parts of the deposition process where the agitation of the precursor due to the filling of the ampoule with the precursor minimally effects the substrate deposition. Substrate throughput may be increased through the use of fill ondemand.

Abstract: A showerhead in a semiconductor processing apparatus can include faceplate through-holes configured to improve the flow uniformity during atomic layer deposition. The showerhead can include a faceplate having a plurality of through-holes for distributing gas onto a substrate, where the faceplate includes small diameter through-holes. For example, the diameter of each of the through-holes can be less than about 0.04 inches. In addition or in the alternative, the showerhead can include edge through-holes positioned circumferentially along a ring having a diameter greater than a diameter of the substrate being processed. The showerhead can be a low volume showerhead and can include a baffle proximate one or more gas inlets in communication with a plenum volume of the showerhead. The faceplate with small diameter through-holes and/or edge through-holes can improve overall film non-uniformity, improve azimuthal film non-uniformity at the edge of the substrate, and enable operation at higher RF powers.

Abstract: Methods and apparatuses for depositing thin films using long and short conversion times during alternating cycles of atomic layer deposition (ALD) are provided herein. Embodiments involve alternating conversion duration of an ALD cycle in one or more cycles of a multi-cycle ALD process. Some embodiments involve modulation of dose, purge, pressure, plasma power or plasma energy in two or more ALD cycles.

Abstract: Methods and apparatuses for performing atomic layer deposition are provided. A method may include determining an amount of accumulated deposition material currently on an interior region of a deposition chamber interior, wherein the amount of accumulated deposition material changes over the course of processing a batch of substrates; applying the determined amount of accumulated deposition material to a relationship between a number of ALD cycles required to achieve a target deposition thickness, and a variable representing an amount of accumulated deposition material, wherein the applying returns a compensated number of ALD cycles for producing the target deposition thickness given the amount of accumulated deposition material currently on the interior region of the deposition chamber interior; and performing the compensated number of ALD cycles on one or more substrates in the batch.

Abstract: Methods for depositing film on substrates are provided. In these embodiments, the substrates are processed in batches. Due to changing conditions within a reaction chamber as additional substrates in the batch are processed, various film properties may trend over the course of a batch. The methods herein can be used to address the trending of film properties over the course of a batch. More specifically, film property trending is minimized by changing the amount of RF power used to process substrates over the course of the batch. Such methods are sometimes referred to as RF compensation methods.
