  • Publication number: 20240110284
    Abstract: A method of processing a substrate is disclosed which includes depositing a layer in a processing chamber on a field region, a sidewall region, and a fill region of a feature of the substrate, wherein a hardness of a portion of the layer deposited on the sidewall region is lower than a hardness of a portion of the layer deposited on the field region, and lower than a hardness of a portion of the layer deposited on the fill region.

  • Publication number: 20220122873
    Abstract: Exemplary semiconductor processing systems include a processing chamber, a power supply, and a chuck disposed at least partially within the processing chamber. The chuck includes a chuck body defining a vacuum port. The chuck also includes first and second coplanar electrodes embedded in the chuck body and connected to the power supply. In some examples, coplanar electrodes include concentric electrodes defining a concentric gap in between. Exemplary semiconductor processing methods may include activating the power supply for the electrostatic chuck to secure a semiconductor substrate on the body of the chuck and/or activating the vacuum port defined by the body of the electrostatic chuck. Some processing can be carried out at increased pressure, while other processing can be carried out at reduced pressure with increased chucking voltage.

  • Publication number: 20180350563
    Abstract: Embodiments of the disclosure generally relate to a method of processing a semiconductor substrate at a temperature less than 250 degrees Celsius. In one embodiment, the method includes loading the substrate with the deposited film into a pressure vessel, exposing the substrate to a processing gas comprising an oxidizer at a pressure greater than about 2 bars, and maintaining the pressure vessel at a temperature between a condensation point of the processing gas and about 250 degrees Celsius.

  • Patent number: 9472392
    Abstract: Silicon oxide is deposited with improved step coverage by first exposing a patterned substrate to a silicon-containing precursor and then to an oxygen-containing precursor or vice versa. Plasma excitation is used for both precursors. Exposing the precursors one-at-a-time avoids disproportionate deposition of silicon oxide near the opening of a high aspect ratio gap on a patterned substrate. The plasma-excited precursors exhibit a lower sticking coefficient and/or higher surface diffusion rate in regions already adsorbed and therefore end up depositing silicon oxide deep within the high aspect ratio gap to achieve the improvement in step coverage.

  • Patent number: 9362111
    Abstract: Implementations described herein generally relate to methods for forming dielectric films in high aspect ratio features. In one implementation, a method for forming a silicon oxide layer is provided. A silicon-containing precursor gas is flown into a processing chamber having a substrate having a high aspect ratio feature disposed therein. Then a high frequency plasma is applied to the silicon-containing precursor gas to deposit a silicon-containing layer over the surface of the high aspect ratio feature. The processing chamber is purged to remove by-products from the silicon-containing layer deposition process. An oxygen-containing precursor gas is flown into the processing chamber. A high frequency plasma and a low frequency plasma are applied to the oxygen-containing precursor gas to form the silicon oxide layer.
