  • Publication number: 20240060860
    Abstract: A distribution unit of a particle detection system initiates a particle collection process to dislodge one or more surface particles from a surface of an article based on a stream including at least one of solid CO2 particles or CO2 droplets. The dislodged surface particles are collected on a surface of a substrate having a pre-determined initial state including initial surface particles of the substrate. A measurement indicating a particle number concentration of detectable surface particles on the substrate after the particle collection process is completed is obtained. An initial particle number concentration of the initial surface particles of the pre-determined initial state is identified. A number of particles transported away from the surface of the article is determined based on the obtained measurement and the identified initial particle concentration.

  • Patent number: 11815436
    Abstract: A stream including at least one of solid CO2 particles or CO2 droplets is directed toward an article including surface particles. The stream causes at least a portion of the surface particles on the article to dislodge from a surface of the article. A purge cycle to transport at least a portion of the dislodged surface particles away from the surface of the article is initiated. The purge cycle includes generating a laminar flow at a first velocity for a first time period and subsequently generating a laminar flow at a second velocity for a second time period. A determination is made of whether a number of particles transported away from the surface of the article satisfies a particle criterion. In response to a determination that the number of particles transported away from the article does not satisfy the criterion, the purge cycle is re-initiated.

  • Patent number: 11735420
    Abstract: Methods of depositing a film selectively onto a first material relative to a second material are described. The substrate is pre-cleaned by heating the substrate to a first temperature, cleaning contaminants from the substrate and activating the first surface to promote formation of a self-assembled monolayer (SAM) on the first material. A SAM is formed on the first material by repeated cycles of SAM molecule exposure, heating and reactivation of the first material. A final exposure to the SAM molecules is performed prior to selectively depositing a film on the second material. Apparatus to perform the selective deposition are also described.

  • Patent number: 11515155
    Abstract: Methods of improved selectively for SAM-based selective depositions are described. Some of the methods include forming a SAM on a second surface and a carbonized layer on the first surface. The substrate is exposed to an oxygenating agent to remove the carbonized layer from the first surface, and a film is deposited on the first surface over the protected second surface. Some of the methods include overdosing a SAM molecule to form a SAM layer and SAM agglomerates, depositing a film, removing the agglomerates, reforming the SAM layer and redepositing the film.
