The radicals in the plasma are fed to the treatment chamber via radical-passing holes (111) of a plasma-confinement electrode plate (110) for plasma separation, the treatment gas is fed to the treatment chamber (121) to be mixed with the radicals in the treatment chamber, and then the substrate surface is cleaned by the mixed atmosphere of the radicals and the treatment gas.

  • Patent number: 10084882
    Abstract: The invention relates to a server and a method for processing requests when several requests compete within the same connection having fixed resources. Conventionally, a priority scheme provides priority values for a priority parameter that express priorities relatively to the priorities of other requests, meaning that a relative allocation of resources is obtained for each request. To achieve a better control on the server by the client, the invention provides specific possible values for the priority parameter that correspond to respective processing profiles. Each processing profile represents specific server behavior for resources allocation, by defining a predefined amount of resources. Thus, the client may choose between using the specific possible values to control the exact amount of resources that will be allocated by the server to process some specific requests, and using the other possible values that correspond to a relative allocation of resources as already done in known techniques.

  • Patent number: 10079152
    Abstract: A method used to create small pattern features over existing topography variations. The method includes providing a substrate having a surface having non-planar surface variations; forming a multi-stack layer over the substrate, by applying a first carbon layer over the substrate, with the resultant first carbon layer having non-planar surface variations corresponding to the non-planar surface variations of the underlying substrate, followed by applying a second planarizing layer over the first carbon layer; depositing a hard mask on the multi-stack layer; forming a patterned layer on the hard mask, the formed patterned layers having features; and performing one or more etch steps to etch the formed patterned layer features into the multi-layer stack. The multi-layer stack has a composite effective mechanical stiffness (Eeff) sufficient to maintain the one or more etched features with minimal feature collapse.
