  • Publication number: 20220326607
    Abstract: Methods and apparatus leverage dielectric barrier discharge (DBD) plasma to treat samples for surface modification prior to photomask application and for photomask cleaning. In some embodiments, a method of treating a surface with AP plasma includes igniting plasma over an ignition plate where the AP plasma is formed by one or more plasma heads of an AP plasma reactor positioned above the ignition plate, monitoring characteristics of the AP plasma with an optical emission spectrometer (OES) sensor to determine if stable AP plasma is obtained and, if so, moving the AP reactor over a central opening of an assistant plate where the central opening contains a sample under treatment and where the assistant plate reduces AP plasma arcing on the sample during treatment. The AP reactor scans back and forth over the central opening of the assistant plate while maintaining stabilized AP plasma to treat the sample.

  • Publication number: 20080213978
    Abstract: The present invention discloses methods and apparatuses for substrate singulation. Embodiments of the present invention comprise cryogenic-assist scribing or cutting mechanism for debris reduction, preferably cryogenic-assist laser scribe or cutting; controlling mechanism for debris flow and redeposition during laser process; and integrated, dry debris removal scribing process with breaking mechanism. An exemplary embodiment comprises an integrated housing for aligning a laser beam with the cryogenic cleaning beam. The integrated housing is preferably made of low thermal conductivity material to provide a high temperature gradient between the low temperature of the cryogenic fluid and the ambient temperature, preventing condensation of the moisture. The entire areas, or the critical areas of the apparatus can also be purged with flowing “dry” inert gases to further reduce the condensation moisture. Reactive gas can be introduced to react with debris, converting into gaseous form for ease of removal.

  • Patent number: 7040961
    Abstract: A plasma assisted cryogenic cleaner for and a method of performing cleaning of a surface that must be substantially free of contaminants has a resiliently mounted nozzle for spraying a cryogenic cleaning medium on the surface. The cleaning is conducted by applying to the substrate surface a mixture of gases selected from the group consisting of oxygen, nitrogen, hydrogen, fluorine, hydrofluorocarbon or a mixture of such gases to both remove the photoresist layer and alter the composition of the residues such that the residues are soluble in water and/or have a weakened bonds that they can be removed with a stream of cryogenic medium. The cryogenic and plasma processes can be performed sequentially or simultaneously.

  • Patent number: 6945853
    Abstract: A cryogenic cleaner for and a method of performing cleaning of a surface that must be substantially free of contaminants utilizing a multi-stage, multi-mode filtered carbon dioxide-containing cleaning medium. Multiple stages and multiple types of filtration/purification are provided to remove contaminants such as hydrocarbons from the medium. In accordance with preferred embodiments, a filtering/purification process is provided that desirably utilizes one or more of: condensation of the hydrocarbon; particulate filtration; chemical filtration using activated filters; and catalytic oxidation. In certain embodiments, a resiliently mounted nozzle is provided for spraying a cryogenic cleaning medium on the surface. The nozzle may be driven in an oscillatory manner at a predetermined amplitude and frequency so the nozzle spray is delivered in a manner to provide pulsing of the spray and to provide as “snow plow” effect on contaminants as the spray delivers the cleaning medium against the surface.
