  • Publication number: 20190287795
    Abstract: Techniques herein include processes and systems by which a reproducible CD variation pattern can be mitigated or corrected to yield desirable CDs from microfabrication patterning processes, via resolution enhancement. A repeatable portion of CD variation across a set of wafers is identified, and then a correction exposure pattern is generated. A direct-write projection system exposes this correction pattern on a substrate as a component exposure, augmentation exposure, or partial exposure. A conventional mask-based photolithographic system executes a primary patterning exposure as a second or main component exposure. The two component exposures when combined enhance resolution of the patterning exposure to improve CDs on the substrate being processed without measure each wafer.

  • Patent number: 10151981
    Abstract: Some embodiments include methods of forming structures supported by semiconductor substrates. Radiation-imageable material may be formed over a substrate and patterned into at least two separated features. A second material may be formed over the features and across one or more gaps between the features. At least one substance may be released from the features and utilized to alter a portion of the second material. The altered portion of the second material may be selectively removed relative to another portion of the second material which is not altered. Also, the features of radiation-imageable material may be selectively removed relative to the altered portion of the second material. The second material may contain one or more inorganic components dispersed in an organic composition. The substance released from the features of radiation-imageable material may be acid which forms cross-links within such organic composition, an hydroxyl, or any other suitable substance.

  • Publication number: 20180342410
    Abstract: Disclosed herein is a technology related to the amelioration (e.g., correction) of global wafer distortion based on a determination of localized distortions of a semiconductor wafer. Herein, a distortion is either an out-of-plane distortion (OPD) or in-plane distortion (IPD). The reference plane for this distortion is based on the plane shared by the surface of a presumptively flat semiconductor wafer. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Publication number: 20180333680
    Abstract: A process is disclosed for wetting a filter cartridge used to treat a liquid solvent used in semiconductor manufacture. In the process, a filter cartridge having void spaces wherein the void spaces contain residual gas from the manufacturing process used to make the filter cartridge is connected to a source of purging gas. The purging gas is flowed through the filter cartridge to at least partially displace at least a portion of the residual gas from the manufacturing process used to make the filter cartridge. Next, liquid solvent is pumped through the filter cartridge so that the purging gas dissolves into the liquid solvent and to at least partially fill the void spaces to thereby at least partially wet out the filter cartridge with the liquid solvent.

  • Patent number: 9718082
    Abstract: A fluid dispensing apparatus is disclosed. Systems include an in-line or linear bladder apparatus configured to expand to collect a charge of fluid, and contract to assist with fluid delivery and dispensing. During a dispense-off period process fluid can collect in this bladder after the process fluid is pushed through a fine filter (micro filter). A given filtration rate can be less than a dispense rate and thus the system herein compensates for filter-lag that often accompanies fluid filtering for microfabrication, while providing a generally linear configuration that reduces chances for defect creation.

  • Patent number: 9653315
    Abstract: A method of fabricating a substrate includes forming spaced first features over a substrate. An alterable material is deposited over the spaced first features and the alterable material is altered with material from the spaced first features to form altered material on sidewalls of the spaced first features. A first material is deposited over the altered material, and is of some different composition from that of the altered material. The first material is etched to expose the altered material and spaced second features comprising the first material are formed on sidewalls of the altered material. Then, the altered material is etched from between the spaced second features and the spaced first features. The substrate is processed through a mask pattern comprising the spaced first features and the spaced second features. Other embodiments are disclosed.
