Abstract: Provided are a storage device, system, and method for throttling host writes in a host buffer to a storage device. The storage device is coupled to a host system having a host buffer that includes reads and writes to pages of the storage device. Garbage collection consolidates valid data from pages in the storage device to fewer pages. A determination is made as to whether a processing measurement at the storage device satisfies a threshold. A timer value is set to a positive value in response to determining that the processing measurement satisfies the threshold. The timer is started to run for the timer value. Writes from the host buffer are blocked while the timer is running. Writes remain in the host buffer while the timer is running. A write is accepted from the host buffer to process in response to expiration of the timer.

Abstract: This disclosure discusses cleaning of semiconductor wafers after the Chemical-Mechanical Planarization (CMP) of the wafer during the manufacturing of semiconductor devices. Disclosed is an alkaline chemistry for the post-CMP cleaning of wafers containing metal, particularly copper, interconnects. Residual slurry particles, particularly copper or other metal particles, are removed from the wafer surface without significantly etching the metal, leaving deposits on the surface, or imparting significant contamination to the wafer while also protecting the metal from oxidation and corrosion. Additionally, at least one strong chelating agent is present to complex metal ions in solution, facilitating the removal of metal from the dielectric and preventing re-deposition onto the wafer.

Abstract: This disclosure discusses cleaning of semiconductor wafers after the Chemical-Mechanical Planarization (CMP) of the wafer during the manufacturing of semiconductor devices.

Additionally, at least one strong chelating agent is present to complex metal ions in solution, facilitating the removal of metal from the dielectric and preventing re-deposition onto the wafer. Using acidic chemistry, it is possible to match the pH of the cleaning solution used after CMP to that of the last slurry used on the wafer surface.

Abstract: Provided are methods and systems for controlling the concentration of a component in a composition, and semiconductor processing methods and systems. One exemplary method of controlling the concentration of a component in a composition involves: providing a composition which has a liquid portion, wherein the liquid portion contains a component to be monitored; performing an absorption spectroscopy measurement on a sample of the composition; and controlling the concentration of the component in the composition based on the absorption spectroscopy measurement using a feedback control loop. The invention allows for controlling the concentration of a component in a composition, for example, a corrosion inhibitor in a chemical planarization (CMP) chemical, as well as in pre- and post-CMP storage/treatment chemicals, and can provide real time, accurate process control in a simple and robust manner.
