    摘要： An electrochemical device for separating oxygen from an oxygen-containing gas comprises a plurality of planar ion-conductive solid electrolyte plates and electrically-conductive gas-impermeable interconnects assembled in a multi-cell stack. Electrically-conductive anode and cathode material is applied to opposite sides of each electrolyte plate. A gas-tight anode seal is bonded between the anode side of each electrolyte plate and the anode side of the adjacent interconnect. A regulating electrode, applied to the anode side of each electrolyte plate between the anode seal and the edge of the anode, eliminates anode seal failure by maintaining the 24-hour anode seal power density below about 1.5 .mu.W/cm.sup.2. A gas-tight seal is applied between the cathode sides of each electrolyte plate and the adjacent interconnect such that the anode and cathode seals are radially offset on opposite sides of the plate. The combination of regulating electrodes and offset seals is particularly effective in eliminating anode seal failure.

    摘要： A chemical mechanical polishing composition contains 1) water, 2) optionally an abrasive material, 3) an oxidizer, preferably a per-type oxidizer, 4) a small amount of soluble metal-ion oxidizer/polishing accelerator, a metal-ion polishing accelerator bound to particles such as to abrasive particles, or both; and 5) at least one of the group selected from a) a small amount of a chelator, b) a small amount of a dihydroxy enolic compound, and c) a small amount of an organic accelerator. Ascorbic acid in an amount less than 800 ppm, preferably between about 100 ppm and 500 ppm, is the preferred dihydroxy enolic compound. The polishing compositions and processes are useful for substantially all metals and metallic compounds found in integrated circuits, but is particularly useful for tungsten. The present invention also pertains to surface-modified colloidal abrasive polishing compositions and associated methods of using these compositions, particularly for chemical mechanical planarization, wherein the slurry comprises low levels of chelating free radical quenchers, non-chelating free radical quenchers, or both.
