摘要:
Some embodiments include a memory device and a method of forming the memory device. One such memory device includes a string of stacked memory cells. Each of the memory cells in the string includes a charge storage structure and a recessed control gate. The recessed control gate has a substantially smooth surface separated from the charge storage structure by dielectric material. One such method includes etching heavily boron doped polysilicon selective to oxide to form a recessed control gate having a surface with nubs. A smoothing solution is applied to the surface of the recessed control gate to smoothen the nubs. Additional apparatuses and methods are described.

Some embodiments include methods of treating semiconductor substrates. The substrates may be exposed to one or more conditions that vary continuously. The conditions may include temperature gradients, concentration gradients of one or more compositions that quench etchant, pH gradients to assist in removing particles, and/or concentration gradients of one or more compositions that assist in removing particles. The continuously varying conditions may be imparted by placing the semiconductor substrates in a bath of flowing rinsing solution, with the bath having at least two feed lines that provide the rinsing solution therein. One of the feed lines may be at a first condition, and the other may be at a second condition that is different from the first condition. The relative amount of rinsing solution provided to the bath by each feed line may be varied to continuously vary the condition within the bath.

The invention includes semiconductor processing methods, including methods of forming capacitors. In one implementation, a semiconductor processing method includes providing a semiconductor substrate comprising a layer comprising at least one metal in elemental or metal alloy form. The metal comprises an element selected from the group consisting of platinum, ruthenium, rhodium, palladium, iridium, and mixtures thereof. At least a portion of the layer is etched in a halogenide, ozone and H2O comprising ambient.
摘要:
A fuel pump module including a fuel reservoir, a fuel pump communicating with the fuel reservoir and having a fuel outlet, and a fuel filter assembly movably coupled to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank. The fuel filter assembly communicates with the fuel outlet to filter fuel that has passed through the fuel pump. In one aspect of the invention, the fuel filter assembly is pivotally movable with respect to the reservoir. In another aspect of the invention, the fuel filter assembly is linearly movable with respect to the reservoir.
