Abstract: Some embodiments include an integrated assembly having a source structure, and having a stack of alternating conductive levels and insulative levels over the source structure. Cell-material-pillars pass through the stack. The cell-material-pillars are arranged within a configuration which includes a first memory-block-region and a second memory-block-region. The cell-material-pillars include channel material which is electrically coupled with the source structure. Memory cells are along the conductive levels and include regions of the cell-material-pillars. A panel is between the first and second memory-block-regions. The panel has a first material configured as a container shape. The container shape defines opposing sides and a bottom of a cavity. The panel has a second material within the cavity. The second material is compositionally different from the first material. Some embodiments include methods of forming integrated assemblies.

Abstract: A method is provided for in-situ monitoring of etch uniformity during plasma etching, on the basis of the detection of interferometry patterns. The method is applicable to a reactor wherein a plasma is created in the area between the surface to be etched and a counter-surface arranged essentially parallel to the surface to be etched. The occurrence of interference patterns is detected at a location that is placed laterally with respect to the area between the surface to be etched and the counter-surface. The presence of an interference pattern at a particular wavelength is observed through the detection of oscillations of the light intensity measured by an optical detector, preferably by the standard Optical Emission Spectrometry tool of the reactor. When these oscillations are no longer detectable, non-uniformity exceeds a pre-defined limit. The counter surface is arranged such that the oscillations are detected.

Abstract: Device and method for monitoring a plasma in a chamber of a plasma reactor is are disclosed. In one aspect, the method includes measuring plasma parameter data at a surface of a single planar Langmuir probe in contact with the plasma. A biasing capacitor is connected between the single planar Langmuir probe and a DC-bias source. Subsequently a discharge current of the biasing capacitor as a result of the DC-bias is measured, and a probe potential at the single probe during the discharge is measured. The measurements can be used to detect presence and/or thickness of a dielectric film on the probe surface.
