    摘要: Implementations disclosed describe a system including a light source, an optical sensor, and a processing device. The light source directs, during a first time, a probe light into a processing chamber through a window. The light source ceases, during a second time, directing the probe light into the processing chamber through the window. The optical sensor detects, during the first time, a first intensity of a first light. The first light includes a portion of the probe light reflected from the window and a light transmitted from an environment of the processing chamber through the window. The optical sensor detects, during the second time, a second intensity of a second light. The second light includes the light transmitted from the environment of the processing chamber through the window. The processing device determines, using the first intensity and the second intensity, a transmission coefficient of the window.

    摘要: Embodiments herein include void-free material depositions on a substrate (e.g., in a void-free trench-filled (VFTF) component) obtained using directional etching to remove predetermined portions of a seed layer covering the substrate. In several embodiments, directional etching followed by selective deposition can enable fill material (e.g., metal) patterning in tight spaces without any voids or seams. Void-free material depositions may be used in a variety of semiconductor devices, such as transistors, dual work function stacks, dynamic random-access memory (DRAM), non-volatile memory, and the like.

    摘要: Examples of the present technology include semiconductor processing methods that may include generating a plasma from a deposition precursor in a processing region of a semiconductor processing chamber. The plasma may be generated at a delivered power within a first period of time when plasma power is delivered from a power source operating at a first duty cycle. The methods may further include transitioning the power source from the first duty cycle to a second duty cycle after the first period of time. A layer may be deposited on a substrate in the processing region of the semiconductor processing chamber from the generated plasma. The layer, as deposited, may be characterized by a thickness of 50 Å or less. Exemplary deposition precursors may include one or more silicon-containing precursors, and an exemplary layer deposited on the substrate may include an amorphous silicon layer.

    摘要: A method includes receiving first sensor data associated with a first iteration of a first recipe operation of a substrate processing recipe. The method further includes determining disturbance data, the disturbance data being a difference between the first sensor data and first setpoint data of the first recipe operation. The method further includes determining, based at least in part on the disturbance data, a first actuation value associated with one or more components of a processing chamber. Actuation of the one or more components according to the first actuation value compensates for the disturbance data. The method further includes causing the actuation of the one or more components based on the first actuation value during a subsequent iteration of the first recipe operation of the substrate processing recipe to compensate for the disturbance data.

    摘要: Apparatus for processing substrates can include a gas distribution plate that includes an upper plate and a lower plate and a solid disk between the upper plate and the lower plate. Each of the upper plate and the lower plate has a central region and an outer region surrounding the central region, the central region being solid and the outer region having a plurality of through holes. The upper plate and the lower plate are coaxially aligned along a central axis extending through a center of the central region of the upper plate and a center of the central region of the lower plate. The solid disk is coaxially aligned with the upper plate and the lower plate. The solid disk is configured to block transmission of ultraviolet radiation through the solid disk.
