Abstract: This application provides a three-dimensional porous material, a negative electrode composite material, and an application. The three-dimensional porous material has specially designed opening diameter distribution, a volume proportion of a hole whose opening diameter is less than or equal to 2 nm is greater than or equal to 70%, and a volume proportion of a hole whose opening diameter is 1 nm to 2 nm is greater than or equal to 50%. A proportion of an effective deposition hole in the three-dimensional porous material is high, and concentration of the opening diameter distribution is high. This can achieve good threshold limiting effect, to provide a negative electrode composite material having both a high specific capacity and high structural stability.

Abstract: Exemplary processing methods may include providing a silicon-containing precursor and a carbon-containing precursor to a processing region of a semiconductor processing chamber. A substrate may be housed in the processing region. The substrate may define a feature within the substrate. The methods may include forming plasma effluents of the silicon-containing precursor and the carbon-containing precursor. The methods may include depositing a silicon-and-carbon-containing material on the substrate. The methods may include providing a hydrogen-containing precursor to the processing region of the semiconductor processing chamber, forming plasma effluents of the hydrogen-containing precursor, and etching the silicon-and-carbon-containing material from a sidewall of the feature within the substrate.

Abstract: In semiconductor processing. plasma etching of materials (e.g., of carbon or silicon) to form vertical high aspect ratio recessed features can lead to clogging inside the recessed features due to unwanted deposition of a mask-derived clogging material (e.g., silicon oxide). This is addressed by declogging, which includes etching the clogging material preferably in the same process chamber by contacting the substrate with a halogen source. After the declogging step, plasma etching proceeds further. The declogging and plasma etching steps can be repeated as many times as needed to etch a recessed feature of desired depth.
