A silicon-based electrode forms an interface with a layer pair being: 1. a thin, semi-dielectric layer made of a lithium (Li) compound, e.g. lithium fluoride, LiF, disposed on and adheres to the electrode surface of the silicon-based electrode and 2. an molten-ion conductive layer of a lithium containing salt (lithium salt layer) disposed on the semi-dielectric layer. One or more device layers can be disposed on the layer pair to make devices such as energy storage devices, like batteries. The interface has a low resistivity that reduces the energy losses and generated heat of the devices.

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.

A method for manufacturing a semiconductor device is provided. In the method, a silicon-containing gas is supplied to a substrate having a recess in a surface thereof at a predetermined film deposition temperature, thereby depositing a first silicon film in the recess. Chlorine and hydrogen are supplied to the substrate while maintaining the predetermined film deposition temperature, thereby etching the first silicon film deposited in the recess to expand an opening width of the first silicon film. The silicon-containing gas is supplied to the substrate while maintaining the predetermined film deposition temperature, thereby further depositing a second silicon film on the first silicon film in the recess.
