摘要:
[Object] To provide a deposition method that enables fine particles having a relatively large particle diameter (at least larger than 0.5 μm diameter) to be more stably deposited on a substrate by using a simple configuration.[Solving Means] In the deposition method, fine particles P whose surface is at least insulative are placed in an airtight container 2, and a carrier gas is introduced into the container, thereby triboelectrically charging the fine particles and generating an aerosol A of the fine particles. The fine particles in question are charged by friction with the inner surface of a transfer tubing 6 connected to the container, and the aerosol is conveyed via such tubing to a deposition chamber 3 which is maintained at a pressure lower than that in the airtight container. The charged fine particles are deposited on a substrate S placed in the deposition chamber.

A lithium or lithium alloy film forming method comprises: the step of heating and evaporating lithium or lithium alloy under an atmosphere of inert gas in an ultra fine particle producing chamber to produce ultra fine particles of lithium or lithium alloy therein; the step of transporting the ultra fine particles through a transfer pipe with the inert gas into a film forming chamber under vacuum atmosphere; the step of jetting the ultra fine particles onto a substrate arranged in the film forming chamber from a nozzle; the step of moving a substrate holder holding the substrate in the X-direction and/or Y-direction; the step of preheating the substrate at a predetermined temperature within the range of 100 to the melting point of lithium or lithium alloy: and the step of forming a film of lithium or lithium alloy on the substrate being moved with the substrate holder.

A deposition method is provided to enable fine particles having a relatively large particle diameter, for example, a diameter larger than 0.5 μm, to be stably deposited on a substrate. The fine particles with insulating surface are placed in an airtight container, and a carrier gas is introduced into the container, triboelectrically charging the fine particles and generating an aerosol of the fine particles. The fine particles are charged by friction with the inner surface of a transfer tubing connected to the container, and the aerosol is conveyed via such tubing to a deposition chamber that is maintained at a pressure lower than that in the airtight container. The charged fine particles are deposited on a substrate placed in the deposition chamber.
