The deposition apparatus includes a chamber including a deposition space, a stage that supports a substrate, a light source, a gas supply, and a heater. The light source includes an emission source that emits an energy ray and is disposed to face the deposition space. The gas supply includes a shower plate and a gas diffusion space. The shower plate includes a first surface that faces the light source, a second surface that faces the stage, and a plurality of through-holes that penetrates the first surface and the second surface, the shower plate allowing the energy ray to transmit therethrough. The gas diffusion space faces the first surface and diffuses raw material gas including an energy ray-curable resin that cures when the energy ray-curable resin is irradiated with the energy ray. The gas supply supplies the raw material gas into the deposition space from the gas diffusion space. The heater heats the first surface of the shower plate.

A substrate surface planarization method includes an arranging step of arranging a liquid curable composition onto a substrate surface having unevenness, a waiting step of waiting until the surface of the layer of the liquid curable composition becomes smooth, and a light exposure step of applying light to cure the layer of the liquid curable composition in this order.
