Abstract
A method for depositing a functional material on a substrate is disclosed. A plate having a first surface and a second surface is provided. A layer of light scattering material is applied onto the first surface of the plate, and a layer of reflective material is applied onto the second surface of the plate. After a group of wells has been formed on the second surface of the plate, a layer of light-absorbing material is applied on the second surface of the plate. Next, the wells are partially filled with a functional material. The plate is then irradiated with a pulse of light to heat the light-absorbing material between the bottom of the well and the functional material. This heats the gas in the ullage between the light absorbing material and the functional material to increase the pressure in gas to expel the functional material from the wells onto a receiving substrate.
