Abstract:
1. A method of forming an organic film, comprising: providing an evaporation apparatus, the evaporation apparatus comprising: a gas storage chamber; a first evaporator, connected with the gas storage chamber through a first pipe, wherein the first pipe has a first valve; a pressure gauge, connected with the gas storage chamber through a second pipe; a pyrolysis chamber, connected with the gas storage chamber through a third pipe, wherein the third pipe has a second valve, wherein the first evaporator is connected with the pyrolysis chamber through the gas storage chamber, and the gas storage chamber is disposed between the first evaporator and the pyrolysis chamber; and a deposition chamber, connected with the pyrolysis chamber through a fourth pipe; placing a first organic material in the first evaporator, and turning off the second valve and turning on the first valve; performing a first evaporation process to the first organic material in the first evaporator, so as to form a first organic gas, wherein the first organic gas is passed into the gas storage chamber through the first pipe and stored in the gas storage chamber; when a pressure of the first organic gas stored in the gas storage chamber reaches a predetermined value, that is, the amount of the first organic gas is equal to a specific value, turning off the first valve and turning on the second valve for passing the first organic gas into the pyrolysis chamber through the third pipe; pyrolyzing the first organic gas in the pyrolysis chamber to form a first organic monomer; and delivering the first organic monomer to the deposition chamber through the fourth pipe for deposition, so as to form a first organic film.
