What are the ways to make thin film?5 answersThere are several methods for making thin films. One method involves using atomic layer deposition (ALD) and atomic layer etching (ALE) processes. In this method, a first thin film is formed through ALD, and then etched to a predetermined thickness using ALE to create a second thin film with a reduced thickness. Another method involves a thin film forming process that includes supplying a source gas, purging the gas, supplying a reactive gas, supplying plasma, and purging the reactive gas. During these operations, the source gas is bypassed to the exhaust unit at a reduced flow rate, resulting in reduced gas consumption and minimized generation of reaction by-products. Additionally, a thin film can be manufactured by forming an ink droplet on a substrate, evenly distributing the solvent in the droplet, and evaporating the solvent to form the thin film. Another method involves dispensing a solution on a substrate, spreading it into a thin layer using a hydrophilic material, and either allowing a thin film to grow through chemical reaction or evaporating the solution to leave behind a particulate film. Finally, a method includes introducing an organic metal gas containing hydrogen onto a substrate, introducing an oxidizing or nitriding gas, generating plasma, detecting emission intensity, and stopping plasma generation based on the detected intensity.
