Patent number: 8647737Abstract: The invention provides a process for forming crack-free dielectric films on a substrate. The process comprise the application of a dielectric precursor layer of a thickness from about 0.3 ?m to about 1.0 ?m to a substrate. The deposition is followed by low temperature heat pretreatment, prepyrolysis, pyrolysis and crystallization step for each layer. The deposition, heat pretreatment, prepyrolysis, pyrolysis and crystallization are repeated until the dielectric film forms an overall thickness of from about 1.5 ?m to about 20.0 ?m and providing a final crystallization treatment to form a thick dielectric film. Also provided was a thick crack-free dielectric film on a substrate, the dielectric forming a dense thick crack-free dielectric having an overall dielectric thickness of from about 1.5 ?m to about 20.0 ?m.Type: GrantFiled: September 30, 2011Date of Patent: February 11, 2014Assignee: UChicago Argonne, LLCInventors: Beihai Ma, Uthamalingam Balachandran, Sheng Chao, Shanshan Liu, Manoj Narayanan
