Pulsed laser deposition is a superior technique for the growth of high quality thin films (<EQ 1 micrometers ) of electronic ceramics and has satisfied many applications. To meet developing applications, there is a need for thick films (>= 1 micrometers ) of electronic ceramics. Two film qualities principally control the growth of thick films: the film surface morphology and film stress. The deposition parameters which affect these qualities include: film deposition rate, film-substrate lattice mismatch, film-substrate thermal coefficient of expansion mismatch, and film growth kinetics. Our results suggest that it will be difficult to fabricate thick ceramic films of suitable electronic quality by conventional physical vapor deposition techniques.
