This paper has made an analysis of the generation and state ofstress during fabricating a multilayer composite cofired system，which indicates that the thermodynamic mismatch of the two thick films is the causes of interfacial stress．A discussion about the stress state and the influencing factors in the different stages for preparing composite cofired ceramic devices has been made by using a restrained two-layer stress model．This includes some processing measurements for improving interfacial stress and defects．Moreover，some influences of interfacial thermal stresses on the microstructures of composite multilayer systems have also been studied．
