Abstract: <P>PROBLEM TO BE SOLVED: To prevent deterioration of ferroelectric characteristics due to a crack and a void, and residual stress of a ferroelectric thin film, in a capacitive element with the ferroelectric thin film as a capacitive insulation film.  <P>SOLUTION: The capacitive element comprising a lower electrode 107, the capacitive insulation film 109a and an upper electrode 110a formed on a substrate 101 in this order from the lower side, is formed. The periphery of the lower electrode 107 is covered with an inter-layer insulation film 108 whose top surface is lower than that of the lower electrode 107, so that a step is formed between the lower electrode 107 and the inter-layer insulation film 108. The capacitive insulation film 109a is formed extending over the lower electrode 107 to the inter-layer insulation film 108. A hollow 111 is formed at the step part of the periphery of the lower electrode 107. Thanks to the hollow 111, distortion in the part where different kinds of films contact to each other is relaxed. Thereby deterioration of the ferroelectric characteristics due to generation of the crack and the void, and the residual stress of the ferroelectric thin film acting as the capacitive insulation film 109a is prevented.  <P>COPYRIGHT: (C)2004,JPO
