Inventor: YAMANOBE TOMOMI
IPC: H01L21/768
Filed: 2000-09-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the problem in which when a Ti film is formed on an oxide electrode, the Ti film reacts with the oxide electrode, forming a TiOx film which is an insulator and may be the cause for defective contacts, and at the TiOx formation, it is expanded in thickness about twice the Ti film, reducing the adhesion between the Ti film and the conductive oxide electrode. SOLUTION: Contact holes to an upper and a lower electrode of a ferroelectric capacitor are formed, and then a TiN film 9 is formed by sputtering method. Thereafter, the TiN film 9 is removed completely by a lift-off method, except in the bottom parts of the contact holes, suppressing the formation of TiOx or the separation of the film on the oxide electrode. Since the bottom part of a contact hole 12 to a diffusion layer 2 is formed of laminated metal constituted of a Ti film 13 and an Al film 14, defective contacts of the contact hole 12 with a Si substrate 1 can be prevented.
