Title: Lead titanate system dielectric thin film
Inventor: IIJIMA TAKASHI
IPC: H01B3/00
Filed: 1994-08-11
Abstract: PURPOSE:To reduce lowering of a dielectric constant to improve a dielectric characteristic even for a thin film by substituting and solid-dissolving a specific metallic element at a ratio of 1-50% to a titanium atom into the titanium position of the crystal lattice of lead titanate. CONSTITUTION:A metallic element, wherein an ion radius is in a rate of 0.60-0.90Angstrom , is substitionally solid-dissolved at a rate of 1-50mol% to a titanium atom into the titanium position of a crystal lattice showing the perovskite crystal structure of a thin film having the basic composition of lead titanate of a film thickness of 1mum or less. When the ion radius deviates from this range, the substitution becomes impossible because of too large a difference between the ion radii of the metallic element and the titanium. Also, substitution quantity in this substitution is made 1-50mol% to the titanium. This is because effect obtained by the substitution can not be sufficiently displayed when the substituted quantity is less than 1mol, and the crystal structure of a perovskite single phase can not be shown to deposit a third phase in a crystal to lower a dielectric characteristic when the substituted quantity exceeds 50%.
