Abstract

The dielectric properties of Ba 0.65Sr 0.35TiO 3(BST) films deposited by an electron beam assisted ionized cluster beam epitaxy (ICBE) technique were investigated. Highly (110) oriented BST films having a thickness up to 1 μm have been successfully grown on a Si (100) substrate at 400 °C using the electron beam assisted ICBE system with a plasma O 2 source. It was found that the dielectric constant increases from 475 to 1191 with different process conditions. A BST film with a thickness of 500 angstroms deposited at a substrate temperature of 400 °C has a dielectric constant of 1191 and a leakage current of about 2.37×10 -9 A/cm 2. This shows the BST film can be applied to dielectrics of ULSI capacitors.
