Title: Manufacture of semiconductor device
Inventor: OYA KATSUHIKO
IPC: H01L21/768
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a lamination structure wiring by performing Cl gas treatment and F gas treatment for a lower wiring surface exposed in a bottom part of a connection hole and forming a metallic film inside a connection hole selectively. SOLUTION: An SiO2 film 3 is formed by thermally oxidizing an Si substrate 1 and a TiN film 5, an Al-Cu film 7 and a Tin film 9 are deposited thereon. The films are subjected to patterning and a lamination structure wiring 11 is formed. An SiO2 film 13 of a layer insulation film is deposited on the Si substrate 1 and a connection hole is formed. Thereafter, plasma treatment of Cl gas and F gas is carried out. The Si substrate 1 is carried to a W film formation chamber so as not to come into contact with the air for natural oxidation prevention and is subjected to heating and temperature rise. Then, a W film 27 is buried inside a connection hole 15 entirely. Therefore, even if alignment of a connection hole and a lower wiring is offset when a lower layer is the lamination structure wiring 11, metal can be buried in a connection hole stably.

Abstract: PURPOSE:To exhibit stable performance with less fluctuation in potential by providing the synergistic effect of the inactivation of the corona product by a nitrongenous heterocyclic compd. and the charge trap removal by arom. sulfonic acid compd. CONSTITUTION:The nitrogenous heterocyclic compd. contg. nitrogen in the conjugate structure of a ring and the arom. sulfonic acid compd. are introduced at the boundary of a photosensitive layer and a conductive base body. Since the electron density on this nitrogen atom is lower than in the case of on the ordinary nitrogen atom, the influence in the degradation in the sensitivity on the photosensitive layer and the influence of the increase in residual potential are lessened even if these compds. are interposed between the conductive substrate and the photosensitive layer. These compds. can be inactivated by forming complexes with acidic materials, etc., such as, corona products. The arom. sulfonic acid compd. is made to coexist in this nitrogen atom, by which the trapped charges are rapidly and effectively released. The stable performance with the less fluctuation in the potential is exhibited by the synergistic effect thereof.
