摘要： A composition for forming a metal oxide thin film pattern which is a solution containing one or more hydrolytic metal compounds selected from the group consisting of hydrolytic organometallic compounds (e.g., metal alkoxide) and metal halides, and a water generating agent which frees water under the effect of irradiation with active rays (e.g., o-nitrobenzyl alcohol and 2-nitroethanol) and, as required, an acid generating agent which frees acid under the effect of irradiation with active rays is disclosed. A thin film pattern is formed by coating the composition onto a substrate, irradiating active rays for forming an image on the resultant photosensitive coating film, developing the same with water or an alcoholic solvent to remove the non-exposed portion, and heat-treating the substrate to convert the remaining film into a metal oxide, thereby forming a negative-type metal oxide thin film pattern.

The resultant film is exposed to active rays in compliance with a prescribed pattern to form an image and developed with a solvent to remove non-exposed portions, and then the remaining exposed portions are subjected to a heat treatment to convert the exposed portions into a dielectric substance comprising a metal oxide as expressed by the following formula (I):(Bi.sub.2 O.sub.2).sup.2+ (A.sub.m-1 B.sub.m O.sub.3m+1).sup.2-(I)where A is one or more elements selected from the group consisting of Ba, Sr, Pb and Bi; B is one or more elements selected from the group consisting of Ti, Nb and Ta; and m is an integer of from 2 to 5.

摘要： A composition for formation of thin-film patterns of a metal oxide which comprises a metal alkoxide and one or more nitro compounds selected from the group consisting of nitrobenzyl alcohol derivatives, nitrobenzaldehyde derivatives, nitrostyrol derivatives, nitroacetophenone derivatives, nitroanisole derivatives and nitrofuran derivatives. This composition is applied to a substrate which is then irradiated with light to perform patterning by utilizing the difference in solubility between the light-irradiated portion and the non-light-irradiated portion, attributed to the photodecomposition reaction of the irradiated portion. A photoreactive compound is added to a starting solution which contains an organic solvent and an organic metal compound, the solution is misted, and the resulting mist is deposited on a substrate while irradiating with light.

摘要： The organozirconium composite of the present invention has a decomposition temperature which is near the respective decomposition temperatures of an organolead compound and an organotitanium compound. The raw material solution can precisely control the composition of a PZT thin film over a broad temperature range. The raw material solution is less likely to react an organolead compound even when mixed with the organolead compound. The present invention provides a raw material solution which is less likely to cause vapor phase cracking. The organozirconium composite comprises one, or at least two kinds of zirconium chelate complexes containing, as a ligand, both of a first β diketone and a second β diketone having a structure different from that of the first β diketone, wherein, when at least two kinds of zirconium chelate complexes are contained, the coordination numbers of the first β diketone and the second β diketone that coordinate to at least two kinds of zirconium chelate complexes vary depending on the respective zirconium chelate complexes.

摘要： A first photosensitive liquid solution is applied to a substrate, patterned through exposure to radiation and development, and annealed to form a desired solid material, such as SrBi.sub.2 Ta.sub.2 O.sub.9, that is incorporated into a component of an integrated circuit Fabrication processes are designed protect the self-patterned solid material from conventional IC processing and to protect the conventional materials, such as silicon, from elements in the self-patterned solid material. In one embodiment, a layer of bismuth oxide is formed on the SrBi.sub.2 Ta.sub.2 O.sub.9 and a silicon oxide hole is etched to the bismuth oxide. The bismuth oxide protects the SrBi.sub.2 Ta.sub.2 O.sub.9 from the etchant, and is reduced by the etchant to bismuth. Any remaining bismuth oxide and much of the bismuth are vaporized in the anneal, and the remaining bismuth is incorporated into the SrBi.sub.2 Ta.sub.2 O.sub.9.
