Patent ID: 8648992

Claim:
A supporting body for use in a manufacturing method comprising the following steps: forming an insulation film ( 12 ) on a substrate ( 11 ); laminating an adhesion layer ( 15 ) onto the insulation film; forming a lower electrode ( 14 ) on the adhesion layer; dissolving an organic barium compound, an organic strontium compound and a titanium alkoxide in an organic solvent to achieve a molar ratio of Ba:Sr:Ti=1−x:x:y, coating the resulting thin film formation Ba 1−x Sr x Ti y O 3 composition onto a lower electrode and drying to thereby form a coating; forming a dielectric thin film ( 16 ) by calcining the substrate with the coating formed thereon; and forming an upper electrode ( 17 ) on the dielectric thin film, wherein the composition is coated onto the lower electrode without performing an annealing process at a temperature higher than 300° C. after forming the lower electrode; the drying temperature is within a range from ambient temperature to 500° C.; the calcining temperature is within a range of 500 to 800° C.; and the thickness of the dielectric thin film formed after the first calcining is 20 to 600 nm; the supporting body comprising: a substrate; an insulation film formed on the substrate; and a lower electrode formed through an adhesion layer on the insulating film, wherein, an average crystal grain size in the lower electrode is 100 nm or less; the lower electrode has a preferred orientation to the (111) face, (001) face or the (110) face; a residual stress of the lower electrode is −2000 to −100 MPa; and a lower electrode thickness is 50 to 600 nm.
