Abstract: A method for the fabrication of a cap layer on a top electrode layer of a ferroelectric capacitor includes the steps of depositing an amorphous layer, usually made of Sr(x)Ru(y)O3, on the top electrode and then annealing the amorphous layer in two stages in order convert the amorphous layer into the cap layer. The first anneal is performed at 500° C. to 700° C. in a non-oxidizing atmosphere, such as nitrogen, and converts the amorphous layer into a crystallized layer of Sr(x)Ru(y)O3. The second anneal is performed at 300° C. to 500° C. in an oxidizing atmosphere, such as oxygen, and converts the crystallized layer into the cap layer. The method is applied to the formation of a ferroelectric capacitor element of an integrated semiconductor device.

Abstract: A method of generating a solid-shell object from a solid object having a shelling-designated surface and other surfaces includes the steps of inwardly displacing the other surfaces to generate displaced surfaces, dividing the shelling-designated surface and the displaced surfaces into portions, removing unnecessary portions among the portions to leave necessary portions of the shelling-designated surface and the displaced surfaces, and connecting the necessary portions of the shelling-designated surface and the displaced surfaces together to generate a first surface model. The method further includes the steps of removing the shelling-designated surface from the solid object to generate a second surface model, and connecting the first surface model and the second surface model to generate the solid-shell object.

Abstract: A multilayered electronic part with minimized silver diffusion into ceramic body. The multilayered electronic part is produced by sintering a green ceramic body of a plurality of ceramic layers comprising a main phase and a grain boundary phase, at least one of the ceramic layers being printed thereon Ag-containing internal electrode patterns which may serve as markers for indicating several information such as a production number, a name of manufacturer, a kind of circuit, etc. By the production method of the invention, the diffusion of Ag in the internal electrode patterns into the ceramic body is effectively prevented to avoid the deterioration of the electrical characteristics as well as to avoid the blackening of the ceramic to ensure a high lightness of the ceramic body which enhances the reliability of the visual identification and distinguishability of the markers.

Abstract: An on-line information providing scheme capable of dynamically accounting for user's interest with respect to information and providing appropriate information presentation according to the user's interest. An information provider device updates the information attribute value of the specified information and a user attribute value of the user by reflecting the information attribute value and the user attribute value with each other so as to dynamically update the user's interest and an information characteristic of the specified information, and selects a first set of information according to the user's interest by matching an updated user attribute value with the information attribute value of each information, and a second set of information according to the user's interest by matching an updated information attribute value of the specified information with the information attribute value of each other information.
