A novel heat-resistant low-silica zeolite, an industrial production process, and uses of the low-silica zeolite are provided. The heat-resistant low-silica zeolite contains Si and Al in a molar ratio of SiO.sub.2 /Al.sub.2 O.sub.3 ranging from 1.9 to 2.1, and has sodium and/or potassium as metal cation, wherein the low-silica zeolite contains low-silica faujasite type zeolite at a content of not lower than 88%, and has a thermal decomposition temperature ranging from 870.degree. C. to 900.degree. C. in the air. The process for producing the heat-resistant low-silica zeolite comprises mixing a solution containing an aluminate with another solution containing a silicate, allowing the resulting mixture to gel, and aging the resulting gel, at the temperature of from 0.degree. C. to 60.degree. C., to prepare a slurry having a viscosity ranging from 10 to 10000 cp and containing amorphous aluminosilicate having a specific surface area of not less than 10 m.sup.2 /g with an SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio ranging from 1.9 to 2.1; and subsequently crystallizing the aluminosilicate. The low-silica zeolite ion-exchanged with lithium or an alkaline earth metal is useful for gas separation.

A semiconductor device chip has a plurality of projecting electrodes mounted on a wiring board or wafer having electrodes respectively corresponding to the projecting electrodes of the semiconductor device chip. An insulator is applied to the front side of the semiconductor device wafer where the projecting electrodes are formed, to fill any spaces between adjacent electrodes with the insulator. The front side of the wafer covered with the insulator is planarized to expose the end surfaces of the projecting electrodes, and the wafer is divided along division lines to obtain a plurality of individual semiconductor device chips. Each chip is mounted on the wiring board or the wafer with an anisotropic conductor interposed between the projecting electrodes of each chip and the electrodes of the wiring board or the wafer to thereby respectively connect the projecting electrodes and the electrodes through the anisotropic conductor.
