A sintered body, a method of fabricating the sintered body, a semiconductor fabricating device, and a method of fabricating the semiconductor fabricating device, the sintered body including 50 mass % or more of Y.sub.5O.sub.4F.sub.7, wherein the sintered body has a relative density of 97.0% or more and a Vickers hardness of 2.4 GPa or more.

A green body for a 3D ceramic and/or metallic body is produced by providing a metal or a mixture of metals and/or a metalloid and/or a non-metal or mixtures thereof in form of at least one aqueous solutions, such as a metal nitrate solution; if more than one aqueous solutions are provided, they differ in composition and/or isotope concentration. One aqueous metal solution is mixed with a gelation fluid at a first temperature to suppress an internal gelation of the feed solution mixture prior to its ejection. The feed solution mixture is ejected by inkjet printing to the green body under construction. The ejected feed solution is heated mixture on the green body to a second temperature to fix it on the green body under construction. Several process steps are repeated according to a 3D production control model until a desired form of the green body is attained.
