A method for the joining of ceramic pieces with a hermetically sealed joint comprising brazing a layer of joining material between the two pieces. The ceramic pieces may be aluminum nitride or other ceramics, and the pieces may be brazed with a high purity silicon or a silicon alloy under controlled atmosphere. The joint material is adapted to later withstand both the environments within a process chamber during substrate processing, and the oxygenated atmosphere which may be seen within the interior of a heater or electrostatic chuck.

Embodiments of the invention generally relate to solid state battery structures, such as Li-ion batteries, methods of fabrication and tools for fabricating the batteries. One or more electrodes and the separator may each be cast using a green tape approach wherein a mixture of active material, conductive additive, polymer binder and/or solid electrolyte are molded or extruded in a roll to roll or segmented sheet/disk process to make green tape, green disks or green sheets.

A method of making a ceramic composite comprises forming a wet ceramic composition comprising a plurality of discrete ceramic components and a fluxing agent dissolved in a solvent. At least a portion of the solvent is removed from the wet ceramic composition to form a dried ceramic composition comprising the plurality of discrete ceramic components coated with the fluxing agent. The dried ceramic composition is sintered to form the ceramic composite, the sintering being carried out at a sinter temperature sufficient to fuse the discrete ceramic components at bridging sites formed where two or more of the discrete ceramic components coated with fluxing agent are in physical contact.
