Patterning for selective ejections of printable ammonium-based chalcogenometalate fluids

A printing device, comprising:

• a pen to eject:
• a patterning material on a substrate to define an area within to eject a first printable ammonium-based chalcogenometalate fluid;
• and
• an amount of a printable ammonium-based chalcogenometalate fluid, the pen comprising:
• a firing chamber to hold the amount of printable ammonium-based chalcogenometalate fluid;
• an orifice;
• and
• an ejector to eject the amount of printable ammonium-based chalcogenometalate fluid through the orifice;
• a reservoir to supply the printable ammonium-based chalcogenometalate fluid and patterning material to the pen;
• and
• a patterning material curing device to selectively cure the patterning material.

A method of forming a semiconductor device, comprising:

• selectively depositing a patterning material on a substrate to form an area into which a printable ammonium-based chalcogenometalate fluid may be restrained;
• curing the patterning material;
• depositing the printable ammonium-based chalcogenometalate fluid;
• heating the layer of first printable ammonium-based chalcogenometalate fluid to dissipate the first printable ammonium-based chalcogenometalate fluid into a transition metal dichalcogenide having the form MX2 with the first dopant distributed therethrough;
• and
• removing the patterning material from the substrate.
