Mask forming methods and a field emission display emitter mask forming method

A mask forming method comprising:

• forming a masking layer over a surface of a substrate;
• screen printing plural masking particles over a surface of the masking layer;
• and
• removing at least portions of the masking layer using the masking particles as a mask.

A mask forming method comprising:

• forming a masking layer over a surface of a substrate;
• forming a solution layer comprising a liquid medium and a plurality of masking particles over a surface of the masking layer and providing the masking particles over predefined regions of the substrate during the forming the solution layer;
• removing at least portions of the masking layer using the masking particles as a mask;
• and
• wherein the providing comprises printing the masking particles using a screen.

A mask forming method comprising:

• forming a masking layer over a surface of a substrate;
• forming a layer of solution including plural masking particles over a surface of the masking layer;
• guiding the masking particles to predefined regions over the substrate using a screen;
• and
• removing at least portions of the masking layer using the masking particles as a mask.

A field emission display emitter mask forming method comprising:

• forming a masking layer over a surface of an emitter substrate;
• printing a layer of masking particles over a surface of the masking layer using a screen and a squeegee;
• removing portions of the masking layer intermediate the screen printed masking particles;
• and
• removing the masking particles from remaining portions of the masking layer following the removing of portions of the masking layer.

A mask forming method comprising:

• forming a masking layer over a surface of a substrate;
• forming a solution layer comprising a liquid medium and a plurality of masking particles over a surface of the masking layer and providing the masking particles over predefined regions of the substrate during the forming the solution layer;
• removing at least portions of the masking layer using the masking particles as a mask;
• and
• wherein the providing comprises screen printing masking particles within a solution containing photoresist.

A mask forming method comprising:

• forming a masking layer over a surface of a substrate;
• forming a solution layer comprising a liquid medium and a plurality of masking particles over a surface of the masking layer and providing the masking particles over predefined regions of the substrate during the forming the solution layer;
• removing at least portions of the masking layer using the masking particles as a mask;
• and
• selecting the predefined regions of the substrate before the forming the solution layer.
