Fabrication of electron-emitting device having ladder-like emitter electrode

A method comprising the steps of:

• forming a group of radiation-blocking features over a plurality of laterally separated radiation-blocking segments through each of which a line of segment openings extend;
• forming a primary layer of actinic material over the segments and features;
• backside exposing material of the primary layer not shadowed by a mask comprising the segments and features to backside actinic radiation that impinges on the segments and features from below the segments, the backside radiation passing through the segment openings;
• and
• removing at least part of the material of the primary layer not exposed to the backside radiation.
