Programmable charge storage arrays and associated manufacturing devices and systems

A charge storage cell comprising:

• a conductive substrate;
• a vertical post comprising a first insulating material coupled to the conductive substrate;
• a conductive cap coupled to the vertical post;
• and
• a top side planarizing layer comprising a second insulating material and covering the conductive cap;
• wherein the conductive cap is operable to support an electric charge injected through the top side planarizing layer by a modulated charged particle beam.

A method of storing charge in a predetermined pattern, the method comprising:

• providing a substrate including a plurality of charge storage cells, each of the plurality of charge storage cells including:
• a conductive pad coupled to the substrate;
• and
• an insulative layer comprising an insulating material and covering the conductive pad;
• injecting a first electric charge onto a first conductive pad through a first insulative layer, wherein the first conductive pad is associated with a first charge storage cell;
• and
• injecting a second electric charge different from the first electric charge onto a second conductive pad through a second insulative layer, wherein the second conductive pad is associated with a second charge storage cell,
• wherein each charge storage cell of the plurality of charge storage cells is substantially free of any semiconductor material.
