Claim Text:
1. A method for fabricating a charge-encoded microelectronic component, the method comprising: forming a first charge-inducing material structure on an upper surface of said microelectronic component, said first charge-inducing material structure having a first surface chemistry exhibiting a first polarity; forming a sacrificial metal mask over a first portion of said first charge-inducing material structure such that a second portion of said first charge-inducing material structure is exposed by said sacrificial metal mask; forming a second charge-inducing material structure on the exposed second portion of said first charge-inducing material structure, said second charge-inducing material structure having a second surface chemistry exhibiting a second polarity; and removing said sacrificial metal mask, whereby said upper surface includes a first region having the first polarity, and a second region having the second polarity, wherein forming said first charge-inducing material structure comprises depositing a hydrophylic material, and wherein forming said second charge-inducing material structure comprises depositing a hydrophobic material.
