Disclosed are methods and devices for producing very fine particles which are then coated with protective polymers in another step of the process. At least one N-type transistor and at least one P-type transistor separate from the digital circuit are sized to represent the total area of the corresponding type transistors in the digital circuit. Each X is independently selected from the group consisting of alkylene and arylalkylene, wherein alkylene and arylalkylene are each optionally interrupted by at least one ether linkage and optionally terminated by \u2014N\u2014C\u2014 or \u2014O\u2014C\u2014.
