There is disclosed a kind degradable material and its disposable products, and their manufacturing process. This allows a programming voltage for the device to be imparted to the floating gate through capacitive coupling, thus changing the state of the device. This improves the circuit linearity whilst enabling a high input impedance to be obtained. As a result, less time and energy is expended in drying the surfaces, and redeposited residue is minimized, thereby improving overall process quality and facilitating economical reuse of the tray carrier.
