An integrated circuit includes conductive elements and a radiation sensitive material interposed between the conductive elements and dosed to different conductivities in different portions thereof. Another aspect is a process of integrated circuit fabrication including steps of depositing a radiation sensitive material as a layer and variably dosing it with radiation to establish areas of higher and lower resistivity in the layer. A printed wiring board includes radiation sensitive material and the board further has a conductor layer affixed to the base. A transistor has a radiation sensitive material dosed to have two conductive regions separated by a gap of a lower conductivity in the radiation sensitive material, and a conductive substance deposited over the gap. These elements are useful in smart power devices, digital computers, controllers and electronic applications generally. Other devices, systems and processes are disclosed.
A smart power device comprising a microcontroller, a power switching device activated by a signal from said microcontroller, and an electrical resistance body of radiatively dosed radiation sensitive material electrically connected within the power switching device, said electrical resistance body comprising a polymer material.
A power controller system comprising a microcontroller, a power switching device activated by a signal from said microcontroller, an electrical resistance body of radiatively dosed radiation sensitive polymer material electrically connected to the power switching device, and a load element connected to said power switching device and to said electrical resistance body.
