A method of forming crystalline semiconducting layers on low melting or low softening point substrates includes the steps of providing an aqueous solution medium including a plurality of semiconductor nanoparticles dispersed therein having a median size less than 10 nm, and applying the solution medium to at least one region of a substrate to be coated. The thermal conduction plate provided in contact with the thermal head. A network terminating device 2 converts a local IP address described in a header of the packet to a global IP address, and sends it to a femto concentrator 4.
