Patent ID: 8273671

Claim:
A process for producing a multi-layer wiring for a radio-frequency driven chip, comprising the steps of: using the radio-frequency driven chip as a carrier and a substrate when producing the multi-layer wiring; arranging a contact-connecting region on the substrate for electrical interconnection with the radio-frequency driven chip; depositing a structured glass layer having a loss factor tan δ of less than or equal to 70*10 −4 in at least a frequency range above 1 GHz and at least one opening over the contact-connection region; and applying at least one conductor structure to the structured glass layer, wherein the at least one conductor structure has electrical contact with the contact-connection region, wherein said step of depositing a structured glass layer comprises electron beam evaporation of glass material from a target that is arranged opposite and at a distance from the substrate to be coated, and wherein said step of depositing a structured glass layer comprises depositing a material having the following composition in percent by weight: SiO 2 71 ± 5, B 2 O 3 26 ± 5, Al 2 O 3 1 ± 0.2, K 2 O 1 ± 0.2, Li 2 O 0.5 ± 0.2, and Na 2 O 0.5 ± 0.2.
