FIELD: machine-building.
SUBSTANCE: invention related to flowing media ejection device and to the device control electrical chain. Half-conductor system contains an undercoat, which has first surface, first insulation material, located on at least the first surface segment, and first insulation material contains many holes, which forms a route to the first surface, a first conducting material, located on the first insulation material, in a way that many holes basically are free of the first conduction material, a second insulation material, located on the first conduction material and partly on the first insulation material, in a way that many holes basically are free of the second insulation material, and second conduction material, located on the second insulation material and inside of the many holes, in a way that some part of the second conduction material, located on the second insulation material, has electrical contact with the undercoat.
EFFECT: invention has higher technical requirements at manufacturing cost decrease.
