Abstract
An electrical connection wire connects an electrical connection pad of an electrical chip and an electrical connection pad of a carrier substrate to which the electronic chip is mounted. A dielectric layer surrounds at least the bonding wire. The dielectric layer may be a dielectric sheath or a hardened liquid dielectric material. A dielectric material may also cover at least a portion of the electrical chip and carrier substrate. A liquid electrically conductive material is deposited and hardened to form a local conductive shield surrounding the dielectric layer at the bonding wire.
