ABSTRACT:
A method for cutting an electrical conductive layer having a heat-absorbing film deposited thereon, by irradiating an energy beam on a portion of the electrical conductive layer intended to be cut. The energy beam is irradiated on the film, whereby the portion of the electrical conductive layer melts and alloys with the heat-absorbing film due to the energy absorbed and transferred by the heat-absorbing film.
