  • Patent number: 11148943
    Abstract: A semiconductor element is formed in a mesa portion of a semiconductor substrate. A cavity is formed in a working surface of the semiconductor substrate. The semiconductor substrate is brought in contact with a glass piece made of a glass material and having a protrusion. The glass piece and the semiconductor substrate are arranged such that the protrusion extends into the cavity. The glass piece is bonded to the semiconductor substrate. The glass piece is in-situ bonded to the semiconductor substrate by pressing the glass piece against the semiconductor substrate. During the pressing a temperature of the glass piece exceeds a glass transition temperature and the temperature and a force exerted on the glass piece are controlled to fluidify the glass material and after re-solidifying the protrusion completely fills the cavity.
