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.

The invention relates to a method for forming a glass item, in particular a three-dimensionally formed flat glass item, wherein the following steps are carried out: arranging a flat formation of glass, for example a flat glass pane of homogeneous thickness or a flat glass pane of inhomogeneous thickness or a preformed flat glass pane blank or liquid two-dimensionally spread glass, between a mould plunger and a melt of liquid metal, in particular tin; tempering of at least one part to be formed of the flat formation of glass to a forming temperature of the glass at which the glass has a viscosity in the range from 10 Pas to 106.5 Pas, preferably in the range from 10 Pas to 104 Pas and particularly preferably in the range from 10 Pas to 103 Pas; forming the flat formation of glass by moving the mould plunger and a surface of the molten metal towards each other, preferably by means of at least one linear movement, for example by means of a linear motor or servomotor, so that the flat formation of glass is pressurised either by the mould plunger on the one hand and by the molten metal on the other hand and is formed by the pressurisation on both sides and/or by suctioning and conforming the flat formation of glass onto the mould plunger; cooling the formed flat formation of glass to a handling temperature below the forming temperature at which the glass has a viscosity of ?107 Pas; and demoulding the cooled flat formation; as well as a device for carrying out the method and a use of a molten metal for carrying out the method.

A source material, which is based on a glass, is arranged on a working surface of a mold substrate. The mold substrate is made of a single-crystalline material. A cavity is formed in the working surface. The source material is pressed against the mold substrate. During pressing a temperature of the source material and a force exerted on the source material are controlled to fluidify source material. The fluidified source material flows into the cavity. Re-solidified source material forms a glass piece with a protrusion extending into the cavity. After re-solidifying, the glass piece may be bonded to the mold substrate. On the glass piece, protrusions and cavities can be formed with slope angles less than 80 degrees, with different slope angles, with different depths and widths of 10 micrometers and more.
