| 20130234297 | SEMICONDUCTOR DEVICE, WAFER ASSEMBLY AND METHODS OF MANUFACTURING WAFER ASSEMBLIES AND SEMICONDUCTOR DEVICES - A cavity is formed in a working surface of a substrate in which a semiconductor element is formed. A glass piece formed from a glass material is bonded to the substrate, and the cavity is filled with the glass material. For example, a pre-patterned glass piece is used which includes a protrusion fitting into the cavity. Cavities with widths of more than 10 micrometers are filled fast and reliably. The cavities may have inclined sidewalls. | 09-12-2013 |
| 20130237034 | Glass Piece and Methods of Manufacturing Glass Pieces and Semiconductor Devices with Glass Pieces - 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. | 09-12-2013 |
