A quartz glass crucible 1 having a cylindrical side wall portion 10a, a bottom portion 10b, and a corner portion 10c connecting the side wall portion 10a and the bottom portion 10b to each other includes a transparent layer 11 made of quartz glass that does not contain bubbles, a bubble layer 12 formed outside the transparent layer 11 and made of quartz glass containing a large number of bubbles, and a semi-molten layer 13 formed outside the bubble layer 12 and made of raw material silica powder solidified in a semi-molten state, wherein at least one semi-molten layer-removed portion 13X is formed as a recessed region from which a portion of the semi-molten layer 13 has been removed toward an inner side of the quartz glass crucible 1.

The present invention relates to a glass metallization process for through glass vias with a high aspect ratio. The process includes a single-sided coating step, a bonding step, a drilling step, a pre-lubricating step and a metallization step; or a drilling step, a single-sided coating step, a bonding step, a pre-lubricating step and a metallization step. Since the walls of the first and second glass substrates, the first and second seed layers and a bonding layer at the vias have undergone a pre-lubricating process, it is easy for the growth of the metal material during the electroplating process. Also, the metal material grows outward from a center of the stacked structure of the first and second glass substrates to completely fill the vias, thereby being able to be applied to vias with a higher aspect ratio without creating air gaps, making the electroplating process simpler and improving the electroplating yield.

To provide glass including a colored layer and a manufacturing method thereof. Provided is glass containing one or more glass components selected from the group consisting of Ti ions, Nb ions, W ions, and Bi ions. The glass includes a colored layer having an arbitrary shape.

A coated glass element includes: a glass surface; and a coating that coats at least part of the glass surface. The coating includes at least one layer. The at least one layer of the coating fulfills the following parameter: [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.].sub.20/[Si.sub.2C.sub.5H.sub.15O.sub.2.sup.].sub.801.0. [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.].sub.20 are counts of [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface and [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.].sub.80 are counts of [Si.sub.2C.sub.5H.sub.15O.sub.2.sup.].sub.80 ions, measured by a TOF-SIMS, at 80% of a time a sputter gun beam needs to reach the glass surface.

Implementations of the present disclosure generally relate to liner layers and methods of forming liner layers for through glass vias. In one or more implementations, a liner layer is deposited on a glass substrate having a plurality of vias disposed through the glass substrate. The method includes depositing an adhesion layer onto and in a via of the plurality of vias to form the adhesion layer, the adhesion layer having a thickness of about 100 Angstroms to about 550 Angstroms, a tensile stress of about 30 MPa to about 80 MPa, and a Young's modulus of about 115 GPa to about 200 GPa and depositing a second layer onto the adhesion layer, the second layer having a thickness of about 2,000 Angstroms to about 60,000 Angstroms, a compressive stress greater than about 50 MPa, and a Young's modulus of about 35 GPa to about 70 GPa.
