摘要： A drinking implement includes a first end section with a first opening and a second end section with a second opening. A wall made of glass extends from the first opening to the second opening. At least one of the first end section or the second end section is designed as a specific end section having at least partially a ridge, an outer edge, and an inner edge. An outer transition angle and an inner transition angle both have absolute values of less than 90 degrees.

摘要： A method for producing an ultrathin chemically toughened glass article is provided that includes: providing an ultrathin glass sheet with a first surface and a second surface joined by at least one edge, having a thickness between the first and the second surface, chemically toughening the ultrathin glass sheet to produce an ultrathin toughened glass article. The method includes applying an edge pre-treatment to the at least one edge, preferably all edges, of the ultrathin glass sheet prior to the chemical toughening in order to reduce and/or blunt edge defects and to increase resistance to breakage of the ultrathin glass sheet during the chemical toughening.

摘要： A shaped glass article is provided that is ultrathin, has two surfaces and one or more edges joining the two surfaces, and a thickness between the two surfaces. The shaped ultrathin glass article has at least one curved area with a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied. A method for producing a shaped glass article is also provided that includes providing an ultrathin glass with two surfaces and one or more edges joining the two surfaces, having a thickness between the two surfaces and shaping the ultrathin glass to a shaped ultrathin glass article by forming at least one curved area having a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied to the shaped ultrathin glass article.

摘要： A method for making a bonded article, wherein a thin glass substrate is bonded on a support substrate in the absence of any interlayer by an electrostatic adhesion process with the assistance of external pressure, the pressure is applied constantly or stepwise during the adhesion process by use of a tool such as a roll or a wheel or other movable device with curved surface. The bonded article has no defects, e.g. bubbles or inclusions, in the bonded interface, which benefits transportation of the thin glass substrate and its post-processing as well. Such defect-free bonded article is also disclosed. Pressure supported electrostatic adhesion, initiated by electrostatic charges adhesion of a two members, e.g. a substrate member and a support member, is enabled to minimize, prevent and exclude defects, distortion between the adhered surfaces.

摘要： A low CTE boro-aluminosilicate glass having a low brittleness for use in wafer-level-packaging (WLP) applications is disclosed. The glass comprises a composition in mol-% of SiO2: 60-85, Al2O3: 1-17, B2O3: 8-20, Na2O: 0-5, K2O: 0-5, MgO: 0-10, CaO: 0-10, SrO: 0-10, and BaO: 0-10. An average number of non-bridging oxygen per polyhedron (NBO) is equal to or larger than −0.2 and a ratio B2O3/Al2O3 is equal to or larger than 0.5. The NBO is defined as NBO=2×Omol/(Simol+Almol+Bmol)−4. A glass carrier wafer made from the low CTE boro-aluminosilicate glass and a use thereof as a glass carrier wafer for the processing of a silicon substrate are also disclosed, as well as a method for providing a low CTE boro-aluminosilicate glass.

摘要： A diffractive optical element is provided that includes at least two layers with different etching speeds for dry etching process. The diffractive optical element has a substrate of glass and a microstructure layer arranged on the substrate. The ratio of dry etching speed in thickness direction of the substrate to that of the microstructure layer is no more than 1:2 so that the substrate functions as an etching stop layer. The ratio of dry etching speed in horizontal direction of the substrate is substantially equal to that of the microstructure layer. The composition of glass includes, but is not limited to, Al2O3, alkaline material (M2O) and alkaline earth material (MO), where the weight percentage of Al2O3+M2O+MO>=5%.

摘要： A glass ribbon in the form of a glass roll is provided that is optimized with respect to the requirements of a long service life and at the same time compact dimensions. A bending radius on the inner side of the thin glass roll is determined by performing breakage tests on samples of the glass material, statistical parameters are determined on the basis of the breakage tests, and the statistical parameters are converted into a range of bending radii which meet the requirements on service life and the most compact dimensions possible of the thin glass roll.
