This glass bonding material (21) is made of a cladding material (1) in which at least a first layer (11) made of an Al-based alloy and configured to be bonded to glass and a second layer (12) made of an FeNi based alloy having a thermal expansion coefficient from 30 C. to 400 C. of 11.510.sup.6 (K.sup.1) or less are bonded.

A feedthrough for providing an electrical connection is provided. The feedthrough comprises a conductor and a quartz or a glass structure configured to surround at least a portion of the conductor and provide isolation to the conductor. The conductor and the quartz or glass structure may be coaxially arranged. The feedthrough can provide an electrical connection between an inside and outside of a vacuum chamber that contains a sample.

The present invention provides a bonding method (S1) which is capable of achieving a high adhesive force without carrying out any special treatment on the second member (14), even in a case where the first member (11) has a surface on which a gold thin film (12) is formed. The first member (11) is made of a material other than gold and has a surface on which the gold thin film (12) is formed. The bonding method (S1) includes the steps of: (S11) irradiating, with laser light, at least part of a specific region (12a) of the surface of the first member (11), so that a base of the thin film (12) is exposed in the at least part of the specific region (12a); and (S12) bonding the second member (14) to the specific region (12a) by use of an adhesive (13).

A method of processing a double sided wafer of a microelectromechanical device includes spinning a resist onto a first side of a first wafer. The method further includes forming pathways within the resist to expose portions of the first side of the first wafer. The method also includes etching one or more depressions in the first side of the first wafer through the pathways, where each of the depressions have a planar surface and edges. Furthermore, the method includes depositing one or more adhesion metals over the resist such that the one or more adhesion metals are deposited within the depressions, and then removing the resist from the first wafer. The method finally includes depositing indium onto the adhesion metals deposited within the depressions and bonding a second wafer to the first wafer by compressing the indium between the second wafer and the first wafer.

In some embodiments, a method comprises: depositing an adhesion layer comprising manganese oxide (MnO.sub.x) onto a surface of a glass or glass ceramic substrate; depositing a first layer of conductive metal onto the adhesion layer; and annealing the adhesion layer in a reducing atmosphere. Optionally, the method further comprises pre-annealing the adhesion layer in an oxidizing atmosphere before annealing the adhesion layer in a reducing atmosphere.

A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members. One-way crack propagation is achieved by providing a weaker member region only on the downstream side of each inter-structure bond.

The present invention relates to structure including an interfacial seal between a glass-ceramic component and a metal component, as well as methods for forming such structures. In particular embodiments, the interfacial seal includes a metal oxide. Such interfacial seals can be beneficial for, e.g., hermetic seals between a glass-ceramic component and a metal component.
