摘要: A microelectronic assembly includes a first substrate having a surface and a first conductive element and a second substrate having a surface and a second conductive element. The assembly further includes an electrically conductive alloy mass joined to the first and second conductive elements. First and second materials of the alloy mass each have a melting point lower than a melting point of the alloy. A concentration of the first material varies in concentration from a relatively higher amount at a location disposed toward the first conductive element to a relatively lower amount toward the second conductive element, and a concentration of the second material varies in concentration from a relatively higher amount at a location disposed toward the second conductive element to a relatively lower amount toward the first conductive element.

摘要: A semiconductor chip includes a semiconductor body having a lower side with a lower chip metallization applied thereto. A first contact metallization layer is produced on the lower chip metallization. A second contact metallization layer is produced on a metal surface of a substrate. The semiconductor chip and the substrate are pressed onto one another for a pressing time so that the first and second contact metallization layers bear directly and extensively on one another. During the pressing time, the first contact metallization layer is kept continuously at temperatures which are lower than the melting temperature of the first contact metallization layer. The second contact metallization layer is kept continuously at temperatures which are lower than the melting temperature of the second contact metallization layer during the pressing time. After the pressing together, the first and second contact metallization layers have a total thickness less than 1000 nm.

摘要: An anisotropic conductive film whereby electrically conductive particles can be sufficiently captured at each connection terminal while suppressing the occurrence of shorts and conduction reliability can be improved even in cases where connecting finely pitched connection terminals. The anisotropic conductive film has a structure in which electrically conductive particle units in which electrically conductive particles are arranged in a row, or electrically conductive particle units in which electrically conductive particles are arranged in a row and independent electrically conductive particles are disposed in a lattice form in an electrically insulating adhesive layer. The shortest distance La between electrically conductive particles selected from adjacent electrically conductive particle units and the independent electrically conductive particles is not less than 0.5 times the particle diameter of the electrically conductive particles and.

摘要: A semiconductor wafer stack and a method of forming a semiconductor device is disclosed. The method includes providing a wafer stack with first and second wafers bonded together. The wafers include edge and non-edge regions, and at least one of the first and second wafers includes devices formed in the non-edge region. The first wafer serves as the base wafer while the second wafer serves as the top wafer of the wafer stack, where the base wafer is wider than the top wafer, providing a step edge of the wafer stack. An edge protection seal is formed on the wafer stack, where first and second layers are deposited on the wafer stack including at the top wafer and step edge of the wafer stack. The portion of the first and second layers on the step edge of the wafer stack forms the edge protection seal which protects the devices in the wafer stack in subsequent processing.

摘要: A method of bonding a first substrate to a second substrate includes disposing a first high melting point metal layer onto a first substrate, disposing a first low melting point metal layer onto the first high melting point metal layer, disposing a second high melting point metal layer onto a second substrate, and disposing a second low melting point metal layer onto the second high melting point metal layer. The method further includes applying precursor metal particles onto the first and/or second low melting point metal layers, positioning the first and second low melting point metal layers such that the precursor metal particles contact both the first and second low melting point metal layers, and bonding the first substrate to the second substrate by heating the precursor metal particles and each metal layer to form an intermetallic alloy bonding layer between the first and second substrates.

A conductive layer is formed on a first surface of a bonded structure, the bonded structure including a first substrate bonded to a second substrate, the first surface of the bonded structure being an exposed surface of the first substrate. A patterned mask having first openings and second openings is formed on the conductive layer, the first openings and the second openings exposing portions of the conductive layer. First portions of first bonding connectors are formed in the first openings and first portions of second bonding connectors are formed in the second openings. The conductive layer is patterned to form second portions of the first bonding connectors and second portions of the second bonding connectors. The bonded structure is bonded to a third substrate using the first bonding connectors and the second bonding connectors.

摘要: A method is provided for connecting parts to be joined. A first layer sequence is applied to a first part to be joined. The first layer sequence contains silver. A second layer sequence is applied to a second part to be joined. The second layer sequence contains indium and bismuth. The first layer sequence and the second layer sequence are pressed together at their end faces respectively remote from the first part to be joined and the second part to be joined through application of a joining pressure at a joining temperature which amounts to at most 120° C. for a predetermined joining time. The first layer sequence and the second layer sequence fuse together to form a bonding layer which directly adjoins the first part to be joined and the second part to be joined and the melting temperature of which amounts to at least 260° C.

摘要: A microelectronic assembly includes a first substrate having a surface and a first conductive element and a second substrate having a surface and a second conductive element. The assembly further includes an electrically conductive alloy mass joined to the first and second conductive elements. First and second materials of the alloy mass each have a melting point lower than a melting point of the alloy. A concentration of the first material varies in concentration from a relatively higher amount at a location disposed toward the first conductive element to a relatively lower amount toward the second conductive element, and a concentration of the second material varies in concentration from a relatively higher amount at a location disposed toward the second conductive element to a relatively lower amount toward the first conductive element.
