Some embodiments include methods of forming interconnects through semiconductor substrates. An opening may be formed to extend partway through a semiconductor substrate, and part of an interconnect may be formed within the opening. Another opening may be formed to extend from a second side of the substrate to the first part of the interconnect, and another part of the interconnect may be formed within such opening. Some embodiments include semiconductor constructions having a first part of a through-substrate interconnect extending partially through a semiconductor substrate from a first side of the substrate; and having a second part of the through-substrate interconnect extending from a second side of the substrate and having multiple separate electrically conductive fingers that all extend to the first part of the interconnect.

The invention concerns an integrated circuit and methods for making same. The invention is characterized in that it consists in depositing an intermediate layer (16) of dielectric material between two metal layers (102, 104). Said intermediate layer (160) is formed such that the capacitance operating at the surface between the metal layers (102, 104) is greater than 0.5 fF/ν2, for instance the intermediate layer has a relative permittivity ranging between 4 and 30, and a thickness ranging between 200 nm and 100 nm.
摘要:
A semiconductor integrated circuit comprises contact pads located over active components, which are positioned to minimize the distance for power delivery between a selected pad and one or more corresponding active components, to which the power is to be delivered. This minimum distance further enhances dissipation of thermal energy released by the active components. More specifically, a semiconductor integrated circuit comprises a laterally organized power transistor, an array of power supply contact pads distributed over the transistor, means for providing a distributed, predominantly vertical current flow from the contact pads to the transistor, and means for connecting a power source to each of the contact pads. Positioning the power supply contact pads directly over the active power transistor further saves precious silicon real estate area. The means for vertical current flow include contact pads made of a stack of metal layers comprising refractory metals for adhesion, copper and nickel as stress-absorbing metals, and gold or palladium as bondable and solderable outermost metals. The means for connecting a power source include wire bonding and solder ball interconnection.

In the present invention, the bonding pad (21) is formed in a lattice-like shape. Directly underneath the passivation layer (22), the etching stopper layer (29) is provided. An opening (23) is made through the passivation layer (22) and the etching stopper layer (29) so as to expose the bonding pad (21). The cavity sections of the lattice-like shape of the bonding pad (21) are filled with the insulating layer (27). The bonding wire (28) is connected to the lattice-shaped bonding pad (21). With this structure, the bonding error of the device manufactured by the damascening process can be avoided.
摘要:
Bond pads (394, 106) and bond pad openings (62, 108) are formed such that the bond pad openings (62, 108) are asymmetric to the conductive sections (398, 106) of the bond pads (394, 106). If the bond pads are more likely to lift from the scribe line side of the bond pad (394, 106), the bond pad openings (62, 108) are formed such that the passivation layer (52) overlies more of the conductive section (398, 106) near the scribe line (40). If the bond pads (394, 106) are more likely to lift from the other side, the passivation layer (52) overlies more of the other side of the conductive section (398, 106). In addition to reducing the risk of lifting, contamination problems should also be reduced.
摘要:
The present invention relates to a method of forming a joint (25) bonding together two solid objects (20, 22) and a joint (25) made by the method, where the joint (25) is formed by a layer (24) of a binary system of components A and B which upon heat treatment forms a porous, coherent and continuous single-phased solid-solution of the components A and B extending across a bonding layer of the joint (25) and a second phase of the components A and B dispersed in the porous, coherent and continuous single-phased solid-solution structure. Components A and B may be fully miscible in the solid state. Alternatively, the binary system of components A and B may be a partly miscible eutectic system. The first and second solid objects (20, 22) may be any physical objects which are to be bonded together, i.e. materials such as e.g. Si, SiC, GaAs, GaN, SOI, Alumina, AIN, Si3N4, glass, Kovar, Cu, Al, etc. and/or components such as e.g. MEMS, transistors, substrates, resistances, condensers, ICs, diodes, etc. The present invention has the advantages of enabling forming the bond (25) at a relatively low process temperature which may be less than the intended operation temperature of the bond (25) and also of partly remelting the bonding layer (25) if the operation temperature becomes higher than the solidus temperature. The partly remelting of the bond layer (25) according to the invention is believed to provide an advantage of releasing thermal stresses in the bond (25), possible recovery of zones with significant defect concentrations at grain boundaries, and probably also reducing the occurrence of a detrimental Kirkendall voiding effect between the bonded components (20, 22). Thus the joints (25) according to the present invention are believed to be more resilient when exposed to thermal loads such as cycling and high temperature operation, especially when the thermal cycling involves temperatures above the solidus temperature. Another benefit of the joint (25) according to the invention is that it avoids fragile intermetallic compounds.
