Abstract:
A substrate provided with an electrically conducting wire coated with an electrically insulating material is impregnated with a polymerizable material. A reception area for a chip is formed on a surface of the substrate by means of deformation. The housing area is stiffened using the polymerizable material. The chip is disposed in the reception area and an electrical connection area of the chip is connected electrically to the electrically conducting wire of the substrate.
Abstract:
A semiconductor circuit substrate includes a transistor-forming substrate and a circuit-forming substrate. The transistor-forming substrate is a GaN substrate and has a Bipolar Junction Transistor (BJT) located in its top surface. The bottom surface of the transistor-forming substrate is flat and has contact regions. The circuit-forming substrate is a material other than a compound semiconductor and has no semiconductor active elements. The circuit-forming substrate has a flat top surface, contact regions buried in and exposed at the top surface, and passive circuits. The transistor-forming substrate and the circuit-forming substrate are directly bonded together without any intervening film, such as an insulating film.
Abstract:
Hybrid bonding is described for combining one semiconductor die with another. Some embodiments include attaching small dies on a wafer to a temporary carrier, aligning the dies over a plurality of larger host dies on a host wafer using the temporary carrier, applying the small dies against the host dies using the temporary carrier so that a subset of the small dies bond to respective host dies, separating the temporary carrier so that the subset of bonded small dies are attached to a respective host die and the remaining small dies are separated with the temporary carrier, singulating the host dies, and packaging the host dies.
Abstract:
A method for bonding a first semiconductor substrate to a second semiconductor substrate by direct bonding is described. The substrates are both provided on their contact surfaces with a dielectric layer, followed by a CMP step for reducing the roughness of the dielectric layer. Then a layer of SiCN is deposited onto the dielectric layer, followed by a CMP step which reduces the roughness of the SiCN layer to the order of 1 tenth of a nanometre. Then the substrates are subjected to a pre-bond annealing step and then bonded by direct bonding, possibly preceded by one or more pre- treatments of the contact surfaces, and followed by a post- bond annealing step, at a temperature of less than or equal to 250°C. It has been found that the bond strength is excellent, even at the above named annealing temperatures, which are lower than presently known in the art.
Abstract:
Methods of bonding together semiconductor structures include annealing metal of a feature on a semiconductor structure prior to directly bonding the feature to a metal feature of another semiconductor structure to form a bonded metal structure, and annealing the bonded metal structure after the bonding process. The thermal budget of the first annealing process may be at least as high as a thermal budget of a later annealing process. Additional methods involve forming a void in a metal feature, and annealing the metal feature to expand the metal of the feature into the void. Bonded semiconductor structures and intermediate structures are formed using such methods.
