The present disclosure provides a method for manufacturing a double-sided cooling type power module including separately patterning a bonding material on a base film into two regions, positioning a semiconductor chip on the patterned bonding material, transferring the patterned bonding material to one surface of the semiconductor chip by pressurizing the semiconductor chip, positioning the bonding material of the semiconductor chip on an upper electrode layer formed on an upper substrate to be in contact with the upper electrode layer, and sintering an upper bonding layer by pressurizing and heating the semiconductor chip. According to the present disclosure, it is possible to separately dispose the bonding material on each of gate and source electrode parts on an upper portion of the chip even without protrusion to directly bond the chip and the substrate.

A semiconductor device includes a substrate including, on a surface thereof, a first conductive pad and a first insulating layer formed around the first conductive pad, a semiconductor chip including, on a surface thereof, a second conductive pad and a second insulating layer around the second conductive pad, an intermediate layer formed between the substrate and the semiconductor chip, and including a conductive portion between the first and second conductive pads, and an insulating portion between the first and second insulating layers, and a molecular bonding layer formed between the substrate and the intermediate layer, and including at least one of a first molecular portion covalently bonded to a material of the first conductive pad and a material of the conductive portion, and a second molecular portion covalently bonded to a material of the first insulating layer and a material of the insulating portion.

A semiconductor device includes a base, a semiconductor chip on the base, a conductive bonding layer between a surface of the base and a surface of the semiconductor chip, the conductive bonding layer including a resin and a plurality of conductive particles contained in the resin, and a molecular bonding layer between the surface of the semiconductor chip and a surface of the conductive bonding layer, and including a molecular portion covalently bonded to a material of the semiconductor chip and a material of the conductive bonding layer.

A manufacturing method includes the step of laminating a sheet assembly onto chips arranged on a processing tape, where the sheet assembly has a multilayer structure including a base and a sinter-bonding sheet and is laminated so that the sinter-bonding sheet faces the chips, and subsequently removing the base B from the sinter-bonding sheet. The chips on the processing tape are picked up each with a portion of the sinter-bonding sheet adhering to the chip, to give sinter-bonding material layer-associated chips. The sinter-bonding material layer-associated chips are temporarily secured through the sinter-bonding material layer to a substrate. The sinter-bonding material layers lying between the temporarily secured chips and the substrate are converted through a heating process into sintered layers, to bond the chips to the substrate. The semiconductor device manufacturing method is suitable for efficiently supplying a sinter-bonding material to semiconductor chips while reducing loses of the sinter-bonding material.

A module, comprising an electronic component having a first electrode, a mounting board having a second electrode, a solder-bump configured to connect the first electrode and the second electrode, and a thermoplastic resin member configured to contact both the first electrode and the second electrode and cover the solder-bump, so as to form a space between the electronic component and the mounting board.

One aspect relates to a method for producing a substrate adapter for the connecting to an electronic component, including arranging at least one contacting material layer between at least one side of a carrier and a surface of a substrate such that the contacting material layer has at least one predetermined breaking point, and joining the carrier and the substrate to the contacting material layer. One aspect also relates to a substrate adapter for connecting to an electronic component.

Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.

Methods for fabricating and refurbishing an assembly are disclosed herein. The method begins by applying an adhesive layer onto a first substrate. A second substrate is placed onto the adhesive layer, thereby securing the two substrates together, the adhesive layer bounding at least one side of a channel that extends laterally between the substrates to an exterior of the assembly. And, the substrates and the adhesive layer are subjected to a bonding procedure and allowing outgassing of volatiles from the adhesive layer to escape from between the substrates through the channel, wherein the substrates bonded by the adhesive layer form a component for a semiconductor vacuum processing chamber.
