Abstract:
Verfahren zum Herstellen einer Substratanordnung (10, 10') zur Verbindung mit einem Elektronikbauteil (50; 51), umfassend die Schritte: - Bereitstellen eines Substrates (20), insbesondere eines DCB-Substrats, eines PCB-Substrats oder eines Leadframes, mit einer ersten Seite (22) und einer zweiten Seite (23), - abschnittsweises Aufbringen eines Vorfixiermittels (30) auf die erste Seite (22) des Substrates (20). Die Erfindung betrifft auch eine entsprechende Substratanordnung (10, 10') sowie ein entsprechendes Verfahren zum Verbinden eines Elektronikbauteils (50, 51) mit der Substratanordnung (10, 10'). Durch die erfindungsgemäßen Maßnahmen wird beim Transport vom Ort des Bestückens der Substratanordnung (10, 10') mit dem Elektronikbauteil (50, 51') zum Ort des Verbindens eine ausreichende Transportfestigkeit erzeugt. Das Vorfixiermittel (30) kann auch alternativ oder zusätzlich auf die erste Seite (52) des Elektronikbauteils (50, 51) abschnittsweise aufgebracht werden. Auf die Substratanordnung (10, 10') und/oder auf das Elektronikbauteil (50, 51) kann vor dem Aufbringen des Vorfixiermittels (30) ein Kontaktierungsmaterial (25) aufgebracht werden. Das Vorfixiermittel (30) kann zumindest abschnittsweise seitlich des Kontaktierungsmaterials (25) aufgebracht werden, derart, dass das Vorfixiermittel (30) dicker als das Kontaktierungsmaterial (25) ist. Nach dem Verbinden kann auf der ersten Seite (22) des Substrates (20) und/oder auf der dem Substrat (20) zugewandten ersten Seite (52) des Elektronikbauteils (50, 51) abschnittsweise ein Rest (31) des Vorfixiermittels (30) ausgebildet sein.
Abstract:
According to the present invention, a semiconductor device having superior electrical conductivity is provided. The semiconductor device (10) of the present invention is provided with a base material (2), a semiconductor element (3), and an adhesive layer (1) that adheres the base material and the semiconductor element while interposed there between. In the adhesive layer (1) of the semiconductor device (10), a metal particle and an insulating particle are dispersed, and the metal particle has flaked shape or ellipsoidal/spherical shape. As the content percentage by volume of the metal particle in the adhesive layer is a and the content percentage by volume of the insulating particles in the adhesive layer is b, the content percentage (a+b) by volume of fillers in the adhesive layer is 0.20 or more and 0.50 or less and the content percentage a/(a+b) by volume of the metal particles in the fillers is 0.03 or more and 0.70 or less.

There is provided an adhesive composition comprising: (A) a silicone resin constituted of a repeating unit represented by the following general formula (1); (B) a thermosetting resin; and (C) a compound having a flux activity, where R 1 to R 4 represent univalent hydrocarbon groups having carbon numbers from 1 to 8, which are equal to or different from each other; each of 1 and m is an integer from 1 to 100; each of a, b, c, and d is 0 or a positive number and meets 0
Abstract:
An object of the invention is to provide a method for producing a conductive member having low electrical resistance, and the conductive member is obtained using a low-cost stable conductive material composition that does not contain an adhesive. A method for producing a semiconductor device in which silver or silver oxide provided on a surface of a base and silver or silver oxide provided on a surface of a semiconductor element are bonded, includes the steps of arranging a semiconductor element on a base such that silver or silver oxide provided on a surface of the semiconductor element is in contact with silver or silver oxide provided on a surface of the base, temporarily bonding the semiconductor element and the base by applying a pressure or an ultrasonic vibration to the semiconductor element or the base, and permanently bonding the semiconductor element and the base by applying heat having a temperature of 150 to 900°C to the semiconductor device and the base.
Abstract:
A two-part adhesive, characterized by being essentially composed of an acrylic monomer, a peroxide, a reducing agent, an epoxy resin precursor and a curing agent and being separated into agent (A) containing one or two components selected from among an acrylic monomer, a peroxide and a reducing agent and agent (B) containing the other components that have not been selected for agent (A). This adhesive can constantly give a highly reliable bonding which is free from heat stress and excellent in heat resistance.
Abstract:
The present invention is characterized by comprising a two-pack adhesive of an A agent selected from components, an acrylic monomer, a peroxide, a reducing agent, an epoxy resin precursor and a curing agent and containing at least one or two of the acrylic monomer, the peroxide and the reducing agent, and a B agent containing all of the remaining components which are not selected in the A agent. The use of this adhesive makes it possible to stably obtain the bonding free from a thermal stress with the excellent heat resistance and the good reliability.
