摘要:
Die vorliegende Erfindung betrifft einen Kupfer-Keramik-Verbund, umfassend: - ein Keramiksubstrat, das Aluminiumoxid enthält, - eine auf dem Keramiksubstrat vorliegende Beschichtung aus Kupfer oder einer Kupferlegierung, wobei das Aluminiumoxid einen mittleren Korn-Formfaktor R a (Al 2 O 3 ), bestimmt als arithmetischer Mittelwert aus den Formfaktoren R der Körner des Aluminiumoxids, von mindestens 0,4 aufweist.
摘要:
Provided is a bonded substrate mainly for mounting a power semiconductor in which the reliability to a thermal cycle has been enhanced as compared with a conventional one. In a bonded substrate in which a copper plate is bonded to one or both main surface(s) of a nitride ceramic substrate, a bonding layer consisting of TiN intervenes between the nitride ceramic substrate and the copper plate and is adjacent at least to the copper plate, and an Ag distribution region in which Ag atoms are distributed is set to be present in the copper plate. Preferably, an Ag-rich phase is set to be present discretely at an interface between the bonding layer and the copper plate.
摘要:
A transmissive composite film is described that may be applied to the backside of a microelectronic device, for example an integrated circuit die or a bridge. A microelectronic die package in one example has a substrate, an integrated circuit die attached and electrically connected to the substrate, the die having a front side with electrical attachments and a backside, and a composite film attached to a backside of the die, the composite film having a polymer base with nano-fillers to protect the backside of the die.
摘要:
Methods of continuous fabrication of features in flexible substrates are disclosed. In one embodiment, a method of fabricating features in a substrate web includes providing the substrate web arranged in a first spool on a first spool assembly, advancing the substrate web from the first spool and through a laser processing assembly comprising a laser, and creating a plurality of defects within the substrate web using the laser. The method further includes advancing the substrate web through an etching assembly and etching the substrate web at the etching assembly to remove glass material at the plurality of defects, thereby forming a plurality of features in the substrate web. The method further includes rolling the substrate web into a final spool.
