    Abstract: 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.

    Abstract: Aluminum nitride particles used as a material of an aluminum nitride sintered compact are disclosed. The aluminum nitride particles may have a same crystal orientation. The aluminum nitride particles each have an aspect ratio of 3 or more, a plate-like shape, a planar length of 0.6 µm or more and 20 µm or less, and a thickness length of 0.05 µm or more and 2 µm or less.
