Light-emitting element having nitride semiconductor multiquantum barrier, and process for production thereof
An Al0.95Ga0.05N:Mg (25 nm) single electron barrier can stop electrons having energy levels lower than the barrier height. Meanwhile, a 5-layer Al0.95Ga0.05N (4 nm)/Al0.77Ga0.23N (2 nm) MQB has quantum-mechanical effects so as to stop electrons having energy levels higher than the barrier height. Thus, electrons having energy levels higher than the barrier height can be blocked by making use of multiquantum MQB effects upon electrons.

In particular, for InAlGaN-based ultraviolet elements, AlGaN having the composition similar to that of AlN is used; however, it is difficult to realize a barrier having the barrier height exceeding that of AlN. Therefore, MQB effects are very important. Accordingly, it becomes possible to provide element technology for further improving deep UV light emission intensity using, as a light-emitting layer material, an AlGaInN-based material and, in particular, an AlGaN-based material. |

It is an object of the present invention to provide a power semiconductor device, which is capable of being operable regardless of thermal stress generation, reducing a heat generation from wire, securing the reliability of bonding portion when the device is used for dealing with a large amount current and/or under a high temperature atmosphere, a method of manufacturing the device and a bonding wire. In a power semiconductor device in which a metal electrode (die electrode 3) on a power semiconductor die 2 and another metal electrode (connection electrode 4) are connected by metal wire 5 using wedge bonding connection, the metal wire is Ag or Ag alloy wire of which diameter is greater than 50 μm and not greater than 2 mm and the die 3 has thereon one or more metal and/or alloy layers, each of the layer(s) being 50 Å or more in thickness and a metal for the layer is selected from Ni, Cr, Cu, Pd, V, Ti, Pt, Zn, Ag, Au, W and Al. |
