Embodiment Construction
[0086] figure 1 A plan view structure of a semiconductor device according to an embodiment is shown. Such as figure 1 As shown in FIG. 2 , a semiconductor element 102 is mounted on a lead frame 101 and sealed by an insulating sealing portion 107 made of resin. and, in figure 1 Only the position of the insulating seal 107 is shown in .
[0087] The semiconductor element 102 is, for example, a switching element for electric power or the like. If a specific example is given, it is as follows figure 2 Two field effect transistors (FETs) made of nitride semiconductors are integrally formed on a substrate as shown. A first nitride semiconductor layer 502 serving as a channel layer and a second nitride semiconductor layer 503 serving as an electron supply layer are sequentially formed over a substrate 501 . The first nitride semiconductor layer 502 may be, for example, gallium nitride (GaN), and the second nitride semiconductor layer 503 may be, for example, aluminum galliu...
