The ornamental design for a semiconductordevice, as shown and described.
FIG. 1 is a perspective view of a semiconductor device showing my new design;
FIG. 2 is a front view thereof;
FIG. 3 is a top plan view thereof;
FIG. 4 is a bottom plan view thereof;
FIG. 5 is a left side view thereof;
FIG. 6 is an enlarged cross-sectional view taken along line 6-6 in FIG. 4; and,
FIG. 7 is an enlarged cross-sectional view taken along line 7-7 in FIG. 4.
The even broken lines illustrate portions of the semiconductor device that form no part of the claimed design. The dash-dotted lines denote the boundary of the claim and form no part of the claimed design.
In FIGS. 1 and 4, the solid line extending in the vertical length direction, and which is co-linear with an even broken line at one end and a dash-dotted line at the other end, represents a claimed structure line of an electrode plate of the semiconductor device.
