The ornamental design for a reactortube for semiconductorproduction devices, as shown and described.
FIG. 1 is a front view of a reactor tube for semiconductor production devices, showing our new design;
FIG. 2 is an enlarged cross-sectional view, along line 2-2 in FIG. 1;
FIG. 3 is a top plan view thereof;
FIG. 4 is a bottom plan view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is a left side view thereof; and,
FIG. 7 is a cross-sectional view, along line 7-7 in FIG. 6, shown with additional environment related to use being shown in broken lines.
The broken lines shown in the drawings represent portions of the reactor tube for semiconductor production devices that form no part of the claimed design. The rear view of the reactor tube for semiconductor production devices has been omitted because it does not illustrate the claimed design.
