    Abstract: A three-dimensional semiconductor device may include a back-side metal layer, a lower channel pattern on the back-side metal layer, first and second lower source/drain patterns, which are spaced apart from each other in a first direction with the lower channel pattern interposed therebetween, the first lower source/drain pattern being connected to the lower channel pattern, an upper channel pattern on the lower channel pattern, a first upper source/drain pattern on the first lower source/drain pattern, the first upper source/drain pattern being connected to the upper channel pattern, a second upper source/drain pattern on the second lower source/drain pattern, and a wide via electrically connecting the first upper source/drain pattern to the second lower source/drain pattern. The wide via may include first and second via portions having first and second top surfaces, and here, the second top surface may be located at a level lower than the first top surface.

    Abstract: A semiconductor device for high-frequency amplification (100) includes a substrate (101); a first nitride semiconductor layer (103) above the substrate (101); a two-dimensional electron gas layer (105); a second nitride semiconductor layer (104); and a source electrode (301), a drain electrode (302), and a gate electrode (401) spaced apart from each other above the first nitride semiconductor layer (104). In a plan view, an active region (701) with a two-dimensional electron gas layer (105) includes a resistor (601) and the resistor (601) provided above the second nitride semiconductor layer (104). In the plan view, a non-active region (704) includes a drain terminal (803) and a gate terminal (804) connected to the drain electrode (302) or the gate electrode (401); and a first resistor terminal (805) and a second resistor terminal (806) connected to the resistor (601).
