A radio frequency (RF) generating device for generating RF output signals is provided. The RF generating device includes: a controller configured to generate an RF control signal and a gain control signal; a plurality of RF signal generators, each RF signal generator being configured to generate an RF signal having at least one of a frequency and a phase determined based on the RF control signal; a plurality of RF amplification modules, each RF amplification module being configured to receive the RF signal generated by a corresponding RF signal generator and generate an RF amplification signal by controlling a gain of the RF signal based on the gain control signal; an RF switch module configured to select at least one of the RF amplification signals generated by the RF amplification modules and generate an RF output signal in a form of a multi-level pulse based on the selected at least one of the RF amplification signals; and an impedance converter connected to an electrode of an external load and configured to convert a load impedance into a target impedance having a target range, the load impedance being an impedance of the external load.

RF generating device and semiconductor manufacturing apparatus including the same

A semiconductor device is described which includes a substrate, an interlayer insulating layer provided below the substrate and including a via pad therein, a through via located at least partially within a via hole passing through the substrate and a portion of the interlayer insulating layer, a connection pad on the substrate, and a pad isolation pattern formed in the substrate to be located around the connection pad and the through via. The pad isolation pattern includes a plurality of bent portions having protrusions and recesses when viewed from a top view. As a result, cracks may be prevented from forming or growing in the semiconductor device.
