    摘要： A gate wiring electrode is formed into a ladder-like pattern. Moreover, between source electrodes and drain electrodes in the entire Switch MMIC, the gate wiring electrodes are disposed. Furthermore, at a cross part between the gate wiring electrode and the source electrode or the drain electrode, a nitride film having a large relative dielectric constant and a polyimide or a hollow part having a small relative dielectric constant are disposed. Accordingly, a capacitance at the cross part is reduced. Thus, a second harmonic wave level can be lowered. Moreover, a leak of a high-frequency signal between the drain electrode and the source electrode can be prevented. Thus, a third harmonic level can be lowered. Consequently, distortion characteristics of the Switch MMIC can be significantly improved.

    摘要翻译： 栅极布线电极形成梯状图案。 此外，在整个开关MMIC中的源极和漏极之间设置栅极布线电极。 此外，在栅极配线电极与源电极或漏极之间的交叉部分设置相对介电常数大的氮化物膜和具有小的相对介电常数的聚酰亚胺或中空部。 因此，交叉部分的电容减小。 因此，可以降低二次谐波电平。 此外，可以防止漏极和源电极之间的高频信号的泄漏。 因此，可以降低三次谐波电平。 因此，可以显着提高开关MMIC的失真特性。

    摘要： Protecting elements are respectively connected between a control terminal Ctl and a ground terminal GND of a logic circuit L, between a point Cp and a ground terminal GND, and between a power supply terminal VDD and a ground terminal GND thereof. With this, an E-FET, constituting an inverter 70, and capacitors Ci and Cr can be protected from electrostatic breakdown due to external static electricity. Since the protecting element can be constituted by requisite components for the logic circuit, an additional step or structure is not especially required to provide the protecting element.
