【実施例】【Example】

以下、本考案を図面に基づいて説明する。 図1(イ)は本考案の半導体装置の一実施例を示す構成図であり、(ロ)図は その回路構成図である。図1において、ICチップ上にオペアンプA1 があり、 ICチップ上のパッドにバイパスコンデンサC1 ,C3 が埋め込まれている。オ ペアンプA1 とバイパスコンデンサC1 ,C3 とは、ボンディングワイヤ−で接 続され、ICのピンから外付け回路に接続される。したがって、バイパスコンデ ンサはIC内で実現されている。 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1A is a configuration diagram showing an embodiment of the semiconductor device of the present invention, and FIG. 1B is a circuit configuration diagram thereof. In FIG. 1, an operational amplifier A1 is provided on the IC chip, and bypass capacitors C1 and C3 are embedded in the pads on the IC chip. The operational amplifier A1 and the bypass capacitors C1 and C3 are connected by a bonding wire, and are connected from the IC pin to an external circuit. Therefore, the bypass capacitor is realized in the IC.

【0007】 このように、バイパスコンデンサC1 ,C3 をICチップ上のパッドに埋め込 むことで、オペアンプA1 との接続の際の配線を短くでき、外部からの対ノイズ 特性が向上する。したがって、オペアンプA1 に供給される電源が安定し、オペ アンプA1 が動作する際の特性も向上する。また、素子数を減少でき、基板に外 付け回路を実現する際、より少ない素子で回路を組むことができ、ボ−トの実装 面積を小さくできる。By embedding the bypass capacitors C1 and C3 in the pads on the IC chip in this way, the wiring for connection with the operational amplifier A1 can be shortened and the noise resistance characteristic from the outside is improved. Therefore, the power supplied to the operational amplifier A1 is stabilized, and the characteristics when the operational amplifier A1 operates are improved. Further, the number of elements can be reduced, and when an external circuit is realized on the substrate, the circuit can be assembled with fewer elements, and the mounting area of the boat can be reduced.
