In an exemplary embodiment of the present inventive concept, the first pad 120 may include a first part that extends in the first direction, a second part connected to the first part and extending in the second direction, and a third part connected to the second part and extending in the first direction.

The first pad 120 may electrically make contact with a passive element. The passive element may include a chip register. The chip register may include a single series resistance connected between the first pad 120 and the second pad 130. The first pad 120 may include a first recess 122. For example, the first recess 122 may be formed at a central portion of an inner surface of the first pad 120 toward the second pad 130, e.g., a right side surface of the first pad 120 in FIG. 1. A first electrode of the passive element may be inserted into the first recess 122. For example, the first recess 122 may be configured to receive the first electrode of the passive element. For example, the first electrode of the passive element may closely make contact with inner surfaces of the first recess 122. In addition, a gap may be formed between the first electrode of the passive element and the inner surfaces of the first recess 122.
