Semiconductor wafer having electrically connected passive device chips, passive devices and semiconductor package using the same

Abstract

A semiconductor wafer includes a plurality of passive device units, which are electrically connected across scribe lines. Passive device chips in the wafer that are adjacent to one another in a first direction are electrically connected in parallel, while passive device units adjacent to one another in a second direction are connected in series. By selecting a number of adjacent passive device units extending in the first and second direction, and separating the selected units from the wafer along the corresponding scribe lines, a passive device chip having a desired electrical characteristic (e.g., capacitance or resistance) can be obtained. Such passive device chips may be assembled in a semiconductor package where they are electrically connected to active devices.
