The composite chip component includes: plurality of chip elements which are disposed so as to be mutually spaced apart upon a common substrate, and which have mutually different functions; and a pair of electrodes which, in each of the chip elements, are formed on the surface of the substrate. As a result, it is possible to reduce the bond area (footprint) for the mounting substrate, and therefore, it is possible to provide a composite chip component capable of achieving efficiency of mounting operation.

Composite chip component, circuit assembly and electronic apparatus

A probe card includes a board or silicon substrate; a plurality of probes (terminals) at a first surface of the board, the respective probes having a first extending portion extending along the first surface of the board; a plurality of through-holes formed in correspondence to the respective probes and penetrating between the first and second surfaces of the board; through electrodes embedded in the respective through-holes and conductively connected to the probes in the respective through-holes; and a wiring at the second surface of the board conductively connected to the through electrodes, the wiring having a second extending portion extending along the second surface of the board, wherein the first extending portion and the second extending portion extend in different directions from each other, and a space is formed across the entire width of the first extending portion between the first extending portion and the first surface of the board.

Probe card

Provided is a method for manufacturing a probe card which inspects electrical characteristics of a plurality of semiconductor devices in batch. The method includes: a step of forming a plurality of probes, which are to be brought into contact with external terminals of the semiconductor devices, on one side of a board which forms the base body of the probe card; a step of forming on the board, by photolithography and etching, a plurality of through-holes which reach the probes from the other side of the board; a step of forming, in the through-holes, through electrodes to be conductively connected with the probes, respectively; and a step of forming wiring, which is conductively connected with the through electrodes, on the other side of the board.
