There is provided a process for producing an integrated circuit, wherein not only can conductive fine particles be deposited efficiently and densely in minute wiring channels and connecting holes but also a circuit of low wiring resistance and high density can be formed and wherein a high-degree integration can be achieved to thereby bring about an economic advantage. The laser diode package includes a laser diode bar, at least one heat sink, and at least one exothermic layer. The direction of transmission is selected responsive to the direction in which the best electromagnetic signal reception was received. This effect is near-universal in bright regions of a scene. The shifted position may be stored in memory to be recalled for future use.
