An interactive graphic system is provided for automatically recording lines, symbols or marks by inputting plotting information in a step-by-step mode in an interactive system. The systems comprise a data setter for specifying, among various predetermined graphs, a graph to be plotted and for setting plotting data concerning the graph thus specified, a plotter for providing records in association with input signals, a display for requiring the plotting data inputs, and a controller for suitably controlling the various sections. The system is formed into one unit, so that the plotter can directly plot the necessary records with plotting data given by the data setter, and that the plotting operation is simplified and the system itself is small in size and low in manufacturing cost.

[Objective]To restrict degradation of optical characteristics due to a resin adhesive containing an inorganic filler.[Means]The width d of a lens body 31 and the height of an inorganic filler 341 in a direction orthogonal to the surface of a substrate are set such that an inclination angle of a collimating lens 3 does not exceed a maximum tolerable inclination angle when the inorganic filler 341 is positioned near the width-wise center of the lens body 31. As a result, even when the inorganic filler 341 is inserted between the bottom surface of the collimating lens 3 and the top surface of the substrate 4, degradation of the optical characteristics of the laser module including skewing of the optical axis of the laser light and distortion of the beam shape of the laser light can be restricted.

A semiconductor device has multiple power-supply through electrodes, grounding through electrodes, and signal-routing through electrodes made through a semiconductor chip. The power-supply through electrodes, the grounding through electrodes, and the signal-routing through electrodes differ mutually in cross-sectional area. Hence, a semiconductor device and a chip-stack semiconductor device are provided which are capable of preventing the electrodes' resistance from developing excessive voltage drop, heat, delay, and loss, and also from varying from one electrode to the other.
