    Abstract: A first semiconductor element (laser diode) and a second semiconductor element (laser diode) are connected to each other in series between a wiring electrically connected to an anode of the first semiconductor element and a wiring electrically connected to a cathode of the second semiconductor element. In this case, each of the first semiconductor element and the second semiconductor element includes a laminated pattern having an emission layer and a plurality of semiconductor layers covering this laminated pattern.

    Abstract: A semiconductor device comprises a wiring substrate and a semiconductor chip. In the wiring substrate, a plurality of micro-elements each comprised of a stacked structure including a power supply pattern and a ground pattern is arranged at a predetermined interval. In each of the plurality of micro-elements, the power supply pattern is formed in a wiring layer located one layer above or one layer below a wiring layer in which the ground pattern is formed. A power supply potential is to be supplied to the power supply patter, and a ground potential is to be supplied to the ground patter.

    Abstract: The designing method according to an embodiment of the present invention is a method of designing a transmission line portion coupled between a transmission unit and a receiving unit, and transmitting a signal from the transmission unit to the receiving unit. Also, one-data-width distance is obtained by converting one-data-width interval, which is corresponding to a sampling period of an equalizer provided in one of the transmission unit and the receiving unit, to a distance. Further, a first reflection source for reflecting the signal is arranged at a position of the transmission line portion, where is corresponding to a ½-data-width distance corresponding to a half of the one-data-width distance. Here, the position corresponds to a grid point where a row grid line drawn on a screen used in the designing method and a column grid line drawn on the screen intersect with each other.

    Abstract: A semiconductor device comprises two memory chips, one control chip controlling each memory chip, a signal transmission path through which a signal transmission between the control chip and each memory chip is performed, and a capacitance coupled onto the signal transmission path. Also, the capacitance (capacitor element) is larger than each parasitic capacitance parasitic on each chip. Accordingly, it is possible to perform the signal transmission of the semiconductor device at high speed.

    Abstract: To provide an inexpensive semiconductor device capable of suppressing the influence by crosstalk. A semiconductor device includes a signal wiring disposed in an organic interposer, an output circuit which is coupled to a first end of the signal wiring and which sets an impedance so as to generate a reflected wave antiphase to a waveform transmitted to the first end and periodically outputs data, and an input circuit which is coupled to a second end of the signal wiring and sets an impedance so as to generate a reflected wave of the same phase as a waveform transmitted to the second end. An average delay of the signal wiring is set to be 1/integer of 2 or more relative to a half of a cycle of the data. A difference between the maximum and minimum values of a delay of a signal at each of other signal wirings disposed in the organic interposer is set to be not greater than the average delay.
