Semiconductor laser driving apparatus, electronic equipment, and manufacturing method of semiconductor laser driving apparatus

Electronic equipment comprising:

• a substrate incorporating a laser driver;
• a semiconductor laser that has at least one light emitting point and that is mounted on one surface of the substrate in such a manner that an electrode of the light emitting point and a pattern of the substrate are connected to each other via a bump;
• connection wiring that electrically connects the laser driver and the semiconductor laser to each other with a wiring inductance of 0.5 nanohenries or less;
• and
• a sealing portion that seals a connection terminal portion of the semiconductor laser for the substrate.

A manufacturing method of a semiconductor laser driving apparatus, comprising:

• a step of forming a laser driver on an upper surface of a support plate;
• a step of forming a substrate incorporating the laser driver, by forming connection wiring of the laser driver;
• a step of, when a semiconductor laser having at least one light emitting point is mounted on one surface of the substrate in such a manner that an electrode of the light emitting point and a pattern of the substrate are connected to each other via a bump, forming connection wiring that electrically connects the laser driver and the semiconductor laser to each other via the connection wiring with a wiring inductance of 0.5 nanohenries or less;
• and
• a step of forming a sealing portion that seals a connection terminal portion of the semiconductor laser for the substrate.
