Abstract

PROBLEM TO BE SOLVED: To wire the inside of the package of a Peltier cooler with a single process by providing an electrode for supplying current on the low or high temperature-side surface of the Peltier cooler, incorporating the Peltier cooler in an optical element module, and then wiring the package by wire bonding. SOLUTION: After a laser diode 4, a lens 5, a thermistor 6, and a photodiode 3 have been mounted on a subcarrier 2, the subcarrier 2 is fixed to the low- temperature substrate 11 of a Peltier cooler 9. Then, the cooler 9 is housed in a package 1, and a high-temperature substrate 10 of the cooler 9 is fixed to the bottom of the package 1. In addition, a negative electrode 12 and a positive electrode 13 are connected in series with a Peltier element via through- holes 14. Moreover, the electrodes of the laser diode 4, the thermistor 6, and the photodiode 3 and the electrodes 12 and 13 of the cooler 9 are connected to the wiring pattern of a package-connecting substrate 8 through Au wires 7. Therefore, the internal wiring of the package 1 can be performed with a single process.

In the above prior art,
Supply current to the Peltier Eura by lead wiring,
Others are performed by wire bonding, so the package internal wiring process must be divided into two processes.
Further, since the lead wiring process is difficult to be automated and mechanized and is performed manually, there is a disadvantage that the work time is longer than that of the wire wiring process.

In other words, by providing a current supply electrode on the surface of the substrate on the low-temperature side or high-temperature side of the Peltier cooler and incorporating the Peltier cooler in the optical element module, the lead wiring step which requires a long wiring work time is eliminated, and the laser diode is removed. In addition, wire bonding wiring can be performed in the same process as the wiring process of other elements such as a monitor photodiode and a thermistor, and as a result, the work time for wiring inside the package is reduced.
