Japanese Patent JP3123760
Kind Code:
B2
Abstract:
PURPOSE:To reduce the size of an optical signal module by a method wherein the module is provided with two lead frames, which are respectively arranged on two layers and are a lead frame for optical semiconductor mounting use and a lead frame for mounting a semiconductor chip constituting a peripheral circuit. CONSTITUTION:Two lead frames 6 and 7 are respectively arranged on two upper and lower layers, an optical semiconductor element 1, such as a light- emitting diode, a photodetecting diode or the like, is mounted on the upper side lead frame 6, a semiconductor chip 2, which is an integrated circuit constituting a peripheral circuit, such as a drive circuit, a photodetecting signal processing circuit or the like, is mounted on the lower side lead frame 7 and after being electrically connected to each other via bonding wires 5, the lead frames are encapsulated in a case 3 which is a transparent resin mold. Thereby, a reduction in the size of an optical signal module becomes possible and at the same time, the erroneous operation of the module, which is caused by an effect to the peripheral circuit due to an optical signal of the element 1, can be suppressed.
