Abstract
The invention relates to a method for manufacturing a semiconductor photoelectric device for an inertial navigation system, in particular to a TO-CAN coaxial small-sized packaging method for a PIN-FET high-sensitivity detector. The method comprises the following steps that: a, the surface of a TO-CAN base made of an iron, nickel and cobalt alloy material is gilded and a heat-conductive Case point is arranged on a TO-CAN base welded with a ceramic heat sink; b, the surface of the ceramic heat sink is gilded by a thin-film sputtering method, and the ceramic heat sink is welded on the TO-CAN base by epoxy resin solder; c, an integrated chip, a detector PD chip and a filter capacitor are welded on the TO-CAN base by the epoxy resin solder; and d, a connecting chip is connected with an external connecting lead by welding a gold wire. Three fragmented components of FET, PNP and NPN are integrated on a chip, so that the device small in size is conveniently packaged into a TO-CAN coaxial small-sized device, and has the advantages of small size and low power consumption compared with the device packaged by the traditional butterfly packaging method.
Description
Technical field
The present invention relates to be used for the semiconductor photoelectric device manufacturing of inertial navigation system, specifically is the coaxial miniaturization method for packing of a kind of PIN-FET highly-sensitive detector TO-CAN.
Background technology
At present, for the inertial navigation optic fiber gyroscope to miniaturization require increasingly highly, and existing photoelectric device can't satisfy the instructions for use of the overall volume miniaturization of optic fiber gyroscope.
Summary of the invention
The present invention wants the technical solution problem to be, provides a kind of and can reduce the volume of photoelectric device, the coaxial miniaturization method for packing of PIN-FET highly-sensitive detector TO-CAN of reduction power consumption.
Method of the present invention is:
A. gold-plated to the TO-CAN susceptor surface of teleoseal material, adopt the epoxy resin scolder that ceramic heat sink is welded on the TO-CAN base, welding the node that is provided for heat conduction on the TO-CAN base of ceramic heat sink;
B. adopt thin film sputtering technology to the ceramic heat sink surface gold-plating;
C. adopt the conductive epoxy resin scolder to be welded on the TO-CAN base integrated chip, detector PD chip, filter capacitor;
D. carry out the spun gold weldering, connect chip in succession and connect lead outward.
Method of the present invention has satisfied the requirement of Performance And Reliability simultaneously, its realize miniaturization the most key the discrete component on the ceramic circuit board to be integrated in one be on the integrated chip of substrate with the GaAs with exactlying, the excessive problem of volume of solution discrete component.Because the components and parts of FET, PNP, these three separations of NPN are integrated on the chip, thereby its volume urinates in being packaged into the coaxial miniaturization of TO-CAN, and traditional relatively its volume of butterfly encapsulation is little, low in energy consumption.
Embodiment
The method of the embodiment of the invention is:
A. gold-plated to the TO-CAN susceptor surface of teleoseal material, adopt the epoxy resin scolder that ceramic heat sink is welded on the TO-CAN base, welding the node that is provided for heat conduction on the TO-CAN base of ceramic heat sink;
B. adopt thin film sputtering technology to the ceramic heat sink surface gold-plating;
C. adopt the conductive epoxy resin scolder to be welded on the TO-CAN base integrated chip, detector PD chip, filter capacitor;
D. carry out the spun gold weldering, connect chip in succession and connect lead outward.
[0007] device volume that obtains of inventive method of the present invention is equivalent to 30% of traditional devices volume, thereby makes that the overall volume of inertial navigation optic fiber gyroscope is littler, is convenient to be equipped in more on the polytypic, and is low-cost simultaneously.
