Background technique
The science and technology of 21 century be it is with rapid changepl. never-ending changes and improvements, for electronics industry as hi-tech industry, technology development is even more one
Day a thousand li.Currently, with multimedia service, including phone, cable television (CATV), DTV and Internet quick and
Development in an all-round way, the requirement to circuit bandwidth and capacity sharply increase.In traditional electricity field, the transmission of signal and the speed of switch
Degree has been restricted.By taking electronic computer as an example, the dominant frequency of CPU has reached 2-2.9GHz, transmits on telematic link
The speed of code stream more reaches tens even thousands of Gbit.And in contrast, the bus transfer of computer still stops
In 10-100M, high only Gbit.Obviously, the rate of the connection of computer-internal bus and computer interconnection has become entirely
The bottleneck of computer environment.Therefore it has been proposed that using light as between computer-internal (inside circuit board) and computer
Interconnection means.It is, in principle, that the transmission rate connected with conducting wire is by its parasitic parameter (dead resistance, inductance and other raw electricity
Hold) influence and limitation, can not compare with light, it is especially more obvious for electrical transmission advantage in big transmission range optical transport.
There is photon biggish bandwidth and lower transmission loss to transmit in the same optical medium from crosstalk and electromagnetic interference
When multiple wavelength, different wavelength can be parallel through.So photon has all played important work in the application of person in electronics
With.
In this context, optical waveguide is to improve computer communication speed and bandwidth very for computer communication base plate

When preceding optical waveguide substrate light is drawn to the direction perpendicular to waveguide substrate, currently used is micro-structure reflecting mirror, this micro- knot
It is structure reflecting mirror complex manufacturing technology, at high cost.
Based on the above reasons, the present invention proposes a kind of three-dimensional optical waveguide production method, is suitble to the fast of small lot even single-piece
Fast-growing produces, three-dimensional structure can not only install more functional modules, also more convenient for computer circuitry layout designs.
It, can chip, sensor, display module, communication module on it as high speed and high-bandwidth communication substrate
Etc. modules and wiring board, can be used for making the substrate of computer and supercomputer, sensor base plate and artificial intelligence system
Substrate etc..
