Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention Specific embodiment be described in detail.
1st, as shown in Figure 1, evaporation source A and B of the present invention is mounted in traditional continuous coating producing line, vacuum is included Coating chamber, transition chamber one, transition chamber two, chip automatic feed platform, chip automatic blanking platform, vaporizing-source system A, evaporation source System B, the pumped vacuum systems of each room.Evaporation source A and evaporation source B is distributed in the same side of coating chamber, gas pipeline B respectively It is interior vertical with substrate transfer direction holding to extend into coating chamber, for nozzle above chip, jet hole is vertical with chip holding.It is defeated Tracheae back segment B is arranged in vacuum coating room, appendix leading portion A connection crucibles.
2nd, as shown in Fig. 2, a kind of continuous coating apparatus for preventing sealing valve deposited metal film of the present invention, including: The crucible 1 of the double-layer structure of evaporation material is loaded, crucible internal layer is equipped with heating component 2, outer layer is equipped with cooling water pipe 3;Crucible side Face is equipped with feed inlet 4, is equipped with evaporation gas outlet 5a above, and evaporation gas outlet is equipped with air outlet pipe 5 with dissection, in air outlet pipe End is equipped with conical valve 6, it has Serve Motor Control;The leading portion 8A of air outlet pipe upper end connect band appendix 8 with dissection, gas transmission One group of fumarole is set using the linear alignment in the back segment 8B of pipe, each fumarole, which uses, is threadedly coupled nozzle 9, after appendix Section 8B is arranged in the vacuum chamber of coating wire.
Crucible 1 is equipped with the vacuum suction device being connected with interlayer and the nitrogen for being quickly cooled down crucible and gas pipeline Device of air;
As shown in Figures 3 and 4, self-styled sealed valve body 7 is equipped in the air outlet pipe 5 between cone valve 6 and crucible, for preventing even Deposition film metal film in continuous coating machine sealing valve;The self-styled sealing valve is loop component, including outer layer insulating tube 7a and interior Layer heating dish 7b, is equipped with the interlayer unicom of gap and air outlet pipe 5 between outer layer insulating tube and internal layer heating dish, in internal layer heating dish One group of bellmouth 7h with air outlet pipe unicom is evenly distributed with, internal layer heating dish periphery is equipped with one group of cooling tube 7c, and cooling tube is equipped with Safety valve 7d is so designed that in order to when self-styled sealing valve does not enable, because of expansion inside heating status, cooling water pipe And there are one safe releases for the pressure generated.It ensure that the security used.
Further prioritization scheme is that self-styled sealing valve uses two times that the area of air inlet 7f is gas outlet 7g areas, always Outlet area it is equal with the cross-sectional area of air outlet pipe 5, and air inlet 7f is located at crucible one side, gas outlet 7g is located at cone valve 6 one sides.The stability of steam stream overall flow can both be ensured by being so designed that.Again can be in the state of cooling, air inlet is because cold But evaporation is made to expect to form solid-state, achievees the purpose that sealing, and when crucible carries out filler operation, the both sides of cause due to broken sky Pressure differential makes self-styled sealing valve have better seal effect.
Self-styled sealed valve body material is the easy heat conduction of red copper, and along 24 groups of cooling tube 7c of annular spread, being so designed that can be to certainly Envelope valve body is quickly and effectively cooled down.Cooling tube outer end is equipped with safety valve 7d, is so designed that not enable in self-styled sealing valve When, there are one safe releases for the pressure generated inside heating status, cooling water pipe due to expansion.It ensure that is used Security.
The nozzle uses same connection diameter different-diameter outlet mode, facilitates later stage various technique adjustments, preferably Improve the large-area uniformity problem of evaporation coating.
Valve between cone valve and crucible using self-styled sealing means, perfectly solve under high temperature tradition ORING because Leakage caused by poorly sealed and problem of aging, because this position of cone valve is in the point that heating operates repeatedly with cooling, So the easy aging of traditional butyronitrile sealing ring, cracking cause gas leakage.Because this position of cone valve is in heating with cooling down repeatedly The point of operation, so the easy aging of traditional butyronitrile sealing ring, cracking cause gas leakage.
3rd, heating component is distributed between crucible ectonexine, between gas pipeline and the ectonexine of crucible by exhaust pipe into Row connection, switch control is carried out by valve, and aspiration pump, one end connection nitrogen supply (NS) system are connected by three-way connection one end.
As an optimization, crucible uses double layer design, and outside uses water-cooling pattern, can be carried out when needs are shut down and are reloaded It is quickly cooled down, while it is to vacuumize state that double-layer inner, which just makes during operation, can be carried out quickly by being passed through nitrogen when shutdown Cooling, saving is reloaded the time, and ensure that the safety problem of crucible in special circumstances.
It designs as an optimization, crucible is designed using twoport, is made feeding mouth and evaporation gas outlet different position, is so designed that and removes Convenient for addition raw material, the sealing effect of gas outlet and feeding mouth is also ensured.
It designing as an optimization, appendix back segment B is in a manner that three sections of heating measure control respectively, with Resistant heating, Intermediate one section of heater strip length accounts for integrated piping length 3/5, and both ends heater strip length respectively accounts for total pipeline length 1/5, it is so designed that About each section temperature and evaporation rate can be preferably controlled in late stage process adjustment, preferably ensure that large area thin evaporated film Homogeneity question.
It designs as an optimization, gas pipeline is so designed that all using double-layer structure, and vacuumized in normal use The sealing security performance of appendix can preferably be improved.And heat radiation is reduced, it is energy saving.
During present invention normal work, evaporation raw material is put into crucible, and crucible is heated by heating component, raw material evaporation By gas pipeline and front end nozzle after into gas, it is agglomerated to formation film on the relatively low substrate of temperature and reaches deposition purpose.
Vaporizing-source system A raw materials evaporate, and close cone valve, self-styled sealed valve body is cooled down, at this time evaporation material It is set in self-styled sealed valve body passage when being cooled, when in certain time, after self-styled sealed valve body passage is fully sealed, closing Crucible heating component opens vaporizing-source system B and continues hydatogenesis progress continuous production.
Nitrogen is passed through between the crucible ectonexine of vaporizing-source system A to be cooled down within five minutes, is then evacuated, then qi of chong channel ascending adversely, it takes out Gas so cycles, and until crucible temperature is less than 30 degrees Celsius, opening crucible feeding mouth is filled raw material operation, has filled Finish, seal feeding mouth, to being vacuumized between crucible ectonexine, pumping half an hour, heated, it is stand-by, wait evaporation Source system B, evaporates, switches over, to achieve the purpose that continuous coating produces.
The above is only the preferred embodiment of this patent, it is noted that for the ordinary skill people of the art For member, on the premise of the art of this patent principle is not departed from, several improvement and replacement can also be made, these improve and replace Also it should be regarded as the protection domain of this patent.
