Description
The vacuum-evaporation appts and one that the present invention relates to carry out vacuum-evaporation under lower temperature is used for the anti-deposition plate of vacuum-evaporation appts.
The vacuum-evaporation appts that forms a film on the surface of substrate (as a camera lens) generally includes a vacuum vessel and and is located at evaporation source in the vacuum vessel.Substrate is by an arch clamping device clamping, and this clamping device is removably mounted on evaporation source top in the vacuum vessel, thereby carries out vacuum-evaporation.In order to prevent that these directly are deposited on the inwall of vacuum vessel from the no show substrate of evaporation source or the evaporating particle of clamping device (as evaporation atom or vapor molecule), catch the anti-deposition plate of these evaporating particles along inwall being provided with of vacuum vessel.
Yet in the vacuum-evaporation appts of above-mentioned prior art, the evaporating particle of no show substrate or arch clamping device can be in the inwall deposition of broad area upper edge vacuum vessel as a film.Like this, in the time of in air leaking enters vacuum vessel, gas (mainly is H
2O) be attracted on the film.Radiant heat from evaporation source when film formation next time makes the gaseous emission that is adsorbed on the film enter vacuum vessel.As a result, the vacuum in the vacuum vessel is just unstable, and perhaps the surplus air mixture in the vacuum vessel changes, thereby the character of the film that forms changes.When carrying out vacuum-evaporation in heating evaporation source not or with lesser temps heating evaporation source (to form film on the plastic lens surface), the problem of adsorbed gas is clearly.Repeatedly repetition along with film forms and leaks constantly thicken along the sedimentary film of the inwall of vacuum vessel, and the quantity of adsorbed gas also increases.Correspondingly, after the firm honing of vacuum vessel and film be concatenated to form after between, the specific refractory power that is formed at on-chip film is different.As a result, film changes between every batch and every batch, and the quality instability.And, when when the sedimentary film of vacuum vessel inwall comes off, the dust and diffuse into vacuum vessel kicked up, and be deposited on the surface of substrate.So just cause defective.
In order to address the above problem, the honing that had proposed to shorten vacuum vessel is already dried at interval or to the vacuum vessel inwall.Yet these methods require to interrupt film and form operation in the long duration, and have reduced productivity.
The purpose of this invention is to provide a kind of vacuum-evaporation appts, it can prevent to launch the film quality that causes again and descend because of adsorbing the gas of vacuum vessel into, prevent the pollution in the vacuum vessel, and prevent the defective that causes in on-chip deposition because of dust, and provide a kind of anti-deposition plate that is used for vacuum-evaporation appts.
Vacuum-evaporation appts of the present invention comprises a vacuum vessel, and one is located at an evaporation source and the arch clamping device in the vacuum vessel, in order to clamping one substrate and be arranged on evaporation source top in the vacuum vessel.Vacuum vessel is divided into the part that a part and that comprises evaporation source comprises clamping device, and the position above evaporation source is formed with a hole.This hole is shaped like this, promptly when it and clamping device when evaporation source is seen clamping device overlapping.Be provided with a dismountable anti-deposition plate and arrive clamping device and substrates from these evaporating particles that pass the hole of evaporation source.
Anti-deposition plate of the present invention is removably mounted in the vacuum-evaporation appts, and this equipment comprises vacuum vessel, is located at evaporation source and arch clamping device in the vacuum vessel, in order to the clamping substrate and be located at evaporation source top in the vacuum vessel.Under anti-deposition plate was installed on situation in the vacuum-evaporation appts, vacuum vessel can be divided into the part and the part that comprises clamping device that comprise evaporation source.Above evaporation source, form porose.This hole is shaped like this, promptly when it and clamping device when evaporation source is seen clamping device overlapping.These evaporating particles that pass the hole from evaporation source arrive clamping device and substrate.
Because vacuum vessel is divided into evaporation source part and clamping device part, the hole is formed at the top of evaporation source, the hole be shaped so promptly when it and clamping device when evaporation source is seen clamping device overlapping, be provided with dismountable anti-deposition plate, so these evaporating particles that pass the hole of anti-deposition plate from evaporation source just arrive clamping device or substrate.On the other hand, if anti-deposition plate is not set, these evaporating particles of being stopped by anti-deposition plate can not be deposited on clamping device or the substrate, that is to say on the inwall that is deposited on vacuum vessel.By anti-deposition plate is set, prevented that thin film deposition is on the inwall above the anti-at least deposition plate of vacuum vessel, even and carry out vacuum-evaporation with lower temperature, also suppressed adsorbed gas and launched, so vacuum-evaporation is carried out in stable vacuum and gaseous mixture from the vacuum vessel inwall.In addition, because the film quantity that is deposited on the vacuum vessel inwall is few, come off and spread from inwall so prevented film, and the thin film deposition that has prevented to come off is on substrate.
Evaporating particle from evaporation source is launched in certain three-dimensional perspective that makes progress, and has only seldom part side direction or emission downwards.Like this, when anti-deposition plate was provided with near evaporation source, the evaporating particle of most of no show clamping devices or substrate just was deposited on the anti-deposition plate., just can form stay-in-grade film, and can between every batch, not change always to keep anti-deposition plate cleaning by the deposition plate of more relieving a garrison for every batch of vacuum-evaporation.When evaporation is (for example forming film on plastic lens) when carrying out under lower temperature, even close the evaporation source that anti-deposition plate is provided with prevents that the temperature rise of deposition plate does not constitute problem yet.
The shape of anti-deposition plate can be an Any shape, evaporating particle arrives except passing the hole of preventing deposition plate the vacuum vessel part that comprises clamping device like this, evaporating particle can not pass other zone, and it can extend to the side of evaporation source and is roughly parallel at the evaporating particle flow direction of lateral location from evaporation source.When anti-deposition plate extended to the evaporation source side, nearly all evaporating particle of no show clamping device or substrate can be bonded on the anti-deposition plate.Like this, by the deposition plate of in every batch, more relieving a garrison, can obtain the cleaning ambient in the vacuum vessel.
When one group of evaporation source is set, can be the anti-deposition plate that each evaporation source is provided with said structure in vacuum vessel.By for each evaporation source is provided with anti-deposition plate, when according to the evaporation source heating means, evaporating materials and shape thereof and evaporation is distributed not simultaneously, the interval between evaporation source and anti-deposition plate all can reach optimizing to each evaporation source.Be that the situation that one group of evaporation source is provided with a shared anti-deposition plate is compared, can prevent to be deposited on the inwall of vacuum vessel from the evaporating particle that evaporation source leaks by the hole.

Referring now to accompanying drawing, explain embodiments of the invention.
Fig. 1 is a longitudinal sectional view, shows the structure of first embodiment of vacuum-evaporation appts of the present invention; Fig. 2 is a longitudinal sectional view, shows the relation between the diameter in a interval between an anti-deposition plate and an evaporation source and a hole; Fig. 3 is the sectional view of the structure of vacuum-evaporation appts.
Vacuum-evaporation appts comprises the tubular vacuum vessel 1 that has connected evaporation unit (not shown) in the side of being generally, one is arranged on the evaporation source 3 at vacuum vessel 1 bottom centre place, with an arch clamping device 2, it is above with in the face of evaporation source 3 that it is removably mounted on the center of vacuum vessel 1.Clamping device 2 is used for clamping one substrate, as a plastic lens, makes it in the face of evaporation source 3.Because it is arcual, thus the particle that it can avoid evaporating pass clamping device 2 and be bonded on the top board of vacuum vessel 1, no matter and the position on clamping device 2 how, it keeps a constant distance basically from evaporation source 3.Substrate 8 be clamped on the internal surface of clamping device 2 and when its inboard when evaporation source 3 looks be a circular arc that limits by clamping device 2.On the other hand, evaporation source 3 has the recess of a clamping evaporating materials 9 at its top, and it produces the evaporating particle stream of an evaporating materials 9 by currently known methods such as electron beam or resistive heating in a given three-dimensional perspective, shown in arrow among Fig. 1.
One is installed on the top of a flashboard axis 10 in order to control from the flashboard 6 of the evaporating particle of evaporation source 3 stream, and extend this 10 bottom of passing vacuum vessel 1 rotationally and airtightly.When flashboard axis 10 rotated, flashboard 6 also alternately moved to one near evaporation source 3 and directly is in the position of evaporation source 3 tops and leaves a position that is located immediately at evaporation source 3 tops.
One anti-deposition plate 4 is removably mounted in the vacuum vessel 1 and above flashboard 6, vacuum vessel 1 is divided into a part and a part that comprises clamping device 2 that comprises evaporation source 3 by jaw 7.Anti-deposition plate 4 is plate-like pieces, and the heart has a circular hole 5 therein, and the periphery of anti-deposition plate 4 closely contacts with the inwall of vacuum vessel 1 basically.Hole 5 is shaped like this, and is promptly overlapping when it and clamping device when evaporation source 3 is seen clamping device 2, and equals from the three-dimensional perspective of the clamping device 2 of evaporation source 3 findings from the three-dimensional perspective in the hole 5 of evaporation source 3 findings.Anti-deposition plate 4 is positioned adjacent to evaporation source 3, just is deposited on from the evaporating particle except that the evaporating particle that is deposited on flashboard 6 or flashboard axis 10 of evaporation source 3 like this and prevents on the deposition plate 4 or pass hole 5.
Explain the relation between the diameter in the interval of 3 of anti-deposition plate 4 and evaporation sources and hole 5 referring now to Fig. 2.
If the evaporation area of evaporation source 3 (water surface of evaporation of the evaporating materials 9 of heating) can be counted as a point basically, equal from the three-dimensional perspective of evaporation source 3 being seen clamping devices 2 from the three-dimensional perspective in evaporation source 3 being seen holes 5, and satisfy following relation:
L/R＝h/φ
Wherein h is the evaporation area of evaporation source 3 and the interval between the anti-deposition plate 4, and φ is the diameter in hole 5, and R is the diameter of clamping device 2, and L is by the plane that limits bottom of clamping device 2 and the distance between the evaporation area.
In order to prevent thin film deposition on the inwall of vacuum vessel 1 by means of anti-deposition plate 4, the interval h between anti-deposition plate 4 and the evaporation source 3 should be as far as possible little, as long as it can not hinder the motion of flashboard 6.For example, anti-deposition plate 4 can be located immediately at the about 10-50mm in flashboard top.Because the evaporating particle stream from evaporation source 3 is uniform, and bigger density is arranged directly over evaporation source 3, so clamping device 2 be arranged on evaporation source 3 directly over, and the center in hole 5 preferably is positioned at and connects among the evaporation source 3 among the heart and clamping device 2 on the wire of the heart.For example, suppose L=600mm, R=500mm, and flashboard 6 is positioned at evaporation source top 80mm, h=100mm is about 83.3mm by must portal 5 diameter of above-mentioned formula so.
Explain the operation of vacuum-evaporation appts now.
Because the anti-deposition plate 4 that has a hole 5 is located at the top of evaporation source 3, so from the evaporating particle of evaporation source 3 or be deposited on the anti-deposition plate 4 or pass hole 5.Because hole 5 forms like this; promptly it and clamping device 2 are overlapping and equal from the three-dimensional perspective of evaporation source 3 being seen clamping devices 2 from the three-dimensional perspective in evaporation source 3 being seen holes 5 when evaporation source 3 is seen clamping device 2; so pass the evaporating particle or the arrival clamping device 2 in hole 5 or arrive the substrate that is clamped on the clamping device 2, on the surface of substrate 8, just form a film like this.Evaporating particle can not arrive the vacuum vessel inwall of anti-deposition plate 4 tops.
When on substrate 8, forming the film of pre-determined thickness, flashboard 6 is urged to off-position, and stops heating evaporation source 3, air is released into vacuum vessel 1, and takes out the clamping device 2 of tape base sheet 8 from vacuum vessel 1.Replace place where troops were originally stationed deposition plate 4 with a clean anti-deposition plate.When the film that carries out next batch forms operation, repeat above step.
In vacuum-evaporation, owing to adopted anti-deposition plate 4, at least prevented that thin film deposition is on the inwall of the above vacuum vessel 1 of anti-deposition plate, even and vacuum-evaporation is to carry out at low temperatures, also can suppress adsorbed gas emission on the wall within the vacuum vessel 1, vacuum-evaporation is just carried out in stable vacuum and gaseous mixture like this.Correspondingly, the variation on the performance of the film of formation is also suppressed in the difference batch.Owing to be deposited within the vacuum vessel 1 film on the wall almost is zero, just avoided film to come off and spread from inwall, and the thin film deposition that has prevented to come off is on substrate 8.Because the evaporating particle stream from evaporation source 3 makes progress, so the film that is deposited on the anti-vacuum vessel inwall of deposition plate below 4 is zero basically.Even there is depositing of thin film, because anti-deposition plate 4 has been arranged, the film that comes off also is difficult to arrive substrate 8.
In this vacuum evaporation equipment, anti-deposition plate not only extends above evaporation source, also extends to the side of evaporation source, and in lateral location, anti-deposition plate is parallel to the evaporating particle stream from evaporation source usually.Position up, anti-deposition plate are usually perpendicular to the evaporating particle stream from evaporation source.
Interval between evaporation source and anti-deposition plate preferably like this, the nearly all evaporating particle stream from evaporation source that does not promptly pass the hole all is deposited on the anti-deposition plate.Interval between anti-deposition plate and the flashboard preferably like this, i.e. vacuum vessel the off-position of flashboard can not arrive anti-deposition plate from the evaporating particle of evaporation source above.
Like this, flashboard 6 preferably is designed to satisfy and concern A＜B, and as shown in the figure, wherein A is the interval between anti-deposition plate 4 and the flashboard 6, and B is the distance between the end of the edge of opening (end face of anti-deposition plate 4) in hole 5 flashboard 6 extremely in the closed position.That is, flashboard 6 be preferably disposed on anti-deposition plate 4 near.
Explain the second embodiment of the present invention now.Fig. 5 is a longitudinal section, shows the structure of vacuum-evaporation appts in the present embodiment.
In the present embodiment, one group of evaporation source 13 is arranged on the bottom of vacuum vessel 11, and is provided with a shared anti-deposition plate 14 for these evaporation sources 13.Anti-deposition plate 14 has a sidewall 14a who extends downwards.Other parts are identical with the foregoing description 1.Evaporation source 13 can have different types as shown in the figure.Have one group of hole 15 that is used for one group of evaporation source 13 on the anti-deposition plate 14.Hole 15 is shaped like this, promptly sees that from corresponding evaporation source 13 clamping device 2 they and clamping device 2 are overlapping, and equals from the three-dimensional perspective of the clamping device 2 of corresponding evaporation source 13 findings from the three-dimensional perspective in the hole 15 of 13 tools of corresponding evaporation source.The sidewall 14a of anti-deposition plate 14 extends to the bottom of vacuum vessel 11 with the whole periphery of the side inwall of lower edge vacuum vessel at the horizontal component of anti-deposition plate 14.Like this, anti-deposition plate 14 is supported oneself by its sidewall 14a, and does not need jaw used among the embodiment 17.
In this vacuum evaporation equipment, owing to adopted sidewall 14a, be deposited on the sidewall 14a from the evaporating particle of evaporation source 13 sideward directed, prevented thin film deposition fully on wall within the vacuum vessel 11 below anti-deposition plate 14 horizontal components, and further reduced adsorbed gas.
Explain the third embodiment of the present invention now.Fig. 6 shows the sectional elevation of vacuum-evaporation appts of the present invention.In above-mentioned second embodiment, for the evaporation source group has adopted a shared anti-deposition plate, but in the present embodiment, for each evaporation source provides an anti-deposition plate, and vacuum vessel is divided into a part and a part that comprises clamping device that comprises evaporation source.
