Description

一种真空离子溅镀靶材装置 技术领域
本发明涉及真空离子溅镀领域,特别涉及一种真空离子溅镀靶材装置。
背景技术
在现有技术中,利用真空溅镀的工作原理如下:主要是利用辉光放电(glow discharge)将氩气(Ar)离子撞击靶材(target)表面,靶材的原子被弹出而堆积在基板表面形成薄膜。溅镀薄膜的性质、均匀度都比蒸镀薄膜来的好,但是,镀膜速度却比蒸镀慢很多。一般金属镀膜大都采用直流溅镀,而不导电的陶磁材料则使用RF交流溅镀,基本的原理是在真空中利用辉光放电(glow discharge)将氩气(Ar)离子撞击靶材(target)表面,电浆中的阳离子会加速冲向作为被溅镀材的负电极表面,这个冲击将使靶材的物质飞出而沉积在基板上形成薄膜。
目前,真空溅镀的靶材形状通常呈矩形,而新型的溅镀设备几乎都使用强力磁铁将电子成螺旋状运动以加速靶材周围的氩气离子化,造成靶材与氩气离子间的撞击机率增加,提高溅镀速率,因此,被离子撞击的靶材表面会形成波浪形状,导致靶材的利用率相当低,一般只有15%左右,从而造成非常大的浪费。
如图1所示,真空溅镀的靶材形状呈矩形,被离子撞击的靶材表面会形成波浪形状,即图1中的阴影部分为靶材消耗的部分10,这样靶材的剩余部分则留下很多,即图1中的空白部分为靶材的剩余部分20,由图可看出,该矩形的靶材会造成非常大的浪费,导致靶材的利用率相当低。又如,当靶材剩余的某一部分接近铜背板时,即黑色部分为铜背板30,而靶材别的区域的剩余部分则留下很多,但还是需要报废该靶材,需要更换一个新的矩形靶材继续进行真空溅镀操作,从而造成非常大的浪费,导致靶材的利用率相当低。
故,有必要提出一种新的技术方案,以解决上述技术问题。

所述真空离子溅镀靶材装置包括:一靶材100、以及一背板200;其中,所述靶材100位于所述背板200上方。所述靶材100,用于在真空溅镀操作过程中,被离子撞击的所述靶材100表面的原子会被弹出而堆积在基板表面以形成薄膜;所述背板200,用于固定所述靶材100。

在本发明实施例中,所述靶材100为一体成型的结构,所述背板200也可以是一体成型的结构。这样的制造方式,既方便生产,同时也能够节省材料。
下面详细描述真空溅镀的工作原理。
在充入少量工艺气体的容纳空间内,当极间电压很小时,只有少量离子和电子存在,电流密度在10-15A/cm2数量极,当阴极(即靶材100)和阳极间电压增加时,带电粒子在电场的作用下加速运动,能量增加,与电极或中性气体原子相碰撞,产生更多的带电粒子,直至电流达到10-6A/cm2数量极,当电压再增加时,则会产生负阻效应,即“雪崩”现象。此时离子轰击阴极,击出阴极原子和二次电子,二次电子与中性原子碰撞,产生更多离子,此离子再轰击阴极,又产生二次电子,如此反复。当电流密度达到0.01A/cm2数量级左右时,电流将随电压的增加而增加,形成高密度等离子体的异常辉光放电,高能量的离子轰击阴极(即靶材100)产生溅射现象。溅射出来的高能量靶材粒子沉积到阳极玻璃(即基板)上,从而达到镀膜的目的。
在正交电磁场的束缚下,电子在向阳极运动的过程中做螺旋状运动,电子被正交电磁场束缚在靶材100附近,电离出更多的带正电的离子和电子。
磁控管产生磁场,由于磁场强度分布不同,所以产生的等离子体密度分布不同,进而溅射速度不同,最终在靶材100表面形成了波浪状起伏的形貌,正由于本发明实施例的靶材的形状设置为波浪形状,由于在真空溅镀操作过程中,被离子撞击的靶材表面会形成波浪形状,即消耗的靶材大致呈波浪形状。因此,将所述靶材的形状设置为波浪形状,所述靶材的利用率相当高,基本不会存在剩余的靶材,从而节省了成本。本发明实施例提供的波浪形状的靶材,有效解决了现有技术中存在的由于采用矩形靶材作为溅镀材料,会造成靶材的利用率低的问题。
请一并参阅图5、图6及图7,图5为本发明实施例二提供的靶材的结构示意图;图6为本发明实施例二提供的靶材溅镀前的形貌结构示意图;图7为本发明实施例二提供的靶材溅镀后的形貌结构示意图。为了便于说明,仅示出了与本发明实施例相关的部分。
所述真空离子溅镀靶材装置包括:一靶材101、以及一背板201;其中,所述靶材101位于所述背板201上方。所述靶材101,用于在真空溅镀操作过程中,被离子撞击的所述靶材101表面的原子会被弹出而堆积在基板表面以形成薄膜;所述背板201,用于固定所述靶材101。
在本发明实施例中,所述靶材101下表面呈W形状,所述背板201的上表面也呈W形状,W形状的所述靶材101与W形状的所述背板201匹配接触,以使所述靶材101和所述背板201紧密结合在一起。本实施例中,由于在真空溅镀操作过程中,被离子撞击的靶材101表面会形成波浪形状,即消耗的靶材101大致呈W形状。因此,将所述靶材101的形状设置为W形状,所述靶材101的利用率相当高,基本不会存在剩余的靶材101,从而节省了成本。
进一步的,W形状的所述靶材101内嵌于W形状的所述背板201处,以使所述靶材101和所述背板201紧密结合在一起。W形状的所述靶材101,由于两边的物质基本会同时消耗掉,而不会导致一边还余留有所述靶材101,从而提高了所述靶材的利用率。
作为本发明一优选实施例,所述靶材101上表面为平面,这样设计的好处是,被离子冲击使所述101靶材的物质飞出而沉积在基板上形成的薄膜会较均匀。
然而,可以理解的是,所述靶材101上表面也可以为非平面,例如凹凸不平的表面。
在本发明实施例中,所述靶材101的厚度以及大小均可根据实际消耗情况来自行设定。这样便可在一次的真空溅镀操作过程消耗掉所述靶材101,不会因为所述靶材101不够而中断真空溅镀操作,重新更换一个新的靶材,也不会因为重新更换的靶材消耗不完而导致浪费的问题。本发明实施例是根据一次真空溅镀操作所需的量来进行设置的,因此有效提高所述靶材101的利用率,从而达到基本无浪费的情况,节省了成本。
在本发明实施例中,所述背板201采用铜材料制成。然而,可以理解的是,也可以采用其他金属材料制成。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。

然而,可以理解的是,所述靶材101也可以为合金靶材,例如:铁钴靶FeCo、铝硅靶AlSi、钛硅靶TiSi、铬硅靶CrSi、锌铝靶ZnAl、钛锌靶材TiZn、钛铝靶TiAl、钛锆靶TiZr、钛硅靶TiSi、 钛镍靶TiNi、镍铬靶NiCr、镍铝靶NiAl、镍钒靶NiV、镍铁靶NiFe等。
在本发明实施例中,所述靶材101为一体成型的结构,所述背板201也可以是一体成型的结构。这样的制造方式,既方便生产,同时也能够节省材料。

综上所述,本发明实施例提供的真空离子溅镀靶材装置,其靶材的形状是根据磁场强度分布而进行设定,如通过将靶材的形状设置为波浪形状,如W型,由于在真空溅镀操作过程中,被离子撞击的靶材表面会形成波浪形状,即消耗的靶材大致呈波浪形状。因此,将所述靶材的形状设置为波浪形状,所述靶材的利用率相当高,基本不会存在剩余的靶材,从而节省了成本。本发明实施例提供的波浪形状的靶材,有效解决了现有技术中存在的由于采用矩形靶材作为溅镀材料,会造成靶材的利用率低的问题。
