此外, 在本发明的描述中, 除非另有说明, "多个" 的含义是两个或两 个以上。 下面参考附图描述本发明实施例的腔室装置。
根据本发明实施例的腔室装置, 包括腔室本体 3、 加热部件 11、 支承台 5、 匀热板 13、 和透明介质窗 12。
具体而言, 腔室本体 3围绕形成处理腔室 8, 即腔室本体 3内限定有处 理腔室 8。
透明介质窗 12设在处理腔室 8内, 并且透明介质窗 12的外周沿与腔室 本体 3的内周壁相连, 以将处理腔室 8隔成上部腔室和下部腔室。 加热部件 11设在上部腔室内的顶部。 支承台 5设在下部腔室内用于支撑基片 4, 并且 支承台 5的上表面与加热部件 11相对,基片 4置于支承台 5的上表面。 匀热 板 13设在下部腔室内且位于支承台 5的上方, 即, 匀热板 13位于加热部件 11与基片 4之间。
可以理解的是, 透明介质窗 12的外周沿可以与腔室本体 3的内周壁之 间气密地相连, 由此, 在透明介质窗 12存在的情况下, 可以使加热部件 11 处于大气环境中(即上部腔室可以与大气连通), 而下部腔室与外界大气相隔 绝, 以在下部腔室内对基片 4进行处理。 其中, 从光透过率、 导热性能、 成 本等考虑, 优选釆用石英窗作为该透明介质窗 12。
可以理解的是, 关于勾热板 13在处理腔室 8内的具体安装方式没有特 别要求, 可以釆用任意安装方式, 只要可以使匀热板 13 安装在处理腔室 8 内即可。
根据本发明上述实施例的腔室装置,通过设置在加热部件 11与支承台 5 之间 (即, 设置在加热部件 11与基片 4之间) 的匀热板 13 , 可以将由加热 部件 11产生的热量均勾化后再通过热辐射、 热对流等方式传导给基片 4, 以 对基片 4进行加热, 从而解决了由于加热灯离散配置所导致的加热均匀性较 差的问题, 进而实现对基片 4的均匀加热。 根据本发明的一个实施例,支承台 5设有用于加热基片 4的底部加热器。 通过底部加热器和加热部件 11同时工作来对基片 4进行加热,可以进一步提 高腔室装置的加热效率, 从而提高基片 4的升温速率。 在本发明的一些实施 例中, 如图 1所示, 所述底部加热器为设在支^ ^台 5内的加热丝 6。 可以理 解的是, 本发明中的内部设置有加热丝 6的支承台 5的作用实际上类似于内 设有加热器的静电卡盘、 机械卡盘以及压差卡盘。
根据本发明的一个实施例, 匀热板 13 由陶瓷或石墨材料制成且具有预 定的黑度。 由此, 可以提高匀热板 13的匀热效果, 从而可以进一步改善基片 4 的处理效果。 其中, 黑度是指在一定温度下, 灰体的辐射能力与同温度下 黑体的辐射能力之比。在实际应用中,可以在匀热板 13的加工制作过程中基 于所釆用的材质、 添加剂等具体情况来得到预定黑度的勾热板 13。
根据本发明的一个实施例, 腔室本体 3的顶端敞开且由设在腔室本体 3 的顶端的反射板 2封闭。 借助该反射板 2, 可以将加热部件 11发出的光朝向 处理腔室 8内反射, 以对基片 4进行加热。 因此, 设置该反射板 2会有利于 提高腔室装置的加热效率。
根据本发明的一个实施例, 加热部件 11 为加热灯。 所述加热灯为环形 加热灯, 包括内环加热灯 15(如图 1所示, 内环加热灯 15是位于处理腔室 8 中心区域的加热灯, 且沿处理腔室 8的周向分布)和外环加热灯 16 (如图 1 所示,外环加热灯 16是位于处理腔室 8边缘区域的加热灯,且沿周向围绕内 环加热灯 15设置)。 由此,借助于上述加热部件 11将有利于进一步提高基片 4的温度均匀性。
进一步, 反射板 2的上表面上设有安装板 1 , 且二者紧密贴合, 而且, 安装板 1内设有用于流通冷却介质的第一冷却通道 17 ,用以对反射板 2进行 冷却, 以防止反射板 2过热, 从而确保反射板 2处于安全温度范围内。 此外 , 加热灯通过灯座 7安装在安装板 1上, 灯座 7安装在安装板 1的上表面上。
更进一步地, 安装板 1上可以设有用于保护灯座 7的保护罩 18。 由此, 可以避免发生因操作者接触到灯座 7而引起的事故, 从而有利于提高操作安 全性。
根据本发明的一个实施例, 腔室装置还包括屏蔽件 10, 屏蔽件 10与腔 室本体 3的顶端相连且沿腔室本体 3的内周壁向下延伸并环绕着腔室本体 3 的内周壁, 以避免腔室本体 3过热。
进一步, 屏蔽件 10内设有用于流通冷却介质的第二冷却通道 9。 由此, 可以通过冷却介质 (例如水、 油、 气体等)冷却腔室本体 3以避免其过热。 具有该屏蔽件 10的腔室装置,其防止腔室本体 3过热的效果更好,且结构简 单。
需要理解的是, 第一冷却通道 17和第二冷却通道 9中所流通的冷却介 质既可以相同也可以不同。
在本发明的一些实施例中, 屏蔽件 10 包括筒体和从所述筒体上端沿径 向延伸出的凸缘, 其中所述凸缘与腔室本体 3的顶端相连且所述筒体沿腔室 本体 3的内周壁向下延伸, 反射板 2安装在所述凸缘的上端面。 该腔室装置 结构简单,便于安装。 在此情况下, 石英窗 12的外周沿可以与所述筒体的内 周壁相连。
下面描述根据本发明实施例的基片处理设备。根据本发明实施例的基片 处理设备包括上述任一实施例所述的腔室装置。 根据本发明实施例的基片处 理设备的其他部分和功能对于本领域普通技术人员来说是已知的, 在此不再 赘述。
可选地, 所述基片处理设备为物理气相沉积设备。 进一步, 所述腔室装 置为所述物理气相沉积设备中的去气腔室。
根据本发明实施例的基片处理设备, 由于釆用了根据本发明实施例的腔 室装置, 因此具有基片处理效果好的优点。
下面以所述腔室装置作为去气腔室装置为例描述根据本发明一个实施 例的基片去气处理过程。 首先, 将基片 4放置到处理腔室 8内的支承台 5上。
接着, 通过加热部件 11加热匀热板 13 , 从而间接地对支承台 5上的基 片 4进行加热, 并通过调节加热部件 11的加热功率使得加热温度在 350 °C左 右。
上述基片的去气处理过程具有加热效率高、 加热均勾、 去气效果好等优 点。
