升举板30大致上被设置成平行于基材支撑件表面14。 Lift plate 30 is disposed substantially parallel to the substrate support surface 14. 至少两调整构件34与一连接构件(例如一球形轴承)被耦接在介于升举板30与一参考表面36之间。 At least two adjustment members 34 and a connecting member (e.g., a spherical bearing) are coupled between the leveling plate 30 liters of between 36 and a reference surface. 在所显示的实施例中,参考表面36为腔室12的底部表面36,但是其可以为相对于面板16被固定住的其他表面。 In the embodiment shown, the reference surface 36 for the bottom surface 36 of the chamber 12, but it may be fixed with respect to the other surface of the panel 16 is live. 参考表面36可以大致上平行于面板16。 Reference surface 36 may be substantially parallel to the panel 16. 调整构件34是在数个调整位置40处被连接至升举板30,其中该些调整位置40是分布于升举板30上。 Adjustment member 34 is adjusted in a number of positions 40 is connected to the lifting plate 30, wherein the plurality of adjustment points 40 is distributed in the lifting plate 30. 调整构件34是可以独立调整的以改变在调整位置40处升举板30与参考表面36之间的间距。 Adjustment member 34 can be independently adjusted to vary the position of 40 liters in the adjustment plate 30 and the lift 36 the spacing between the reference surface. 这会接着改变在数个对应调整位置42处介于基材支撑件表面14与面板16之间的间距,藉此调整了基材支撑件表面14相对于面板16的倾斜。 This would then change the number of adjustment positions corresponding to the spacing 42 between the surface of the substrate support member 14 and between panel 16, thereby adjusting the inclination of the panel 16 with respect to the substrate support surface 14. 在图1实施例中,基材支撑件表面14的对应调整位置42为大致上对齐于升举板30的调整位置40,这是因为升举板30是大致上平行于基材支撑件表面14。 In the embodiment of Figure 1, the substrate support member 42 to adjust the position corresponding to the surface substantially aligned with the leveling plate 40 to adjust the position 30 of 14, because the lifting plate 30 is substantially parallel to the surface of the substrate support member 14 . 在特定实施例中,对应调整位置42相对于基材支撑件表面14中心而均匀地分布于基材支撑件表面14周围。 In a particular embodiment, the adjustment of the position of the corresponding substrate support member 42 with respect to the center of the surface 14 uniformly distributed around the substrate support surface 14.

实验已经证明层次在一基材13上的沉积速率是与基材13及面板16之间的间距相关联,因此形成在基材13上层次的厚度均匀性可以通过改变基材支撑件表面14的倾斜来调整,其中基材13停置于该基材支撑件表面14上。 Experiments have shown that levels of deposition rate on a substrate 13 is the pitch associated with the substrate 13 and between panel 16, 13 thus formed on the substrate level by changing the thickness uniformity of the substrate support surface 14 to adjust the inclination, wherein the substrate 13 disposed in the substrate support member stop surface 14. 图4与图5是显示出两组试验的实验结果。 Figures 4 and 5 shows the experimental results of two experiments.

在图4中,改变基材与面板之间的间距而形成BPSG薄膜在基材上。 In Figure 4, changing the spacing between the substrate and the BPSG film is formed on the panel substrate. 薄膜是使用He、TEOS、TEB、TEPO作为制程气体于约550℃温度与约200托耳压力而被形成。 Film using He, TEOS, TEB, TEPO as process gases at a temperature of about 550 ℃ and about 200 Torr pressure is formed. 图4绘制出沉积速率(/min)与间距(mils)的关系图。 Figure 4 plotted deposition rate ( / min) and the pitch (mils) of the diagram. 当间距增加时,沉积速率降低约27.953/min,其为用以计算出对于特定制程的一关联因子的线的斜率。 When the distance increases, the deposition rate is reduced from about 27.953 / min, which is used to calculate the specific manufacturing process for a correlation factor of slope of the line.

在图5中,改变基材与面板之间的间距而形成BPSG薄膜在基材上。 In Figure 5, changing the spacing between the substrate and the panel is formed on the BPSG film on the substrate. 薄膜是使用He、TEOS、TEB、TEPO作为制程气体于约550℃温度与约200托耳压力而被形成。 Film using He, TEOS, TEB, TEPO as process gases at a temperature of about 550 ℃ and about 200 Torr pressure is formed. 当间距增加时,沉积速率降低约23.169/min,其为用以计算出对于特定制程的一关联因子的线的斜率。 When the distance increases, the deposition rate is reduced from about 23.169 / min, which is used to calculate the specific manufacturing process for a correlation factor of slope of the line. 图4与图5的相当小差异是归因于升举机构的可变性、液体流变化、实验室温度等等。 Figures 4 and 5 is relatively small differences due to the variability of the lifting mechanism, liquid flow variations, laboratory temperature and the like.

根据沉积速率与基材及面板之间的间距的关联,以下将描述三点计算倾斜程序(three point counter-tilt)以调成基材支撑件表面的倾斜而改善均匀性,其中该关联是被建立用于牵涉的特定形式制程。 According to the associated spacing between the substrate and the deposition rate with the panel, the following three points will be described inclination calculation program (three point counter-tilt) to tune into the inclined surface of the substrate support member while improving uniformity, wherein the association is established for the specific form of the process involved. 如图6的流程图100所示,在将基材支撑件定位于距离面板的一所希望间距之后,一层次形成于基材上(步骤102)。 Flow chart of FIG. 6, after the substrate support member positioned in a desired distance from the panel pitch, a hierarchy is formed on a substrate (step 102) 100. 在步骤104,量测层次厚度,其可以在原位完成。 In step 104, a thickness measurement level, which can be done in situ. 图7显示一厚度图90的范例,该厚度图具有49个点以产生在基材上该层次的一厚度曲线。 Figure 7 shows an example of a thickness map 90, the thickness map having 49 points to generate a thickness profile of the level on the substrate. 基材上三点92、94、96在位置上对应于升举板30上的三量测位置50以使用图3中测微计54来量测间距。 92,94, 96 at three points on the substrate corresponding to the position on the lifting plate 30 on the amount of the three measured position 50 in Figure 3 using 54 micrometer to measure pitch. 该三点92、94、96典型地为接近基材边缘,且角度上相对于基材中心而大致上均匀地相隔开。 The three 92,94,96 typically close to the edge of the substrate, and the angle relative to the center of the substrate and substantially evenly spaced apart. 例如,该三点92、94、96相对于基材中心隔开约120,且每一者距离基材边缘有小于基材半径的10%的距离。 For example, the three points 92, 94 spaced from the center with respect to the substrate of about 120 , and each has a radius of less than 10% of the distance from the base substrate edge.

请参阅图6,下一步骤106是计算该三点间的厚度差异。 See Figure 6, the next step is to calculate the thickness of 106 difference between the three points. 例如,点92是被选作为一参考位置,且计算参考点92与在剩下位置的其他点94、96之间的厚度差异。 For example, point 92 is selected as a reference position, and calculating the reference point 92 and the other difference in thickness between the points 94, 96 in the rest position. 在步骤108,厚度差异(点94与92之间及点96与92之间)通过沉积时间被分割以获得参考点92与剩下点94、96之间的沉积速率微分。 To obtain the reference point 92 and the remaining points 94, 96 between the deposition rate differential in step 108, the thickness differences (between the points 94 and 92 and between points 92 and 96) is divided by the deposition time. 一先前决定的关联因子接着被用来将沉积速率微分转换成在剩下点94、96处之间距调整以改善均匀性(步骤110)。 A previously determined correlation factor is then used to convert the deposition rate differential remaining at spaced points 94, 96 of the adjustment to improve the uniformity (step 110). 如果在剩下点的厚度大于在参考点92的厚度的话,则间距调整为正的以增加在剩下点处的基材支撑件与面板之间的间距。 If the point is greater than the thickness of the remaining thickness at the reference point 92, then the spacing adjustment is positive to increase the spacing between the remaining points of the substrate support member and the panel. 相反地,如果在剩下点的厚度小于在参考点92的厚度的话,则间距调整为负的以减少在剩下点处的基材支撑件与面板之间的间距。 Conversely, if the thickness of the remaining points of the reference point is less than the thickness at 92, then the spacing adjustment is negative to decrease the spacing between the remaining points of the substrate support member and the panel. 在步骤112,进行间距调整,且校正基材支撑件以对于所选择特定制程来形成改善均匀性的层次。 In step 112, where pitch adjustment and correction for the substrate support member to select a particular process to improve the uniformity of the formed layers.

关联因子正比于沉积速率对间距作图(如图4与图5)的斜率。 Correlation factor is proportional to the deposition rate of the pitch plotted (FIG. 4 and FIG. 5) of the slope. 亦即,关联因子正比于间距改变除以层次沉积厚度速率的比值。 That is, the correlation factor is proportional to the distance divided by the level of change in the ratio of the rate of deposition thickness. 典型地,关联因子将不等于斜率,但是将必须被修正以解释三点计算倾斜程序与间距调整之间的差异。 Typically, the association will not be equal to the slope factor, but it will have to be modified to account for three-point tilt calculate the difference between the program and the spacing adjustment. 为了获得图,基材向上或向下移动而不倾斜。 To obtain maps, substrate move up or down without tilting. 然而,在三点计算倾斜程序中,在剩下点的其一者的间距相对于参考点被调整以将基材倾斜。 However, in the three-point calculation tilt program, in the pitch of the remaining one of those points with respect to the reference point is adjusted to tilt the substrate. 因此,关联因子将等于一关联因子或常数乘以图斜率,其可以通过进行许多实验而经验性决定以获得关联因子而达到薄膜厚度均匀性。 Therefore, a correlation factor will equal or constant multiplying factor associated slope map, which can be carried out many experiments and empirical decided to get associated factor to achieve film thickness uniformity.

不同实验被进行以确定三点计算倾斜程序的重复性,以达到改善对于特定半导体制程形成在基材上层次的厚度均匀性。 Different experiments were performed to determine the three-point calculation procedure inclined repeatability, in order to achieve improved manufacturing process for a particular semiconductor substrate is formed at the level of thickness uniformity.
