    • A dispersion plate for evenly flowing at low pressure into a processing chamber vaporized material, such as a tungsten compound for deposition of metal layers onto a semiconductor, has a disc-like body with a center axis, an input face and an output face. The dispersion plate has a cup-like entrance along the center axis in its input face for receiving a stream of vaporized material and a plurality of passages for flow of vapor with each passage having a length and a diameter and extending radially from the entrance like the spokes of a wheel at inclined angles relative to the center axis from the input face to the output face. Two annular grooves are cut into the output face and intersect with the respective ends of the passages. The plate has a center hole with a flared diameter extending along the center axis from the entrance in the input face to the output face. The hole and plurality of passages are designed to have sufficiently large diameters so as to keep pressure drops low with respect to vapor flowing through the plate.

    • A substrate support having a removable edge ring, which is made of a material having a lower coefficient of thermal expansion (CTE), than that of the substrate support is provided. The edge ring and the substrate support are configured for pin and slot coupling. Specifically, either the edge ring, or the substrate support comprises a plurality of pins, and the other of the edge ring or the substrate support comprises a plurality of hollow regions or slots in which the pins may be inserted. The slots are at least as wide as a corresponding one of the plurality of pins and extend in the direction in which the substrate support expands and contracts during thermal cycling. Each of the slots extends a length which is sufficient to compensate for the difference between the CTE of the substrate support and the CTE of the edge ring, over the range of process temperatures to which the apparatus is exposed. Preferably the susceptor is made of aluminum, and the edge ring is made of ceramic. A restrictor gap may be defined between a surface of the substrate support and a surface of the purge ring so as to restrict a volume of purge gas flowing to an edge of a substrate positioned on the substrate support. The purge gas delivery channel may have an exposed outlet and may be upwardly angled to facilitate cleaning.
    • 提供了一种具有可移除的边缘环的衬底支撑件,其由具有比衬底支撑件的热膨胀系数(CTE)低的材料制成。 边缘环和基板支撑件配置为销和槽联接。 具体来说,边缘环或衬底支撑件包括多个销,并且边缘环或衬底支撑件中的另一个包括可以插入销的多个中空区域或狭槽。 所述槽至少与所述多个销中相应的销一样宽,并且在所述基板支撑件在热循环期间膨胀和收缩的方向上延伸。 每个狭槽的长度足以补偿基板支撑件的CTE与边缘环的CTE之间的差异,在该设备暴露于该处理温度的范围内。 优选地,基座由铝制成,并且边缘环由陶瓷制成。 限定器间隙可以限定在衬底支撑件的表面和净化环的表面之间,以便限制流过位于衬底支撑件上的衬底的边缘的吹扫气体的体积。 净化气体输送通道可以具有暴露的出口并且可以向上成角度以便于清洁。

    • The present invention provides exemplary apparatus and methods for processing substrates and for ensuring purge gases reach the substrate edge, including edges of JMF type wafers, to help prevent unwanted deposition thereon. One embodiment provides an apparatus for processing substrates which includes a chamber and a substrate support (13) disposed in the chamber. An edge ring (15) is disposed on the substrate support. The edge ring has a lip portion (30) which at least partially overhangs an upper surface (36) of the substrate support to define a gap (29) between the lip portion and the upper surface. In this manner, the edge ring is designed to form a gap which properly directs purge gases to edges of the substrate, including JMF type substrates.

    • A plasma reaction chamber particularly suited for plasma-enhance chemical vapor deposition of titanium using TiCl.sub.4 as the precursor. The reactor includes a perforated showerhead faceplate and a perforated blocker plate within the showerhead to evenly distribute the atomized TiCl.sub.4. Both the showerhead faceplate and the blocker plate are made of solid nickel. RF power is applied between the showerhead faceplate and the heater pedestal supporting the wafer to excite the processing gas into a plasma. A shield ring is set on the periphery of the heater pedestal to confine the plasma to the processing region above the wafer. The shield ring is supported on the heater pedestal by a downwardly descending ridge, thereby minimizing thermal flow. The shield ring also protects the periphery of the top surface of the heater pedestal not covered by the wafer. An isolator electrically insulates the RF-driven showerhead from the chamber body and is disposed generally above the shield ring. The bottom of the isolator and the top of the shield ring are similarly curved with a nearly constant gap between them. The small gap creates a flow choke between the processing region and an annular pumping channel. The curve of the gap prevents the plasma from extending into the pumping channel. The bottom of the chamber below the heater pedestal is covered with a quartz thermal shield insert to reduce the flow of heat to the chamber wall. A lift ring for raising lift pins selectively lifting the wafer is also composed of quartz.
    • 一种等离子体反应室,特别适用于使用TiCl4作为前体的等离子体增强钛的化学气相沉积。 反应器包括穿孔淋浴头面板和淋浴器内的穿孔阻塞板,以均匀分布雾化的TiCl4。 喷头面板和阻挡板均由固体镍制成。 在喷头面板和支撑晶片的加热器基座之间施加RF功率以将处理气体激发成等离子体。 屏蔽环设置在加热器基座的周边上,以将等离子体限制在晶片上方的处理区域。 屏蔽环通过向下的下降脊支撑在加热器底座上,从而最小化热流。 屏蔽环还保护未被晶片覆盖的加热器基座的顶表面的周边。 隔离器将RF驱动的喷头与室主体电绝缘并且大致设置在屏蔽环的上方。 隔离器的底部和屏蔽环的顶部类似地弯曲,它们之间具有几乎恒定的间隙。 小间隙在处理区域和环形泵送通道之间产生流动扼流圈。 间隙的曲线阻止等离子体延伸到泵送通道中。 在加热器底座下面的腔室的底部覆盖有石英热屏蔽插入件,以减少到室壁的热量流动。 用于升高提升针的提升环选择性地提升晶片也由石英组成。
