    • A batch of wafer substrates is provided with each wafer substrate having a surface. Each surface is coated with a layer of material applied simultaneously to the surface of each of the batch of wafer substrates. The layer of material is applied to a thickness that varies less than four thickness percent across the surface and exclusive of an edge boundary and having a wafer-to-wafer thickness variation of less than three percent. The layer of material so applied is a silicon oxide, silicon nitride or silicon oxynitride with the layer of material being devoid of carbon and chlorine. Formation of silicon oxide or a silicon oxynitride requires the inclusion of a co-reactant. Silicon nitride is also formed with the inclusion of a nitrification co-reactant. A process for forming such a batch of wafer substrates involves feeding the precursor into a reactor containing a batch of wafer substrates and reacting the precursor at a wafer substrate temperature, total pressure, and precursor flow rate sufficient to create such a layer of material. The delivery of a precursor and co-reactant as needed through vertical tube injectors having multiple orifices with at least one orifice in registry with each of the batch of wafer substrates and exit slits within the reactor to create flow across the surface of each of the wafer substrates in the batch provides the within- wafer and wafer-to-wafer uniformity.
    • 一批晶片基板设置有每个晶片基板具有表面。 每个表面涂覆有同时施加到每批晶片衬底的表面的一层材料。 该材料层被施加到在整个表面上变化小于四个厚度百分比的厚度,而不是边缘边界,并且晶片到晶片的厚度变化小于3%。 如此施加的材料层是氧化硅,氮化硅或氮氧化硅,其中该材料层不含碳和氯。 氧化硅或氮氧化硅的形成需要包含共反应物。 氮化氮也通过包含硝化共反应物形成。 用于形成这样一批晶片衬底的方法包括将前体进料到含有一批晶片衬底的反应器中,并在足以产生这种材料层的晶片衬底温度,总压力和前体流速下使前体反应。 根据需要通过具有多个孔的垂直管注射器输送前体和共反应物,其中至少一个孔与反应器内的每批晶片基板和出口狭缝对齐,以产生跨过每个晶片的表面的流动 该批次中的基板提供了晶片内和晶片与晶片的均匀性。
