    • Embodiments of the invention provide methods for forming a material on a substrate which includes exposing a plurality of substrates within a batch process chamber to a first oxidizing gas during a pretreatment process, exposing the substrates sequentially to a precursor and a second oxidizing gas during an ALD cycle and repeating the ALD cycle to form a material on the substrates. In a preferred example, a hafnium precursor is used during the ALD process to form a hafnium-containing material, such as hafnium oxide. In one example, the first and second oxidizing gases are the same oxidizing gases. In a preferred example, the first and second oxidizing gases are different oxidizing gases, such that the pretreatment process contains ozone and the ALD process contains water vapor.

    • A method and apparatus that is useful for forming a high quality gate dielectric layer in MOS TFT devices using a high density plasma oxidation (HDPO) process. The HDPO process forms a good interface and then a second layer, which has good bulk electrical properties, is deposited at a higher deposition rate over the HDPO layer. In one embodiment a thin HDPO process layer is formed over the channel, source and drain regions to form a high quality dielectric interface and then one or more dielectric layers are deposited on the HDPO layer to form a high quality gate dielectric layer. The HDPO process generally entails using an inductively and/or capacitively coupled RF energy transmitting device to generate and control the plasma generated over the surface of the substrate and injecting a gas containing an oxidizing source to grow the interfacial layer. A second dielectric layer may then be deposited on the surface of the substrate using a CVD or plasma enhanced CVD deposition process. Aspects of the present invention also provide a cluster tool that contains at least one specialized plasma processing chamber that is capable of depositing a high quality gate dielectric layer. The cluster tool is advantageous because it supports both the pre-processing steps, such as, preheating the substrate, pre-cleaning the surface of the substrate prior to processing, and cool down after processing, all in a single controlled environment.
    • 一种用于在使用高密度等离子体氧化(HDPO)工艺的MOS TFT器件中形成高质量栅极电介质层的方法和装置。 HDPO工艺形成良好的界面,然后在HDPO层上以更高的沉积速率沉积具有良好体积电特性的第二层。 在一个实施例中,在沟道,源极和漏极区域之上形成薄的HDPO处理层以形成高质量的电介质界面,然后在HDPO层上沉积一个或多个介电层以形成高质量的栅极电介质层。 HDPO工艺通常需要使用感应和/或电容耦合的RF能量传输装置来产生和控制在衬底的表面上产生的等离子体,并且注入含有氧化源的气体以生长界面层。 然后可以使用CVD或等离子体增强CVD沉积工艺将第二电介质层沉积在衬底的表面上。 本发明的方面还提供一种包含能够沉积高质量栅极电介质层的至少一个专用等离子体处理室的簇工具。 集群工具是有利的,因为它支持预处理步骤,例如预热衬底,在处理之前预清洁衬底的表面,以及在处理之后,在单个受控环境中冷却。

    • System for producing diffusion-inhibiting epitaxial semiconductor layers, by means of which thin diffusion-inhibiting, epitaxial semiconductor layers can be produced on large semiconductor substrates at a high throughput. The surfaces of the semiconductor substrates to be coated are first cleaned, and the substrates are then heated in a low pressure batch reactor to a first temperature (prebake temperature). The surfaces to be coated are next subjected to a hydrogen prebake operation at a first reactor pressure. In the next step the semiconductor substrates are heated in a low pressure hot or warm wall batch reactor to a second temperature (deposition temperature) lower than the first temperature, and after a condition of thermodynamic equilibrium is reached the diffusion-inhibiting semiconductor layers are deposited on the surfaces to be coated in a chemical gaseous deposition process (CVD) at a second reactor pressure higher than, equal to or lower than the first reactor pressure.
