    • Semiconductor processing equipment that has increased efficiency, throughput, and stability, as well as reduced operating cost, footprint, and faceprint is provided. Other than during deposition, the atmosphere of both the reaction chamber and the transfer chamber are evacuated using the transfer chamber exhaust port, which is located below the surface of the semiconductor wafer. This configuration prevents particles generated during wafer transfer or during deposition from adhering to the surface of the semiconductor wafer. Additionally, by introducing a purge gas into the transfer chamber during deposition, and by using an insulation separating plate 34, the atmospheres of the transfer and reaction chambers can be effectively isolated from each other, thereby preventing deposition on the walls and components of the transfer chamber. Finally, the configuration described herein permits a wafer buffer mechanism to be used with the semiconductor processing equipment, thereby further increasing throughput and efficiency.
    • 提供了提高效率,吞吐量和稳定性以及降低运营成本,占地面积和面部印刷的半导体处理设备。 除了沉积之外,使用位于半导体晶片表面下方的转移室排气口将反应室和转移室的气氛抽真空。 这种构造防止在晶片转移期间或在沉积期间产生的颗粒粘附到半导体晶片的表面。 此外,通过在沉积期间将吹扫气体引入转移室,并且通过使用绝缘分隔板34,可以有效地将转移室和反应室的气氛彼此隔离,从而防止沉积在转移的壁和组分上 房间。 最后,本文描述的配置允许晶片缓冲机构与半导体处理设备一起使用,从而进一步提高吞吐量和效率。
