    • A photoresist mask removing method for effectively removing polymers produced as by-products during etching of a metal layer includes processing the polymers prior to removal to facilitate removal thereof. To remove the photoresist mask remaining on a semiconductor substrate after the metal layer is dry-etched in an etching chamber, the semiconductor substrate is preferably conveyed from the etching chamber to an ashing chamber without vacuum break. The semiconductor substrate is pretreated by supplying N2 gas into the ashing chamber under the vacuum state without applying RF power to the ashing chamber to blow the N2 gas on the semiconductor substrate heated up to a predetermined temperature. This pretreatment modifies the polymer by-products to facilitate removal thereof during ashing. The photoresist mask and the polymer by-products are removed by ashing in the ashing chamber.
    • 用于有效去除在金属层蚀刻期间作为副产物生产的聚合物的光致抗蚀剂掩模去除方法包括在除去之前加工聚合物以便于其去除。 为了在蚀刻室中干蚀刻金属层之后去除保留在半导体衬底上的光致抗蚀剂掩模,半导体衬底优选地从蚀刻室传送到灰化室而没有真空断裂。 通过在真空状态下将氮气供给到灰化室中而对灰化室施加RF功率以将加热到预定温度的半导体衬底上的N 2气吹入半导体衬底来预处理。 该预处理改变了聚合物副产物,以便在灰化期间将其去除。 光致抗蚀剂掩模和聚合物副产物通过灰化室中的灰化除去。

    • A multiple reaction chamber system includes a transfer chamber, a load lock chamber connected to the transfer chamber, and a plurality of reaction chambers connected to the transfer chamber. An alignment chamber is connected to the transfer chamber, disposed along a path of wafer transfer from the load lock chamber to the plurality of reaction chambers, and includes a wafer aligner. A wafer recognition, disposed along a post-aligner portion of the path of wafer transfer system, recognizes an identification code of an individual wafer. A controlling system is in data communication with the wafer recognition system for selecting a selected chamber of the plurality of reaction chambers into which the individual wafer is to be transferred. Because individual wafers can be associated with each reaction chamber, a defective reaction chamber can be identified immediately and its use discontinued so that unproductive operations can be eliminated.
    • 多反应室系统包括传送室,连接到传送室的负载锁定室和连接到传送室的多个反应室。 对准室连接到传送室,沿着晶片从负载锁定室传递到多个反应室的路径设置,并且包括晶片对准器。 沿着晶片传送系统的路径的对准后部分布置的晶片识别识别单个晶片的识别码。 控制系统与晶片识别系统进行数据通信,用于选择要转移单个晶片的多个反应室的选定室。 因为单个晶片可以与每个反应室相关联,所以可以立即识别有缺陷的反应室,并且其使用停止,从而可以消除非生产性操作。

    • A communications equipment housing may be constructed using an upper plate, four vertical members extending downward from the four corners of the upper plate and attach to a lower plate. A front side plate and a rear side plate are attached to the sides of the housing and two lateral side plates are installed on the sides between the front side plate and the rear side plate. Both lateral sides are composed of two main lateral side plates and an auxiliary lateral side plate that is located between the two main lateral side plates. An female groove is formed along an edge of each main lateral side plate in a direction perpendicular to the planes of the top and bottom plates. The auxiliary lateral side plate has projecting male protrusions formed along two lateral edges of the auxiliary plate in a direction perpendicular to the planes of the top and bottom plate. A lateral side plate for the housing is assembled by tightly engaging the male protrusions of the auxiliary lateral side plate into the female grooves of the main lateral side plates. This allows for the simple adjustment of the housing to accommodate electronic components of greater number or size.
    • 通信设备壳体可以使用上板构造,四个垂直构件从上板的四个角向下延伸并附接到下板。 前侧板和后侧板安装在壳体的侧面,并且两个侧面板安装在前侧板和后侧板之间的侧面上。 两个横向侧面由位于两个主侧面板之间的两个主横向侧板和辅助横向侧板组成。 在每个主侧板的边缘沿垂直于顶板和底板的平面的方向形成阴凹槽。 辅助侧面板具有沿着与顶板和底板的平面垂直的方向沿着辅助板的两个侧边缘形成的突出的阳突起。 用于壳体的侧面侧板通过将辅助侧面板的凸形凸起紧密地接合到主侧面板的凹槽中来组装。 这允许简单地调整壳体以容纳更大数量或尺寸的电子部件。
