    • Provided is a protection film bonding method and a protection film bonding apparatus that improves productivity for bonding the protection film onto one surface of a silicon wafer. A carrier film is separated from a three-layer film having a reinforcement film, and is provided on front and rear surfaces of a protection film, to provide a two-layer film. This two-layer film is bonded onto the front surface of the silicon wafer, the reinforcement film is removed from the two-layer film and the protection film is trimmed. An apparatus consists of a supply unit, separation and take-up unit that separates the carrier film from the three-layer film, an assigning and separation unit, a joint unit that joins the two-layer film onto the silicon wafer, and a peel-off unit, that removes the reinforcement film while separating it from the two-layer film.
    • 提供了一种保护膜接合方法和保护膜接合装置,其提高了将保护膜接合到硅晶片的一个表面上的生产率。 将载体膜与具有加强膜的三层膜分离,并且设置在保护膜的前表面和后表面上,以提供双层膜。 将该双层膜粘合到硅晶片的正面上,从双层膜除去加强膜,并修整保护膜。 一种装置包括供给单元,将载体膜与三层膜分离的分离和卷取单元,分配和分离单元,将两层膜连接到硅晶片上的接合单元和剥离层 该单元在将其从两层膜分离时除去加强膜。

    • A trimming method and a trimmer capable of ensuring trimming a protection film which protects a silicon wafer and making a cut end of the protection film obtained by trimming neat, are provided. If a laser beam L is applied to the strip protection film 3 bonded onto the silicon wafer 1 to trim the protection film to have a predetermined size and a predetermined shape, an intake flow V such as an air curtain flow is applied to the protection film 3. A trimmer used to execute this method consists of a table 2 on which the silicon wafer 1 is mounted, an assigning and separation unit D for bonding the strip protection film 3 onto the silicon wafer 1, a laser beam unit G provided above the table for forming a cut 28 into the protection film 3 along a peripheral surface 1a of the silicon wafer 1, and an intake unit Av provided below the table for applying an intake flow V to a lower surface of the protection film 3 along the peripheral surface 1a.
    • 提供了一种修整方法和修剪器,其能够确保修整保护硅片的保护膜并且通过修整整齐地获得保护膜的切割端。 如果将激光束L施加到接合到硅晶片1上的带状保护膜3以将保护膜修剪成具有预定尺寸和预定形状,则将诸如气帘流的进气流V施加到保护膜 用于执行该方法的修剪器包括安装硅晶片1的工作台2,用于将条形保护膜3接合到硅晶片1上的分配单元D,设置在硅晶片1上方的激光束单元G 沿着硅晶片1的周面1a形成保护膜3的切口28的工作台,以及设置在工作台下方的进气单元Av,用于沿保护膜3的周面施加进气流V到下表面 1a。
