【0009】 同図に示す半導体製造装置は、シ−ト(4)上のペレット取出しポジジョンと リ−ドフレ−ム(6)上のペレット供給ポジションの間の、所定の移動経路Cを 往復移動する吸着コレット(2)に適用したものである。この装置は、吸着コレ ット(2)の先端のペレット吸着部(3)の移動経路Cの水平な経路途中にブラ シ(8)を配置している。ブラシ(8)は、例えば回転ブラシであり、真空吸引 ポンプ(9)に直結された上下動可能な吸引ダクト(10)の上端開口に収納され る。ブラシ(8)は吸引ダクト(10)と共に所定の位置まで上昇すると、ブラシ (8)の上部が移動経路Cに達し、ブラシ(8)は吸引ダクト(10)と共に下降 すると、移動経路Cから外れる。吸引ダクト(10)はブラシ(8)の周辺を囲い 、後述するようにブラシ(8)が吸着コレット(2)に付着した異物を剥脱させ ると、この異物を真空吸引して排除する。[0009] The semiconductor manufacturing equipment shown in the figure has a pellet take-out position on the sheet (4) and A predetermined movement path C between pellet supply positions on the lead frame (6) is This is applied to a suction collet (2) that moves back and forth. This device is a suction collector. There is a brush on the horizontal path of the movement path C of the pellet suction part (3) at the tip of the pellet (2). Shi (8) is placed. The brush (8) is, for example, a rotating brush, and is a vacuum suction brush. It is housed in the upper end opening of a vertically movable suction duct (10) that is directly connected to the pump (9). Ru. When the brush (8) rises together with the suction duct (10) to a predetermined position, the brush (8) The upper part of (8) reaches the moving path C, and the brush (8) descends together with the suction duct (10). Then, it deviates from the moving route C. The suction duct (10) surrounds the brush (8). As will be described later, the brush (8) removes foreign matter adhering to the suction collet (2).

When moving on the return path B, the brush (8) rises to the upper limit position and rotates. . While the suction collet (2) is moving on the horizontal return path B, the pellet suction part (3) crosses the top of the rotating brush (8), and during this time the tip of the brush (8) touches the pellet. Rub the pellet adsorption part (3) to peel off foreign matter adhering to the pellet adsorption part (3). stripping The removed foreign matter is sucked into the suction duct (10) and is not scattered around. Bu The suction collet (2) that has passed through the rasp (8) further moves on the return path B and is attached to the sheet. (4) Take out the next semiconductor pellet (1) above. Below, the above operation is repeated. Each time the suction collet (2) moves on the return path B, the brush (8) Receive treatment to remove foreign matter.

【0012】 尚、ブラシ(8)の動作は上記例に限らず、吸着コレット(2)の往路A、復 路Bの両方で吸着コレット(2)にブラシ(8)を当てるようにしてもよい。ま た、ブラシ(8)を回転させながら、所定区間だけ吸着コレット(2)に当てた まま吸着コレット(2)と同時進行させて、ブラシ(8)と吸着コレット(2) の接触時間を増大させて、異物除去をより効果的ならしめてもよい。0012 In addition, the operation of the brush (8) is not limited to the above example, and the movement of the suction collet (2) is The brush (8) may be applied to the suction collet (2) on both paths B. Ma In addition, while rotating the brush (8), the brush (8) was applied to the suction collet (2) only in a predetermined section. At the same time as the suction collet (2), brush (8) and suction collet (2) The contact time may be increased to make foreign material removal more effective.
