    • The present invention relates to a head for a wafer polisher having a new structure capable of exactly recognizing a replacement time of a retainer ring. The head for a wafer polisher according to the present invention includes: a retainer ring (20) formed therein with a sensing hole (21) connected to a feed passage (16); a feed part connected to the feed passage (16) to supply high pressure air into the sensing hole (21); an atmospheric pressure measuring part (30) installed in the sensing hole (21) or the feed passage (16) to measure atmospheric pressure inside the sensing hole (21) or the feed passage (16); and a control unit (40) to receive a signal of the atmospheric pressure measuring part (30). A bottom end of the sensing hole (21) is extended to a preset limited abrasion height of the retainer (20). Accordingly, when the retainer ring (20) is worn out up to the preset limited abrasion height, a bottom end of the sensing hole (21) is open. Accordingly, the high pressure air supplied into the sensing hole (21) is discharged to the outside, and the internal atmosphere pressure of the sensing hole (21) is reduced. Unlike an existing head using the retainer ring (20) for a preset used time, since the control unit (40) receives a signal from the atmospheric pressure measuring part to confirm, the retainer ring (20) may be efficiently used.
    • 本发明涉及一种具有能够精确识别保持环更换时间的新结构的晶片抛光机头。 根据本发明的用于晶片抛光机的头部包括:形成在其中的保持环(20),其具有连接到进料通道(16)的感测孔(21); 连接到所述进料通道(16)以将高压空气供应到所述传感孔(21)中的进料部分; 安装在感测孔(21)或进料通道(16)中以测量感测孔(21)或进料通道(16)内的大气压力的大气压力测量部分(30); 以及用于接收大气压力测量部分(30)的信号的控制单元(40)。 感测孔(21)的底端延伸到预定的保持器(20)的磨损高度。 因此,当保持环(20)磨损到预定的有限磨损高度时,感测孔(21)的底端打开。 因此,供给到感测孔21的高压空气向外部排出,感测孔21的内部空气压力降低。 与使用保持环(20)的预设使用时间的现有头不同,由于控制单元(40)接收来自大气压力测量部的信号以确认,可以有效地使用保持环(20)。

    • The present invention relates to a polishing head of a CMP apparatus including a high strength alloy, which prolongs lifetime of a product by preventing crack generation of a ceramic material by improving a structure of a circular perforated plate constituting the polishing head and replacing the material with a high strength special alloy, and at the same time improves production efficiency by maximizing operation rate of an equipment. A polishing head of a CMP apparatus includes a pressure control device (11), an absorption part (12), a circular perforated plate (100) and a retainer ring (13). The perforated plate (100) includes: a circulate plate type body (110); a pair of alignment grooves (111, 111) formed symmetrically to both sides in the upper center of the body (110); a number of holes (112) formed in the body (110); four perforated holes (113) formed at one side of the body (110); a center groove part (114) formed in a rear center of the body (110); a ball (115) having a part be inserted into the center of the center groove part (114); a circular metal plate (116) which is inserted, fixed and installed in the center of the center groove part (114), and has an exposure hole (116a) formed to expose a part of the ball (115); a plurality of balance pins (117) inserted and fixed around the center groove part (114); and an upper and a lower border part (120, 130) for fixing and surrounding a border of the body (110). The metal plate (116) is constituted with a special alloy including zirconium, titanium, nickel and chrome.
