Abstract

(목적)(purpose)

본 발명은 대경의 웨이퍼에 확실하게 테이프를 접착시킬 수 있는 웨이퍼 마운터의 웨이퍼 지지방법, 그 장치 및 그 장치를 구비한 웨이퍼 마운터를 제공함을 목적으로 한다.An object of the present invention is to provide a wafer support method of a wafer mounter capable of reliably attaching a tape to a large diameter wafer, an apparatus thereof, and a wafer mounter provided with the apparatus.

(구성)(Configuration)

본 발명은 테이블판(20)과 웨이퍼(W)사이에 형성되는 압력공간(34)을 압력설정벽(29)으로 1차 압력공간(34a)과 2차 압력공간(34b)으로 구획하고, 상기 압력조정벽(29)과 웨이퍼(W)사이에 형성되는 조리개통로(35)의 조리게 작용에 의해 상기 1차 압력설정공간(34a)에 웨이퍼(W) 중앙부에 작용하는 소요의 백업 압력을 설정하고, 상기 2차 압력공간(34b)을 대기중에 연통시켜서 웨이퍼(W) 전체에 작용하는 백업압력은 웨이퍼(W)고정용 진공흡착력보다 작게하는 구성으로 한다.The present invention divides the pressure space 34 formed between the table plate 20 and the wafer W into a pressure setting wall 29 into a primary pressure space 34a and a secondary pressure space 34b. By the action of the diaphragm of the aperture passage 35 formed between the pressure adjusting wall 29 and the wafer W, the required backup pressure acting on the central portion of the wafer W is set in the primary pressure setting space 34a. The backup pressure acting on the entire wafer W by communicating the secondary pressure space 34b in the air is smaller than the vacuum suction force for fixing the wafer W.
