    摘要: A die-attach film and a method of manufacturing the same, the method including providing a dicing film layer with the attach layer thereon, the dicing film layer being prepared from a photocurable adhesive composition and including an attach layer region overlapping the attach layer such that the attach layer blocks inflow of oxygen into the attach layer region, and a ring frame region, the ring frame region having an upper surface that is adjacent to the attach layer and is exposed to air or an oxygen atmosphere such that oxygen flows into the ring frame region; and irradiating UV light to a back side of the dicing film layer to induce photocuring of the attach layer region, the oxygen in the ring frame region acting as a radical scavenger and suppressing photocuring of the ring frame region.
