    摘要: A method for packaging a semiconductor is provided to allow uniform coating of a die attachment paste, shorten a B-staging time, and improve die pick-up characteristics and die attachment characteristics. This method includes preparing a die attachment paste with a viscosity of 1,500 to 100,000 cps; rotating a wafer and applying the die attachment paste to an upper surface of the wafer into a predetermined thickness; and B-staging the paste applied on the wafer. This method makes it possible to reduce costs by substituting for WBL (Wafer Backside Lamination) film, uniformly apply a die attachment paste to a wafer, freely control a thickness of applied die attachment paste by adjusting viscosity and dosage of discharged paste and a speed of a spin coater, and also shorten a process time by decreasing a B-staging time.

    摘要: Disclosed are a die-attaching paste composition and a method for hardening the same. The present invention provides the die-attaching paste composition applied at a thickness of 200 μm or less on a printed circuit board (PCB), including liquid or solid epoxy, acrylate, a flexing agent, an organic filler and a UV-initiator. The method for hardening a die-attaching paste of the present invention includes carrying out a B-staging process by irradiating a UV-ray to the die-attaching paste composition. According to the present invention, a processing time may be more shortened and storage of the die-attaching paste may be more significantly improved when a B-staging process using UV rays is applied than when a conventional thermal crosslinking method is used, and therefore a manufacturing cost in the conventional assembly industries may be decreased. Also, the B-staging process may be uniformly carried out and physical properties of the die-attaching paste may be adjusted to desired characteristics since the UV exposure to the die-attaching paste is easily controlled.
