  • Controllable radiation curable photoiniferter prepared adhesives for attachment of microelectronic devices and a method of attaching microelectronic devices therewith
    Patent number: 5356947
    Abstract: The present invention provides controllably curable photoiniferter containing adhesive compositions which are suitable for the mounting of microelectronic devices such as flip chips onto transparent wiring boards, a method of making the adhesive compositions, and a method of using the adhesive compositions in order to bond microelectronic devices to transparent wiring boards by intermittent exposure of the adhesive composition to a radiant energy source. The adhesive compositions can be cured in a stepwise fashion by intermittent controlled exposure to a source of radiation thus providing exactly the amount of cure and hardening desired.
