Abstract:
Provided herein are mixed resin systems and the use thereof for wafer-level underfill (WAUF) for three-dimensional TSV packages. In one aspect, there are provided compositions comprising (1) an epoxy resin, (2) a maleimide, nadimide or itaconamide, (3) a toughening agent and (4) a filler. In certain aspects, the invention relates to underfill films prepared from invention compositions. In certain aspects, the invention relates to articles comprising the underfill films described herein.

Claim (Index 1):
A composition comprising:\n (i) a maleimide, nadimide or itaconimide; (ii) an epoxy resin; (iii) a toughening agent; and (iv) a filler; provided, however, that said composition contains substantially no acrylate resin; wherein:\n said maleimide, nadimide or itaconimide is monomeric or oligomeric and can undergo radical cure to form a polymeric network; \n said epoxy resin is a thermosetting resin which can cure into a three-dimensional polymer network; \n said toughening agent reduces the material brittleness of said composition, and increases the impact resistance thereof; and \n said filler modulates the coefficient of thermal expansion (CTE) of the resulting composition; and \n wherein said composition, when cured, has a:\n differential scanning calorimetry (DSC) onset of 100\u00b0 C.-205\u00b0 C.; \n Melt viscosity in the range of 200 Poise-40,000 Poise, and \n gelling temperature of 130\u00b0 C.-180\u00b0 C., as measured by Ares Rheometer at 10 Rad frequency with a 10\u00b0 C./min ramp rate using a sample 1 inch in diameter and 1 mm thick.
