Abstract:
A method of grinding semiconductor articles comprising the steps of:(a) dicing a semiconductor wafer having bumps formed on one surface to separate individual pellets;(b) after step (a), putting the individual pellets on a printed-wiring board with their flat, bump-less surfaces up so that each bump abuts on a selected area of the printed-wiring board to form a space between the individual pellets and the printed-wiring board;(c) after step (b), bonding each pellet to the selected area of the printed-wiring board via its bumps;(d) after step (c), filling the space with a resin and curing the resin whereby the pellets are firmly fixed to the printed-wiring board to provide a pellet-and-wiring board combination as a single solid body; and(e) after step (d), holding fixedly the pellet-and-wiring board combination on a chuck table of a grinder to grind the flat, bump-less surfaces of the pellets to a predetermined reduced thickness.
