Abstract

In the fabrication of semiconductor packages, a leadframe is formed by masking and etching a metal sheet from both sides, and a plastic block (110A) is formed over a plurality of dice attached to die pads (1C, 10, 33B, 34D, 34O, 34R, 34S) in the leadframe. A laser beam (198A, 199A) is used to form individual plastic capsules (127B, 127C) for each package, and a second laser beam (198A; 199A) is used to singulate the packages by severing the metal conductors, tie bars (374, 414) and rails between the packages. A wide variety of different types of packages, from gull-wing footed packages to leadless packages, with either exposed or isolated die pads (1C, 10, 33B, 34D, 34O, 34R, 34S), may be fabricated merely by varying the patterns of the openings in the mask layers and the width of the plastic trenches created by the first laser beam (198A; 199A). The most suitable drawing: Fig. 11C.
