Abstract
An integrated circuit package comprises a plurality of thin flat epoxy-glass layers which are arranged in a stack and are laminated together by prepreg layers that lie between the epoxy-glass layers. This stack has a cavity which is staircase-shaped and extends from an outer epoxy-glass layer to an internal epoxy-glass layer, goes parallel along the internal epoxy-glass layer and then penetrates through it. Patterned electrical conductors lie on the flat surface of the internal epoxy-glass layer, including wire bonding pads on its exposed flat surface portion.
