United States Patent6531338   
Link to this pagehttp://www.wikipatents.com/6531338.html
Inventor(s)Akram; Salman (Boise, ID); Brooks; Jerry Michael (Caldwell, ID)
AbstractA semiconductor structure includes flip chips or other semiconductor devices that are mounted on printed circuit boards. The printed circuit boards are stacked to increase the circuit density of the semiconductor structure. The printed circuit boards include cavities or openings to accommodate the flip chips or semiconductor devices and thus reduce the overall size of the semiconductor structure. The flip chips or semiconductor devices from adjacent printed circuit boards may extend into the cavities or openings or simply occupy the cavities or openings from the same printed circuit board.

BACKGROUND OF THE INVENTION

The present invention relates in general to an apparatus and method for increasing semiconductor device density, and, more particularly, to arranging semiconductor devices within and over substrates to achieve densely packaged semiconductor structures.

Chip On Board techniques are used to attach semiconductor dice to a printed circuit board, including flip chip attachment, wirebonding, and tape automated bonding (TAB). Flip chip attachment consists of attaching a flip chip to a printed circuit board or other substrate. A flip chip is a semiconducto
