Amkor Announces New Flip Chip Packaging Technology at SEMICON West2008

Amkor Technology, Inc. (Nasdaq: AMKR) today announced the introduction of a new flip chip packaging technology to be featured at SEMICON West2008 July 15 - 17. The breakthrough in high performance flip chip packaging utilizes an advanced molding process technology that is expected to provide a number of design, cost and performance advantages for field programmable gate arrays, CPUs, graphics processors and ASICs that are widely used in embedded processing applications like PCs, servers, switches and personal gaming machines. The new molding process establishes a platform technology, with the first package offering for flip chip (over) molded ball grid array called FCMBGA.

The advanced molding process used in the FCMBGA package underfills the flip chip die with molding compound providing both mechanical and electrical performance advantages. Mechanical advantages include:

• Larger die to package ratios that reduce package footprints providing improved printed wiring board utilization.
• Reduced package warpage for tighter coplanarity control which improves surface mount assembly.
• Improved package mechanical reliability by reducing material stresses.
• Additional mechanical support for heat sink attachment and multi die designs.

Electrical improvements include:

• Improved signal integrity for noise sensitive high speed signals through the placement of surface mounted passive devices (like decoupling capacitors) closer to the die.
• Reduced signal lengths and power distribution for challenging signal and power integrity requirements by enabling use of coreless or thin core substrates.

“Amkor developed this technology as a cost and performance enhancement to our industry leading SuperFC® package family. The molded structure improves coplanarity without requiring a stiffener, yet offers flexibility for lid attach in large package or high power applications,” said Miguel Jimarez, vice president of Advanced Process Development at Amkor.
