STATS ChipPAC Delivers Low Cost Flip Chip Technology

SINGAPORE -- 05/19/09, UNITED STATES -- (MARKET WIRE) -- May 18, 2009 -- STATS ChipPAC Ltd. ("STATS ChipPAC" or the "Company") (SGX-ST: STATSChP) today announced a new flip chip technology that offers a significant cost savings over standard flip chip packages with price points well below wire bond packages. STATS ChipPAC's low cost flip chip technology features an innovative routing efficient interconnection structure and a simplified substrate technology design coupled with improvements in assembly technology such as a cost effective mold underfill process.

Although the industry is experiencing a shift from wire bonding to flip chip interconnect due to the increase in gold bonding wire costs, STATS ChipPAC has taken an aggressive approach to driving down the cost of flip chip technology. Until now, the high price of substrates and the elaborate and costly underfill step in flip chip technology have been barriers to flip chip adoption in mid- to low-pincount packages of 100 to 700 pins. For semiconductor companies interested in converting their package designs from a wire bond interconnect to flip chip interconnect, the typical industry cost premium has been in the 30% range.

STATS ChipPAC has achieved an unprecedented cost reduction with its low cost flip chip technology, essentially offering semiconductor companies the opportunity to have flip chip technology at price points below wire bond packaging. Rather than focusing on incremental changes in individual materials or processes, STATS ChipPAC took a comprehensive approach to reengineering the package structure and key processes to design the cost out of each element of flip chip technology, from substrate design to bump and the assembly process.

"The goal with our low cost flip chip program was to not merely identify ways to reduce the cost of our packages incrementally, but to have a clear breakthrough in fundamentally improving the cost of the flip chip packaging process," said Dr. Raj Pendse, Vice President, Technical Marketing, STATS ChipPAC. "Where a conversion to flip chip technology may have been cost prohibitive in the past, we are able to offer customers an advanced flip chip interconnect solution with a cost effective price point compared to wire bond packaging."

Since traditional substrate costs average 50% or more of the total package cost, STATS ChipPAC designed a new routing efficient interconnection scheme that reduces the substrate layer count and complexity. The company's new 2-layer laminate substrate design has a significantly lower cost than traditional 1-2-1 build-up substrates used for flip chip interconnection. The new substrate achieves equal or higher routing density with the same laminate substrate design rules as wire bond substrates.

The standard underfill process for flip chip interconnect is typically the slowest and single most expensive process step in the flip chip assembly process. In conjunction with the new interconnection and substrate design, STATS ChipPAC utilizes an efficient mold underfill technology which provides higher process throughput at a lower cost than conventional capillary underfill. Furthermore, in anticipation of the industry's shift to lead-free bump and halogen-free bill of materials, the low cost flip chip technology developed by STATS ChipPAC features a true lead-free bump composition which has proven to be effective with the mold underfill process.

Dr. Pendse continued, "We qualified the first phase of our low cost flip chip program in 2008 and today are in high volume production with packages such as Fine Pitch Ball Grid Array (FBGA) for mobile applications. As we move into the second phase of our program, through further innovation we are significantly increasing the routing density of our solution without stretching the substrate design rules. As a result, we believe we will be able to offer customers low cost flip technology for more than 75% of real die designs."
