The cell phone continues to be one of the primary drivers for the electronics industry, constantly delivering new features such as mega pixel cameras, video recorders, and MP3 playback capability, while at the same time reducing size, power consumption, and cost. Among the key advances in semiconductor and packaging technologies that have made this progress possible is the multi-chip package, or MCP, in which two or more ICs are integrated in the same package.
The Portelligent study of die and package integration trends, led by Jeff Brown, Principal Analyst, has found that cell phones were the first major category of portable electronic products to reach the 90 % MCP milestone, in 2004, while the remainder of the handheld device market nearly reached that threshold in 2005.
The remaining 10 % of devices not utilizing MCP’s are ultra-low cost cell phones and hard disk drive-based handheld GPS devices and portable media players.
In contrast to the rapid increase in the proportion of product designs that exploit MCPs, however, the quantity of MCP’s per device, on average, has remained steady between 2 and 2.5. “The maximum number of MCP’s we are seeing in handheld devices has actually declined from 2003 contributing to the relatively constant average”, noted Brown. “When W-CDMA handsets from Japanese OEM’s were first introduced into Europe in 2003, it was not uncommon to find between 7 and 9 MCP’s in a phone. By the end of 2005, similar handsets had between 3 and 4 MCP’s.“
“This finding regarding the number of MCPs in the average consumer electronic product is somewhat contrarian, but on reflection it makes sense,” commented president and CTO David Carey. “The system designers are adding features to their products every year, but the semiconductor industry is enabling greater functionality through die integration as well as package integration.”
