By 2010, the "More Than Moore's Law" movement—which focuses on system integration rather than transistor density—will lead to revolutionary megafunction electronics Moore's Law Integrated Circuits deal with only 10 percent of the system. The other 90 percent is still there, showing up as an array of bulky discrete passive components—such as resistors, capacitors, inductors, antennas, filters, and switches—interconnected over a printed-circuit board or two. System-on-package (SOP) approach combines ICs with micrometer-scale thin-film versions of discrete components, and it embeds everything in a new type of package so small that eventually handhelds will become anything from multi- to megafunction devices. SOP products will be developed not just for wireless communications, computing, and entertainment. Outfitted with sensors, SOPs could be used to detect all manner of substances, toxic and benign, including chemicals in the environment, in food, and in the human body.
