MCM

(MultiChip Module or MicroChip Module) A chip package that contains several bare chips mounted close together on a substrate (base) of some kind. The short tracks between the chips increase performance and eliminate much of the noise that external tracks between individual chip packages can pick up. MCM also allows CMOS and bipolar technologies to be used in the same package.

MCMs are classified by substrate: an MCM-C uses a ceramic substrate with wire bonding between the chips. MCM-D uses a dielectric layer over a ceramic, glass or metal substrate, and thin film interconnects are created on the dielectric layer. MCM-S uses a silicon substrate with tracks created in the silicon like regular ICs. Transistors can also be formed in the substrate. MCM-L uses a laminated circuit board with up to 25 tracking layers. MCM-L evolved into the multichip module (see MCP).

MCMs followed "hybrid microcircuits," which used a ceramic base, but MCMs typically have higher component and tracking densities. See system in package, chip package and Trilogy.

Abbr. for “thousand circular mills.” See wire size.

Intel had originally developed the EMIB as an alternative to what's known as a silicon interposer, the "floor" or "foundation" of a multichip module. The problem with an interposer is that, like a floor, it needs to cover the entire space underneath the module, making it expensive to manufacture.
