- MCM-C
- Built on cofired ceramic substrate. High layer count. Used in General-purpose workstations, Analog circuits and Mixed A/D circuits.
- MCM-D
- Deposited thin film substrates and thin film conductors. Very high routing density. Used in parallel computers, High-density image processing equipment and Digital high-speed terminals.
- MCM-L
- Laminated multilayer substrates. Utilizes the existing PCB technology. Very cost effective. Used in Personal Computers, Cellular Phones and Commercial Equipment.
- MCM-L/D
- Combines the MCM-L and MCM-D technologies. Thin film layers deposited on the top of multilayer laminate substrate can be used for routing critical signals.
- MCM-C/D
- Combines the MCM-C and MCM-D technologies. Thin film layers deposited on the top of multilayer ceramic substrate can be used for routing critical signals.
