Abstract
An improved integrated circuit package of the MLCP type suitable for use both at high operating frequencies and with chips dissipating large amounts of power. Electric power supplying wirings and signal transmitting wirings are disposed on entirely separate surfaces, the power transmitting wirings being formed on entire peripheries of respective, dedicated ceramic plates. Termination resistors for the signal wirings though are formed on the same ceramic plates which contain the power supplying wirings.
