It is frequently necessary to use load or line-terminating resistors in combination with circuits contained in semiconductor chips. If the resistors are placed in the chips, they increase the power dissipation and use valuable space in the chip. In the plan described, the resistors are fabricated within the internal layers of a multilayer ceramic carrier for the chip and connected by means of the appropriate wiring built into the chip carrier. The figure shows section 1 of a typical resistor layer from such a multilayer ceramic chip carrier. Mesh pattern 2 is a common pattern for a ground or voltage reference plane and is located on the underside of section 1, as shown. The blank areas 3 are sometimes used to place "via" connections to other layers.
