Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JPS594145
Kind Code:
A
Abstract:
PURPOSE: To enable to readily adjust the circuit properties of an interior from the exterior even after a package is sealed by forming a thin film element such as resistor or the like on the surface of a package cover plate and coupling the element to the circuit in the package.
CONSTITUTION: The value of a resistor 10 is varied by suitably selecting terminals 11 for altering the resistnce value and connecting via a shortcircuit wire 12. Since the bias voltage of an amplifier 3 is varied by the operation, the gain- frequency characteristic of the amplifier 3 can be consequently externally controlled.
