Electrical component e.g. surface acoustic wave filter, for use in portable apparatus, has intermediate film for overstretching lower chip, and upper chip arranged on film above lower chip, where chips are provided with electrical terminals

摘要

The component (EB) has a lower housing portion (UG) with a concave portion (KA), and a lower chip (UC) and an upper chip (OC) with electrical terminals (EA1, EA2), where the lower chip is arranged in the concave portion. The terminals are internally interconnected to the lower chip and the upper chip. An intermediate film (ZF) partially overstretches the lower chip, and the upper chip is arranged on the film above the lower chip. The housing portion is made of ceramic e.g. high temperature co fired ceramic (HTCC) and low temperature co fired ceramic (LTCC), and polymer. An independent claim is also included for a method for manufacturing an electrical component.
