摘要: Passive electronic parts containing a substrate (1) and a passive circuit (2). The substrate (1) has an inorganic insulating layer (11) composed of a mixture of a ceramic component and glass component. The passive circuit (2) is composed of a conductor pattern in general and provided on one surface (111) of the insulating layer (11). It is preferable to polish the surface (111) of the insulating layer (11) on which the circuit (2) is formed. An electronic part can be designed for a smaller pattern area by making the conductive pattern finer.

摘要: A high frequency module capable of effectively dissipating the heat generated by a semiconductor device. The high frequency module comprises a substrate (11), a semiconductor chip (13) fixed on the substrate (11), a top plate (15) placed in contact with the upper surface (13a) of the semiconductor chip (13), and a cap (16) placed in contact with the upper surface of the top plate (15), wherein the cap (16) comprises a flat plate part (16a) and extending parts (16b) extending downward from both ends of the flat plate part (16a). The extending parts (16b) is in contact with the sides of the substrate (11). Thus, the extending parts (16b) are reliably in contact with the sides of the substrate (11) with a wide contact area even if the height of the semiconductor chip (13) involves some variation or the shape of the cap (16) involves some manufacturing variation. Therefore, the heat generated by the semiconductor chip (13) is effectively dissipated to the substrate (11).
