High-frequency circuit

Номер: GB0002123209A
Принадлежит:

In a high-frequency circuit arrangement, passive parts of the circuit are realized in a semiconductor body in which active circuit elements of another semiconductor material are located in recesses in the semiconductor body. When the semi-conductor body is at least in part low-ohmic, a reference plane, for example, the ground plane, can extend very close to the elements of the circuit arrangement. Consequently, due to the shorter connections required, parasitic effects are considerably reduced. When only one active element is mounted and only connections for this element are formed on the semiconductor body, a very suitable support for mounting and measurement is obtained.

PROBLEM TO BE SOLVED: To solve the problem that, in a conventional manner, it becomes more difficult to measure thickness in ball press fitting by observing an image of a relatively flat portion at the peripheral part of a ball, because the relatively flat portion at the peripheral part of the ball having been press-fitted is narrower, due to miniaturization of ball through it is important to accurately measure the thickness in ball press fitting for setting a bonding strength to a desired value, in hole bonding.

PROBLEM TO BE SOLVED: To prevent a fine recessed part from being formed owing to the sticking of a cut fragments by increasing the width of the groove of an wedge from both end parts to the intermediate part and decreasing the depth of the groove from both end parts to the intermediate part. SOLUTION: The wedge 8 is so formed that the width of the plane shape of the groove 9 formed in the reverse surface of a long leg piece 8a is increased from both ends 9a and 9b to the intermediate part 9c and the depth of the groove 9 viewed from the side section is decreased from both end parts 9a and 9b to the intermediate part 9c.

A semiconductor device package that incorporates a combination of ceramic, organic, and metallic materials that are coupled using silver is provided. The silver is applied in the form of fine particles under pressure and a low temperature. After application, the silver forms a solid that has a typical melting point of silver, and therefore the finished package can withstand temperatures significantly higher than the manufacturing temperature. Further, since the silver is an interfacial material between the various combined materials, the effect of differing material properties between ceramic, organic, and metallic components, such as coefficient of thermal expansion, is reduced due to low temperature of bonding and the ductility of the silver.
