る。(Prior Art) Conventionally, a package for accommodating a semiconductor element, particularly a package for accommodating a glass-encapsulated semiconductor element sealed by welding glass, includes an insulating base and a lid, and accommodates the semiconductor element inside. And an external lead terminal for electrically connecting a semiconductor element housed in the container to an external electric circuit,
A glass member for sealing is applied in advance on the opposing main surfaces of the insulating base and the lid, and external lead terminals are fixed on the main surface of the insulating base, and each electrode of the semiconductor element and the external lead terminal are wired. After the bond connection, the semiconductor element is hermetically sealed inside by fusing and integrating a sealing glass member attached to each of the insulating base and the lid.

Therefore, when a current flows through the external lead terminal made of Kovar or 42Alloy, a large self-inductance is generated in the external lead terminal in proportion to the magnetic permeability, which induces a back electromotive force to become noise, and the noise becomes a semiconductor. The conductivity of Kovar or 42Alloy is 3.0 to 3.5% (IAC
S) and low. Therefore, when a signal is propagated to an external lead terminal made of Kovar or 42Alloy, the signal propagation speed becomes extremely slow, and semiconductor devices that perform high-speed driving cannot be accommodated. The number of electrodes of a semiconductor element has increased significantly with the progress of higher density and higher integration of semiconductor elements housed inside the semiconductor device, and wires of external lead terminals for connecting each electrode of the semiconductor element to an external electric circuit. The width has also become extremely narrow. For this reason, the external lead terminal has become extremely large in electrical resistance in tandem with the low conductivity of Kovar and 42 Alloy described above, and when a signal is propagated to the external lead terminal, the external lead terminal becomes The signal is greatly attenuated due to the electric resistance, and the signal cannot be accurately input to the semiconductor element housed therein, thereby causing a malfunction in the semiconductor element.

能となる。The glass member for sealing 6 has a coefficient of thermal expansion of 85 to
Since the thermal expansion coefficient is 95 × 10 −7 / ° C. and approximates the thermal expansion coefficients of the insulating base 1 and the lid 2, the sealing glass member 6 attached to each of the insulating base 1 and the lid 2 is used. When the semiconductor element 4 in the insulating container 3 is air-tightly sealed by heat melting and integrating, the difference in the thermal expansion coefficient between the insulating base 1 and the lid 2 and the sealing glass member 6 is caused. Is hardly generated due to the heat, the insulating base 1 and the lid 2

Wt％の範囲に限定される。The sealing glass member 6 is made of silica (SiO 2 ) of 55.0.
If it is less than Wt%, the crystallization of the glass proceeds and it becomes difficult to hermetically seal the insulating container 3, and if it exceeds 75.0Wt%, the thermal expansion of the glass becomes small, and the thermal expansion of the insulating base 1 and the lid 2 is reduced. match not made that silica (SiO 2) is 60.0 to 70.0

酸化物は10.0乃至20.0Wt％の範囲に限定される。If the content of sodium and potassium oxides is less than 10.0 Wt%, the melting temperature of the glass at the time of manufacturing the glass is greatly increased, and the workability is significantly deteriorated. If it exceeds 20.0 Wt%, the chemical resistance of the glass is reduced. Since the reliability of the hermetic sealing of the insulating container 3 is greatly reduced due to deterioration, the oxides of sodium and potassium are limited to the range of 10.0 to 20.0 Wt%.

に正常に作動させることができる。The external lead terminal 5 has a magnetic permeability of 200 (CGS) or less, and since the magnetic permeability is low, a large self-inductance is generated in the external lead terminal 5 even when a current flows through the external lead terminal 5. As a result, the noise caused by the back electromotive force induced by the self-inductance can be minimized, and the semiconductor element 4 housed therein can always operate normally.

きる。The external lead terminal 5 has a conductivity of 50% (IAC
S) This is the above, and since it is easy to conduct electricity, the signal propagation speed of the external lead terminal 5 can be made extremely high. Even if the semiconductor element 4 housed in the insulating container 3 is driven at high speed, the semiconductor element 4 Signals can be always sent and received between the power supply and the external electric circuit in a stable and reliable manner.

固に固定することも可能となる。Further, the external lead terminal 5 has a thermal expansion coefficient of 70.
Since the thermal expansion coefficient is approximately 85 × 10 −7 / ° C. and is close to the thermal expansion coefficient of the glass member 6 for sealing,
When using the sealing glass member 6 between the external lead terminal 5 and the sealing glass member 6, a thermal stress is generated between the external lead terminal 5 and the sealing glass member 6 due to a difference in thermal expansion coefficient between the two. It is also possible to firmly fix the external lead terminals 5 with the glass member 6 for sealing.

5.0 to 75.0 Wt%, at least one of sodium and potassium oxides 10.0 to 20.0 Wt%, lead oxide 20.0 to 40.0 Wt
%, A large self-inductance is not generated in the external lead terminal even when a current is applied to the external lead terminal. As a result, the self-inductance causes a back electromotive force. The noise generated is minimized, and the semiconductor element housed therein can always be operated normally.

が可能となる。Also, the signal propagation speed of the external lead terminal can be made extremely high, and even if the semiconductor element housed in the insulating container is driven at a high speed, the transfer of signals between the semiconductor element and the external electric circuit is stable, and It is possible to make sure.

Due to differences in the coefficient of thermal expansion between the insulating substrate and the lid and the sealing glass member, and between the external lead terminals and the sealing glass member even if they are attached and bonded with the sealing glass member. No thermal stress is generated, and it is possible to firmly attach and join all of them.
