Abstract

PURPOSE:To eliminate the mechanic stress at the sealing part between a cap and a package body, by sealing the gas for leak measurement between the cap of the package and the package body. CONSTITUTION:The metallic cap 3 is unitarily formed to the package body 1, and the element is hermetic-sealed. Further, between the package body 1 and the cap 3, He gas is sealed. This He gas sealing is easily performed by a method wherein many package bodies 1, caps provided with fine holes on the lower side wall, etc. are put in a partially transparent vessel with vacuum inside called a glove box, then the cap is unitarily formed to the package body 1, thereafter He gas is supplied from the fine hole, and next the fine hole is covered with solder, etc. The leak test can be formed, by putting the He gas sealed package in the vacuum vessel, an He leak measuring apparatus, and thus detecting whether the He gas in the vacuum vessel is leaked or not.

By the way, in a package, a seal failure has a great adverse effect on the element, so a leak test of the package is frequently conducted. This test method will be explained below.・Leave the mother package in a pressurized tank filled with He gas for a certain period of time. The conditions for pressurization and standing time at this time are, for example, 2 atm and 3 hours.

Background 1. Problems with the background technology 4. However, since the leak test described above requires the step of placing the package in a pressurized tank, excessive mechanical stress is applied to the package in the case of a large cage. There was a risk that the gun would destroy the seal between the package cap and the T44 package. In addition, in order to suppress mechanical stress, if He gas is supplied into the shoe cage at a low pressure without fear of breaking the seal, it is possible to avoid leaving the shoe cage in the pressurized tank. This increased the time and reduced work efficiency. Moreover, when He gas is supplied to the /4' package in the pressurized tank, the He gas is adsorbed on the outer wall surface of the package due to He pressurization, so when measuring the leakage of H gas in the sanding process. He in the package
Along with the gas, He gas adsorbed on the outer wall surface of the package was also measured, and there was a risk that true measured values could not be obtained.

Summary of the Invention The main feature of the present invention is that a gas for leakage measurement is sealed between the cap of the cap and the package body. With this structure, when performing a leak test on a package, it is possible to perform the conventional process of pressurizing the package in a pressurized tank. It can be placed inside the room to measure leakage gas. Therefore, the mechanical stress at the sealing portion between the cap and the package body can be eliminated, and the working time can be shortened by omitting the pressurization process.

However, since the hermetically sealed package of the present invention has a structure in which HaW gas is sealed between the main package body 1 and the cap 3, the package filled with He gas can be
A leakage test can be performed by placing the device in the vacuum container of a leak measuring device and detecting the presence or absence of leakage of H gas in the vacuum container. As a result, a seal failure between the package body 1 and the cap 3 can be confirmed. Therefore, since there is no He pressurization process between the cap 3 and the package body 1 in the pressurized tank as in the past, the seal between the character f3 and the package body 1 is sealed without applying mechanical stress to the package. There is no fear of destruction at all. In addition, as mentioned above (there is no He pressurization process, and the process of supplying H gas between the package cap and the package body 1 can be carried out in a short time, the work time is reduced compared to the conventional case). can.
