摘要:
A temperature testing device in which a sample-receiving sealable chamber from which a specimen can be easily detached and a cooling portion of a refrigeration unit are inserted into a single vacuum vessel, and in which a gaseous refrigerant is circulated between the cooling portion of the refrigeration unit and the sample-receiving chamber so that the sample-receiving chamber can be cooled.

The present invention provides a substrate treating method including the steps of joining a one-side surface of a substrate to be treated to a support substrate, treating the substrate to be treated in the condition where the substrate to be treated is supported by the support substrate, and removing the support substrate from the substrate to be treated. The step of joining the substrate to be treated to the support substrate includes melting a joint bump formed on the substrate to be treated so as to join the substrate to be treated to the support substrate, and the step of removing the support substrate from the substrate to be treated includes polishing the support substrate so as to remove the support substrate.

The present invention provides a method of manufacturing a multilayer wiring substrate, which can preserve the dimensional stability of a conductor pattern at a fine pitch, solve the restriction on a process from the viewpoint of material selection, and further reduce a manufacturing cost, and a multilayer wiring substrate. A second wiring substrate formed on a supporting sheet made of metal and an adhesive layer are partially stacked on a predetermined region of a first wiring substrate by using the supporting sheet. After the lamination of the second wiring substrate, the supporting sheet is finally etched and removed. The second wiring substrate is stacked only on the portion required to be multilayered on the first wiring substrate to thereby reduce the amount of the construction material of the second wiring substrate.
