Title: Probing apparatus with temperature-adjusting mechanism

Description:
TECHNICAL FIELD 
     The present disclosure relates to a probing apparatus for semiconductor devices, and more particularly, to a probing apparatus for semiconductor devices using pressurized fluid to control the testing conditions. 
     DISCUSSION OF THE BACKGROUND 
     Generally, it is necessary to test the electrical characteristics of integrated circuit devices at the wafer level to check whether the integrated circuit device satisfies the product specification. Integrated circuit devices with electrical characteristics satisfying the specification are selected for the subsequent packaging process, and the other devices are discarded to avoid additional packaging cost. Test time and cost are much increased with the increasing test requirements and conditions especially increasing temperature ranges. Therefore, a testing device that enables the optimal adjustment of the testing temperature of the integrated circuit device under test remains urgently needed. 
     This Discussion of the Background section is provided for background information only. The statements in this Discussion of the Background are not an admission that the subject matter disclosed in this section constitutes prior art to the present disclosure, and no part of this Discussion of the Background section may be used as an admission that any part of this application, including this Discussion of the Background section, constitutes prior art to the present disclosure.

It shall be understood that no limitation of the scope of the disclosure is hereby intended. Any alteration or modification of the described embodiments, and any further applications of principles described in this document, are to be considered as normally occurring to one of ordinary skill in the art to which the disclosure relates. Reference numerals may be repeated throughout the embodiments, but this does not necessarily mean that feature(s) of one embodiment apply to another embodiment, even if they share the same reference numeral. 
     It shall be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections are not limited by these terms. Rather, these terms are merely used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present inventive concept. 
     The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limited to the present inventive concept. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It shall be further understood that the terms “comprises” and “comprising,” when used in this specification, point out the presence of stated features, integers, steps, operations, elements, or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof. 
     The present disclosure is directed to a probing apparatus comprising temperature control mechanisms with flow lines. In order to make the present disclosure completely comprehensible, detailed steps and structures are provided in the following description.
