Abstract

The invention provides a plate structure with heat diffusivity and high electrical conductivity comprising the linear structure of the carbon element and manufacturing method thereof and an electric device using the plate structure. The plate structure has multiple beam linear structure (12), including each other to maintain their space the way the first configuration includes a number of linear carbon structure, and a number of thread-like structures described in beam (12) to each other than the first gap to maintain the second largest allocation of space the way; filler layer (14), filled between the first and the second gap for the structure to maintain a number of linear beams (12).

Description

technical field [0001] The present invention relates to a plate-like structure and a manufacturing method thereof, in particular to a plate-like structure having a linear structure including carbon elements oriented in a direction perpendicular to the plate surface and a manufacturing method thereof, and the use of such a Electronic equipment with a plate-like structure. Background technique [0002] In an electronic component used in a central processing unit (CPU: Central Processing Unit) of a server or a personal computer, it is necessary to efficiently dissipate heat generated by a semiconductor element. Therefore, it has a structure in which a heat spreader made of a material having high thermal conductivity such as copper is provided via a heat conduction plate such as an indium plate provided directly above the semiconductor element. [0003] However, since the price of indium has risen due to a sharp increase in demand for rare metals in recent years, it is desired ...
