Title:
ANISOTROPIC ELECTROCONDUCTIVE SHEET AND METHOD FOR MANUFACTURING ANISOTROPIC ELECTROCONDUCTIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2023/234089
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an anisotropic electroconductive sheet configured to stably withstand repeated inspection while preventing force from being exerted on an object for inspection, such as a semiconductor device, by establishing a configuration in which through-sections are each divided to have a plurality of through-holes. An anisotropic electroconductive sheet (1) has a sheet-shaped insulating layer (2) made of a resin material, a plurality of through-sections (3) penetrating the insulating layer (2) in the thickness direction, and through-electrodes (31) (or through-electrodes (32)) made of a metal thin film formed in the respective through-sections (3). The through-sections (3) are segmented by partitions (2d) and are formed independently in the circumferential direction. The through-electrodes (31) (or the through-electrodes (32)) are disposed in the through-holes (2c).
