Title:
【発明の名称】半導体チップ検査用プローブの製法
Document Type and Number:
Japanese Patent JP3374890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the size of an inspection probe and to eliminate crosstalk and mismatching of characteristic impedance, by forming a contact section that connects a contact point pad of a semiconductor chip and a test circuit provided next stage out of conductive springs each having a projection shape which are electrically insulated. SOLUTION: A plurality of contact sections 2 are provided to positions on a substrate 1 matched with a contact point pad P of a semiconductor chip O to be inspected. The contact sections 2 are formed of conductive springs each having a projection shape which are electrically insulated with each other and serve to conduct the semiconductor chip O to a test circuit in a rear stage. An object of the probe for inspecting the semiconductor chip is a part except the semiconductor chip O to be inspected and the electrode pad P. The semiconductor chip O can be inspected at the inspecting time when the electrode pad P and contact section 2 in the plate spring structure of the probe for inspecting the semiconductor chip are electrically brought into contact with each other. As a result, flexibility of the contact section 2 in the vertical direction can be achieved so that the contacting can be achieved by virtue of the elastic force even when a step S is existing.
