Abstract:
A method of forming a multi-tipped probe ring to probe a semiconductor device having a plurality of contact pads arranged in a fixed pattern, comprising the steps of:forming a first masking layer on a top surface of a silicon substrate;etching a first trench having a bottom in the silicon substrate utilizing the first masking layer;forming a second masking layer on the first trench;etching a plurality of second trenches having sidewalls tapering to a point into said bottom of said first trench utilizing said second masking layer;depositing a conductive layer on said second masking layer and said second trenches to form a plurality of integral conductive lines and probe points in a predetermined pattern which are aligned with the contact pads;depositing a first interlevel dielectric on the conductive lines and said second masking layer;forming a portion of a first shield conductor on said first interlevel dielectric;depositing a dielectric layer on said portion of a first shield conductor and said first interlevel dielectric layer;planarizing said dielectric layer; andremoving said silicon substrate.
