Title:
SEMICONDUCTOR ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/125520
Kind Code:
A1
Abstract:
A semiconductor element which comprises: a ceramic element that contains sintered ceramic particles; and a first external electrode and a second external electrode that are respectively arranged on the end faces of the ceramic element. The sintered ceramic particles are composed of a perovskite compound that contains at least Ba and Ti, and have an average particle diameter of 0.4-1.0 μm. When a region in a cross-section of the semiconductor element is selected and observed with a scanning electron microscope, the contact ratio of the sintered ceramic particles as calculated on the basis of the total of the peripheral lengths of the sintered ceramic particles present within the region, the total of the peripheral lengths of the pores present within the region, the outer peripheral length of the region and the contact lengths of the sintered ceramic particles present within the region is 45% or more.
