<p>PURPOSE:To reduce the pellet rising phenomenon during the incorporating period of an electronic element and improve the yield by slanting in parallel two faced cut surfaces so as to form a parallelogram, and providing slants toward an electrode surface on the two cut surfaces so that the two cut surfaces become at least a trapezoid or reversed trapezoid. CONSTITUTION:All (e2, f2, g2, and h2) of four cut surfaces of a chip are cut in parallel to have the same slant angle theta, and all of the four cut surfaces are made into a parallelogram. Since the slants are provided on the cut surfaces, in the case where the cut surfaces drop in a sealed glass material in an up-and- down state of the cut surfaces, a reverse moment proportional to the side length and slant angle actuates thereto, and thus, an electronic element is reversed at 90 deg., and stands in an up-and-down state of the electrode surfaces. Whereby the pellet rising phenomenon is reduced, and the yield can be improved.</p> |
