Title:
エピタキシャル成長用サセプタおよびエピタキシャル成長方法
Document Type and Number:
Japanese Patent JP4285240
Kind Code:
B2
Abstract:
A susceptor (10) for use in an epitaxial growth apparatus and method where a plurality of circular through-holes (10b, 10c) are formed in the bottom wall of a pocket (10a) in an outer peripheral region a distance of up to about 1/2 the radius toward the center of Lhe circular bottom wall. The total opening surface area of these through-holes (10a, 10c) is 0.05 to 55% of the surface area of the bottom wall. The opening surface area of each of the through-holes (10b, 10c) provided at this outer peripheral region is 0.2 to 3.2 mm 2 and the density of the through-holes (10b, 10c) is 0.25 to 25 per cm 2 , After a semiconductor wafer is mounted in the pocket (10a), epitaxial growth is carried out while source gas and carrier gas (i.e., reactive gas) is made to flow on the upper surface side of the susceptor (10) and carrier gas is made to flow on the lower surface side.
