Title: Manufacture of semiconductor device
Inventor: HIEDA KATSUHIKO
IPC: H01L27/04
Filed: 1985-03-28
Abstract: PURPOSE:To obtain a capacitor electrode, whose sheet resistance is low and uniform, by using a forming method, by which impurities can be readily doped even at a deep part of a polycrystalline silicon film, which is located at the bottom part of a groove, when an MOS capacitor having a groove structure is formed. CONSTITUTION:At first, a first polycrystalline silicon film 13, in which impurities are not doped, is deposited. Then, a second polycrystalline silicon film 14, in which impurities are doped, is deposited. At this time, it is desirable that the width of the silicon film 13 is smaller than 1/2 the width H of a groove 16. A gap is provided at the central part of the groove 16. The second polycrystalline silicon 14 is embedded in the gap S. Heat treatment is performed so as to diffuse the impurities in the silicon film 14 into the silicon film 13. Thereafter, flattening of the surface is performed by a fluid material film 15. The silicon films 13 and 14, whose surfaces are flattened, are obtained by performing the etching on the entire surface under the conditions the etching speeds for the fluid material film 15 and the silicon film 14 become equal with each other. Patterning is performed, and the capacitor electrode is formed.
