IPC: H01L21/8247
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent defect due to etching residue and over-etching, and improve manufacturing yield, without precisely managing the etching when an erasing gate is formed. SOLUTION: After polysilicon 303 for forming an erasing gate is grown, the polysilicon 303 is left in a region containing the forming region of an erasing gate, by etching back the polysilicon 303.

Title: Growing method for crystal
Inventor: KAWASAKI HIDEJI
IPC: C30B29/48
Filed: 1990-11-16
Abstract: PURPOSE:To reduce inclusion of impurities and generation of anomalous nuclei by conducting both a heat processing at a specific temperature in a gaseous atmosphere of alkyl compounds and a selective nucleation processing before a crystal forming processing, the alkyl compounds consisting of either group VI hydrides or group VI elements combined with at least one hydrogen or more, wherein each hydride or element produces activated hydrogen at a lower temperature as compared with hydrogen molecules. CONSTITUTION:A nucleation layer 1 with a nucleation density larger than that of a non- nucleation layer 2 is superimposed on the non-nucleation layer 2. A substrate having a free surface, in which the non-nucleation layer 2 and the nucleation layer 1 remain arrayed alternately, is formed by removing the nucleation layer 1 from areas other than those used for the growth of a crystal, thus leaving an area that is small enough for the growth of a crystal but larger than the area provided only by a single nucleus. The substrate is then subjected to a heat treatment at a temperature of less than 600 deg.C in a gaseous atmosphere 3 of alkyl compounds, wherein either group VI hydrides or group VI elements are combined with at least one hydrogen or more. Subsequently, a selective nucleation processing is conducted utilizing a difference of nucleation density between the non-nucleation layer 2 and the nucleation layer 1, so that a single crystal 5 is developed in a source gas 4, thereby leading to reduced inclusion of impurities and generation of anomalous nuclei.
