Title: Method of manufacturing semiconductor device
Inventor: HARA NOBUO
IPC: H01L29/737
Filed: 2002-05-17
Abstract: <P>PROBLEM TO BE SOLVED: To make uniform a thickness of a film formed by epitaxial growth.  <P>SOLUTION: In the method of manufacturing the semiconductor device, in which a film is formed by epitaxial growth on a semiconductor substrate having a principle plane slightly tilted from a main crystal plane, the film is formed with a growth pressure of 11±1 Torr. Instead of increasing the number of supplied atoms, atoms are caused to move with ease, so that a probability is increased that the atoms are migrated without being trapped by a step on an offset surface and the isotropy of the migration is increased. Thus, the film is formed with a reduced growth pressure. The atoms are less affected by the other atoms by reducing the pressure, thereby increasing an average free travel. Since the migration becomes isotropic, it is possible to make the film thickness uniform.  <P>COPYRIGHT: (C)2004,JPO

The PVT curve crystallizing transition region is formed by connecting the specific volume at the melting point of the resin and the specific volume of the normal temperature at the time of gradual cooling by a straight line. The PVT curves of a melting region and a solidifying region are formed in the same way as a condition at the time of gradual cooling of the resin. The reducing quantities of the specific volumes are calculated from the formed PVT curves to calculate a strain ratio a and an initial setting parameter in warp deformation analysis is formed. By performing the simulation related to injection molding using those, an accurate analyzing result can be obtained.  <P>COPYRIGHT: (C)2004,JPO
