Title: Manufacture of semiconductor device
Inventor: OONAMI NOBUYUKI
IPC: H01L29/78
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a nitrogen-containing dielectric layer having a low interface state density and a high insulating property by forming a first oxide film having a prescribed thickness between a semiconductor substrate and the dielectric layer by oxidizing the dielectric layer in an atmosphere containing oxygen and hydrogen after the dielectric layer is formed. SOLUTION: A nitrogen-containing first dielectric layer 2 is formed by maintaining the inside of a reactor in a nitrogen suboxide atmosphere for a fixed period of time under a third temperature condition. While the dielectric layer 2 becomes better as the thickness of the layer 2 increases, the maintaining period and temperature of the nitrogen suboxide atmosphere vary depending upon the introducing amount of nitrogen which is required for an applied device. Then a second dielectric layer 3 composed of a silicon oxide film is grown between the substrate 1 and first dielectric layer 2 at the interface between the substrate 1 and layer 2 by maintaining the inside of the reactor in a mixed atmosphere of oxygen and hydrochloric acid under the third temperature condition.  It is desirable to maintain the mixed atmosphere in that of hydrogen and oxygen at the time of growing the second dielectric layer 3.

Filed: 1992-05-11
Abstract: PURPOSE:To make it possible to modify command speed in the way of speed change control by providing speed command values for bringing about an S- curve speed change obtained by approximating current speeds and new set speeds with polylines. CONSTITUTION:A speed commander 1 sets current speeds and new speeds in an acceleration command generator 2 while a CPU 3 calculates the difference between current speed and new speed and one half of the difference is added to a current speed to determine an intermediate point speed in speed change process which is then stored in a RAM 5. Referential command values for varying the speed in S-curve are stored in a PRM 4 and the section between a speed change starting speed and a speed at the intermediate point of the speed change starting speed and speed change ending speed is divided into predetermined number of sections, which are then numbered sequentially starting from the speed change starting speed, and acceleration and duration thereof at each section are also stored. A speed difference detector 6 compares a speed command value with a speed value detected through a speed detector 9 and a drive controller 7 drives and controls a motor 8 based on the comparison results.
