Title: Oxide filling method in shallow trench isolation region
Inventor: JANG SYUN-MING
IPC: H01L21/76
Filed: 1998-03-27
Granted: 1999-09-01
Abstract: The shallow trench isolation region process is emphasized recently as for a semiconductor manufacturing especially the process technique entering the field of quarter-micron or even miniaturized area and used to replace the traditional LOCOS. But, the method of how to fill out the narrower trench according to the miniaturization of design rule has been a great challenge to this technique. Currently, O3-TEOS oxide has been approved to have excellent gap filling property, but when forming the said oxide with the SACVD procedure, the thermal oxide at the bottom and on the sidewall of trench as the lining will reduce the growth rate so as to elongate the processing time and increase the production cost. In order to improve the said problem, the invention provides a kind of improving oxide filling method in shallow trench isolation region which is that before forming the thermal oxide lining, directly to apply SACVD to form O3-TEOS oxide. Because there is no thermal oxide preventing the oxide growth at the bottom and on the sidewall of trench, the trench can be filled out quickly; then, applying thermal annealing treatment in the oxygen environment, meanwhile to make the oxide more densed for increasing anti-corrosion capability and for automatically forming a thermal oxide lining at the bottom and on sidewall of the trench by thermal diffusion effect.

Granted: 2001-06-23
Abstract: In this invention, the method for controlling the acceleration of step motor includes the following procedures. At first, the input pulse frequency of step motor is gradually increased in order to increase the rotating speed of the step motor, in which the pulse voltage is the voltage when the step motor generates the torque that is roughly close to the maximum torque under the rotating speed. Additionally, the increase of the pulse frequency is made to exhibit a gradual variation when the rotating speed of motor closes to the assigned rotating speed. When the rotating speed of the motor reaches the assigned rotating speed, the pulse frequency is fixed at one frequency of the assigned rotating speed. For the corresponding method of controlling the acceleration of the step motor stated above, the matching method for controlling the deceleration can include the following procedures. At first, a gradual variation is used to decrease the pulse frequency in order to reduce the rotating speed of the motor. Then, the input pulse frequency of the step motor is gradually decreased so as to make the rotating speed of the step motor decrease, in which the pulse voltage is the voltage when the step motor generates the torque that is roughly close to the maximum torque under the rotating speed.
