What is claimed is:



1. A load port for semiconductor manufacturing equipment comprising:

a carrier for accommodating a wafer;

a carrier base for transporting said carrier, while accommodating a wafer, towards an opening of said semiconductor manufacturing equipment to close said opening;

On April 1, 2009, SINFONIA TECHNOLOGY CO., LTD. Changed its name from SHINKO ELECTRIC CO., LTD. Digital Photo Printer CHC-S2145 Superior smear correction technology creates excellent crisp prints. The driver 78 can be switched alternatively between the state in which the decelerating gear-equipped motor 73 is able to rotate at a torque with a large output (i.e., high torque), and the state in which the motor 73 is able to rotate at a torque with a small output (i.e., low torque).

a transporting means for transporting said carrier base; and

control means to control said transporting means to transport said carrier base toward said opening using a relatively small force until said carrier reaches a predetermined position at a predetermined distance from said opening and then transport said carrier base towards said opening using a force greater than said small force used to move said carrier base to said predetermined position.



2. A load port according to claim 1, wherein said carrier base transporting means comprises a cylinder to transport said carrier base; a source to provide a driving force pressure for said cylinder; and a pressure regulating means for regulating the pressure provided from said source to said cylinder.

3. A load port according to claim 2, wherein said pressure regulating means regulates the output of said cylinder between a low output to move said carrier base with the smaller force, and a high output to move said carrier base with a larger force. Download

4. A load port according to claim 1, wherein said carrier base transporting means further comprises a motor which functions as a driving source; a rotational screw which rotates with said motor; a transport member which moves along with said carrier base, by means of rotating said rotational screw; and a controller for switching the output of said motor to achieve said small force and larger force.

5. A load port for semiconductor manufacturing equipment comprising:

an opening in said equipment for taking in a wafer;

a cover for freely opening and closing said opening;

a cover moving means for moving said cover; and

control means to control said cover moving means to move said cover toward said opening using a relatively small force until said cover reaches a predetermined position at a predetermined distance from completely closing said opening and then to move said cover to completely close said opening using a large force which is greater than said small force used to move said cover to said predetermined position.



6. A load port according to claim 5, wherein said cover moving means comprises a cylinder to move said cover; a driving means to provide a driving force pressure for said cylinder; and a pressure regulating means for regulating the pressure provided from said driving means to said cylinder.

7. A load port according to claim 6, wherein said pressure regulating means regulates the force output of said cylinder between a low output to move said cover with the smaller force, and a high output to move said cover with the larger force.

8. A load port according to claim 5, wherein said cover moving means further comprises a motor which functions as a driving source; a rotational screw which rotates with said motor; a transport member which moves along with said cover by means of rotating said rotational screw; and a controller for switching the output torque of said motor to achieve said small force and said large force.

9. A load port for semiconductor manufacturing equipment comprising:

a carrier for accommodating a wafer;
