Embodiment 1

[0047] The wafer transfer system includes: a box opening mechanism for an 8-inch wafer sealed box, a box-opening mechanism for a 12-inch wafer sealed box, a manipulator with an imaging unit; a control unit for controlling the manipulator and the box-opening mechanism.

[0048] According to the specific application environment, it is also necessary to be able to maintain a cleanliness level 1 microenvironment and the corresponding operation interface (display).

[0049] The specific transmission method is as follows:

[0050] 1) The operator places the sealing box containing the 8-inch wafer on the opening mechanism SMIF corresponding to the 8-inch wafer sealing box, and places the empty-load compatible sealing box on the Loadport of the 12-inch wafer opening mechanism;

[0051] 2) The two box opening mechanisms automatically open the SMIF Pod and Adapter FOUP respectively, and the scanning sensor on the robotic arm scans to confirm the number and position of wafers;

Abstract

The invention provides a wafer transport system and a transport method and belongs to the field of microelectronic technologies. The invention aims to solve the problem of failure to transmit wafers during the machining of wafers of different sizes by a wafer matching device of a specific size in the prior art. The transport system includes a first box opening mechanism for opening and closing a first wafer sealing box, a second box opening mechanism for opening and closing a second wafer sealing box, a mechanical arm for transferring wafers from the first wafer sealing box to the second firstwafer sealing box, and a control unit which is used for controlling the mechanical arm and the box opening mechanisms. With the wafer transport system and the transport method of the invention adopted, wafers of different sizes can be transferred between different sealing boxes; wafers of the same size can be also transferred between the same sealing boxes. The wafer transport system and the transport method can be suitable for the batched operation or batch-integrated operation of wafers of the same size, or the machining of wafers of different sizes on the wafer processing device of the specific size.

Description

technical field [0001] The invention belongs to the technical field of microelectronics, and in particular relates to a wafer transmission system and a transmission method. Background technique [0002] The integrated circuit industry uses a special sealed box that can isolate pollution to hold wafers (Wafer), and its specifications need to strictly follow the global unity. The International Organization for Semiconductor Equipment and Materials (SEMI) stipulates that the sealed box used for holding 12-inch wafers is FOUP (Front Opening Unified Pod, front-opening standard box), and the container for holding 8-inch wafers is provided by the entire factory. The initial design determines whether it is an open type or a sealed type. When using a sealed container, the box-opening mechanism SMIF (Standard Mechanical Interface) matching the production equipment is required. The corresponding sealed box for holding an 8-inch wafer is called SMIF Pod. Generally speaking, FOUP and SM...
