Abstract: The present invention discloses an auto-assembling system for assembling the frames and the covers of devices, completely. The auto-assembling system configured on a platform includes a transportation device, a lateral assembling power module, a buffer, a control circuit and a power source. The above-mentioned transportation device has a fillister for receiving the frames and the covers of the devices. The frames that are combined with the covers in the transportation device are driven by the horizontal assembling power module. The buffer is used as a cushion for the lateral assembling power module. When the lateral assembling power module moves to the buffer, it causes the frames and the covers to be assembled. The control circuit connects to the lateral assembling power module for controlling the activating timing of the foregoing lateral assembling power module. The power source connects to the lateral assembling power module and the control circuit to provide the power for them.

Abstract: To reduce the width of a MOSFET gate, the gate is formed with a hardmask formed thereupon. An isotropic etch is then performed to trim the gate in order to reduce the width of the gate. The resulting gate may be formed with a width that is narrower than a minimum width achievable solely through conventional projection lithography techniques.
