A laser annealing apparatus is disclosed, which is adapted for a laser annealing process. The laser annealing apparatus comprises a laser-generating module, a resistance-measuring module, and a host circuit module, wherein the laser-generating module provides a laser beam to recrystallize an amorphous silicon thin film to form a polysilicon thin film. The resistance-measuring module is adapted for measuring the sheet resistance of the polysilicon thin film. Besides, the host circuit module is electrically coupled to and between the laser-generating module and the resistance-measuring module. The host circuit module outputs a feedback signal to the laser-generating module in accordance with the sheet resistance value. Then, the energy density of the laser beam is optimized. The laser annealing apparatus can improve the quality of the thin film, and increase the yield rate of the laser annealing process.

A container with a handle includes a container body. The container body has a peripheral edge extending outward to form a ring portion. The ring portion is provided with a first slot penetrating through the ring portion. The first slot cuts the ring portion to form a first handle portion and a first edge portion completely connected to the container body. In addition, the ring portion is further provided with a second slot penetrating through the ring portion. The first slot and the second slot are respectively located on two opposite sides of the ring portion. The second slot cuts the ring portion to form a second handle portion and a second edge portion completely connected to the container body. The first handle portion and the second handle portion each have two ends connected to the container body and may be pulled up as the handle.
