Abstract: The present disclosure provides a method for forming an integrated circuit (IC) structure. The method includes providing a metal gate (MG), an etch stop layer (ESL) formed on the MG, and a dielectric layer formed on the ESL. The method further includes etching the ESL and the dielectric layer to form a trench. A surface of the MG exposed in the trench is oxidized to form a first oxide layer on the MG. The method further includes removing the first oxide layer using a H3PO4 solution.

Abstract: A moving apparatus for a printer includes a support board, a motor mounted on the support board, an endless belt, and a printing module. A sliding pole is located on the support board. A follower wheel is rotatably mounted on the support board. The motor includes a drive wheel. A belt is set on the drive wheel and the follower wheel. A sliding groove is defined in the printing module. The printing module is located on the support board with the sliding pole located in the sliding groove. The printing module is attached to the belt. The motor is adapted to drive the drive wheel to rotate, and the belt is adapted to bring the printing module to slide on the sliding pole.
