An integrated circuit (IC) structure includes a substrate, an interconnect structure, metal lines, a liner, a protecting layer, and a nitride-free passivation layer. The interconnect structure is over the substrate. The metal lines are over the interconnect structure. The liner is conformally formed on the metal lines. The protecting layer is over the liner. The nitride-free passivation layer continuously extends from the liner to the protecting layer and forms an interface with the liner.

Passivation layer for integrated circuit structure and forming the same

An integrated circuit (IC) structure includes a substrate, a transistor, an interconnect structure, a plurality of metal lines, an oxide liner, a passivation layer, and a nitride layer. The transistor is on the substrate. The interconnect structure is over the transistor. The metal lines is on the interconnect structure. The oxide liner is over the plurality of metal lines. The passivation layer is over the oxide liner and is more porous than the passivation layer. The nitride layer is over the passivation layer.

A method includes forming metal lines over an interconnect structure that is formed above transistors; depositing a liner layer over the metal lines using a first high density plasma chemical vapor deposition (HDPCVD) process with a zero RF bias power depositing a first passivation layer over the liner layer using a second HDPCVD process with a non-zero RF bias power; and depositing a second passivation layer in contact with a top surface of the first passivation layer using a third HDPCVD process with a non-zero RF bias power.

An encoder signal compensation method and the apparatus thereof are described. The encoder signal compensation method includes the following steps. First, encoder output signals are read to calculate compensation parameters. Subsequent encoder output signals are compensated according to the calculated compensation parameters and the compensated encoder output signals are utilized to control a printing process. The encoder signal compensation method is effective in eliminating width errors and phase errors of the encoder output signals. Another embodiment of the invention is to provide a printing apparatus utilizing the encoder signal compensation method to reduce high frequency banding, effectively improving the printing quality.
