A method of fabricating a stacked structure for forming a damascene process is described. A doped dielectric layer is formed on a substrate. A surface treatment is performed to the dielectric layer to make the dopant concentration in an upper surface layer of the dielectric layer lower than that in the other portions of the dielectric layer. A metal hard mask is then formed on the dielectric layer. Since the dopant conc. in the upper surface layer of the dielectric layer is lowered, the reaction between the metal hard mask and the dopant in the dielectric layer can be inhibited.

A method of reducing the number of particles on a low-k material layer is described. The low-k material layer is formed by a plasma enhanced chemical vapor deposition process, wherein a reaction gas, a cleaning gas, a high-frequency power and a low-frequency power are used. The method comprises turning off the reaction gas and the low-frequency power after the low-k material layer is formed, and continuing to provide the cleaning gas during a delay time.

The present invention provides a method for forming low dielectric constant inter-metal dielectric layer. The method includes providing a semiconductor substrate and forming a first dielectric layer on the semiconductor substrate. Conductor structures are formed in the first dielectric layer. The partial first dielectric layer is removed by using the conductor structures as etching mask. A second dielectric layer is formed between the conductor structures, which has a dielectric constant smaller than the first dielectric layer. The second dielectric layer also alternatively has air voids contained therein to reduce dielectric constant.

A method is used to form an intermetal dielectric layer. According to the invention, an unbiased-unclamped fluorinated silicate glass layer used as a protection layer is formed by high density plasma chemical vapor deposition on a biased-clamped fluorinated silicate glass layer formed by high density plasma chemical vapor deposition to prevent the biased-clamped fluorinated silicate glass layer from being exposed in a planarization process.

A method for fabricating dual damascene is to form an undoped silicate glass (USG) liner before forming a fluorinated silicate glass (FSG) layer which serves as an inter-metal dielectric (IMD) layer on a semiconductor substrate. As a result, the surface sensitivity is eliminated, while a FSG layer with a more uniform thickness and a higher reliability is obtained. In addition, the USG liner increases the adhesion between the FSG layer and other material layers, while no particles are easily formed thereon.

The present invention relates to a method for preventing an electrostatic chuck positioned at the bottom of a plasma vacuum chamber from being corroded during a cleaning process. The electrostatic chuck comprises a conductive substrate functioned as a lower electrode in a plasma process, and an insulating layer on the conductive substrate to electrically isolate the semiconductor wafer and the conductive substrate. The cleaning process involves a plasma process in which a fluorine-contained gas is injected into the plasma vacuum chamber to remove the chemical layer on the inner wall of the plasma vacuum chamber. A ceramic shutter made of SiC material is reposed on the electrostatic chuck and a high DC voltage is applied to the conductive substrate and the ceramic shutter which causes the ceramic shutter and the electrostatic chuck tightly stick together due to an electrostatic reaction. By doing so, the fluorine-contained gas cannot corrode the insulating layer under the ceramic shutter through the gap between the ceramic shutter and the electrostatic chuck.

A method for enhancing adhesion ability between copper and silicon nitride is disclosed. The present method comprises following steps: first, provide a substrate and then form a copper layer on the substrate; second, form a copper phosphide layer on the copper layer; and finally, form a silicon nitride layer on the copper phosphide layer. Herein, the copper phosphide layer is formed by a plasma enhanced chemical vapor deposition process. Therefore, any copper oxide layer that covers copper layer is replaced by the silicon phosphide layer and then adhesion between copper and silicon nitride is improved. Moreover, the silicon phosphide comprises two advantages: low resistance than copper oxide and efficiently prevent copper diffuses into surrounding dielectric layer.

An operating method of an electronic apparatus and a touch apparatus are provided. In the method, a touch action by a user on a touch panel is detected through a controller of the touch apparatus, so as to obtain a contact region touched by the touch action on the touch panel. Subsequently, whether the touch action includes a palm touch is determined based on a size of the contact region. Under the situation that the touch action includes the palm touch, palm touching information corresponding to the palm touch is transformed into mouse controlling information through a mouse simulating device of the touch apparatus. Further, the mouse controlling information is sent to a mouse driver through the mouse simulating device, such that the mouse driver executes mouse operation based on the mouse controlling information.
