摘要:
A method of manufacturing a semiconductor device is presented. In one aspect, the method comprises forming conductive and ferroelectric material layers on a semiconductor substrate. The material layers are patterned to form electrodes and a ferroelectric layer of a ferroelectric capacitor, wherein a conductive noble metal-containing polymer is generated on sidewalls of the ferroelectric capacitor. The method also comprises converting the conductive noble metal-containing polymer into a non-conducting metal oxide. Converting includes forming a water-soluble metal salt from the conductive noble metal-containing polymer and reacting the water-soluble metal salt with an acqueous acidic solution to form a metal hydroxide. Converting also includes oxidizing the metal hydroxide to form the non-conducting metal oxide.

A method for manufacturing a semiconductor device. The method comprises forming a metal layer on a silicon-containing layer located on a semiconductor substrate. The method also comprises reacting a portion of the metal layer with the silicon-containing layer to form a metal silicide layer. The method further comprises removing an unreacted portion of the metal layer on the metal silicide layer by a removal process. The removal process includes delivering a flow of an acidic solution to a surface of the unreacted portion of the metal layer, wherein the acidic solution delivered to the surface is substantially gas-free.

A method for making a transistor 20 that includes using a transition metal nitride layer 200 and/or a SOG layer 220 to protect the source/drain regions 60 from silicidation during the silicidation of the gate electrode 90. The SOG layer 210 is planarized to expose the transition metal nitride layer 200 or the gate electrode 93 before the gate silicidation process. If a transition metal nitride layer 200 is used, then it is removed from the top of the gate electrode 93 before the full silicidation of the gate electrode 90.

The present invention is directed, in general, to packaged polishing pads for chemical mechanical polishing of semiconductor wafers and integrated circuits. More specifically, the invention is directed to a method of preparing and packing the pad and the packaging therefor. Prior to placing the pad on a platen and polishing with the pad, a polishing pad having an hygroscopic absorbency is soaked with an aqueous media for a time sufficient to equilibrate the pad. The pad maybe packaged by placement in a sealable moisture tight package after soaking or before soaking along with a sufficient quantity of aqueous media to allow the pad to equilibrate.

The present invention provides a system and method for measuring the surface properties of polishing pads using noncontact ultrasonic reflectance. An ultrasonic probe is located over the polishing surface and configured to both transmit an ultrasonic signal to the polishing surface and receive a modified ultrasonic signal from the polishing surface without contacting the polishing surface. A subsystem coupled to the ultrasonic probe is configured to determine a surface property of the polishing pad from the modified signal.
