Abstract: A power converter that properly copes with the wiring defects on a feedback path is shown. According to a control signal, a power driver couples an input voltage to an energy storage element to provide an output voltage that is down-converted from the input voltage. The output voltage is further converted into a feedback voltage by a feedback circuit, and is entered to an error amplifier with a reference voltage for generation of an amplified error. A control signal generator generates the control signal of the power driver according to the amplified error. The power converter specifically has a comparator, which is enabled in a soft-start stage till the output voltage reaches a stable status. The comparator compares the amplified error with a critical value. When the amplified error exceeds the critical value, the input voltage is disconnected from the energy storage element.

Abstract: A defect-reducing coating method is disclosed, which is characterized by making the coating surface of a sample face the bottom of the coating chamber, so that the sticking particles on side walls of the coating chamber will not fall on the coating surface of the sample during the coating process, thereby a smooth coating layer can be formed on the coating surface of the sample after the coating process is finished.

Abstract: A method for fabricating an NMOS transistor is disclosed. First, a substrate having a gate structure thereon is provided. A carbon implantation process is performed thereafter by implanting carbon atoms into the substrate for forming a silicon carbide region in the substrate. Subsequently, a source/drain region is formed surrounding the gate structure. By conducting a carbon implantation process into the substrate and a corresponding amorphorized implantation process before or after the carbon implantation process is completed, the present invention eliminates the need of forming a recess for accommodating an epitaxial layer composed of silicon carbide while facilitates the formation of silicon carbide from the combination of both implantation processes.

Abstract: Under the first embodiment of the invention, back-end etching is applied to the specimen that needs to be inspected. Its surface is cleaned and mounted on a glass surface with the surface of the poly gate silicide that needs to be inspected being in contact with the surface of the glass. The exposed surface of the sample that is to be examined contains silicon, this silicon is removed. The gate oxide is then removed followed by the removal of the remaining poly of the gate structure. The second embodiment of the invention addresses poly gate inspection by enhanced (top surface of the gate electrode) gas etching of the gate electrode to remove gate oxide and silicon remains from the environment of the silicide. The specimen is etched back to the contact layer using a conventional Chemical Mechanical Polishing (CMP) process. The polished surface of the specimen is next exposed to XeF2, which selectively removes the oxide while the silicide remains in place.
