Protons are entered into a substrate to be analyzed at a proton incident angle larger than 0&#xb0; and smaller 90&#xb0;. Excited by the entered protons and emitted from the substrate to be analyzed, the characteristic X-ray is measured by an energy dispersive X-ray detector and the like. Impurity elements present in the substrate to be analyzed are identified based on the measured characteristic X-ray. The in-plane distribution in the substrate can be obtained by scanning the proton beam. The in-depth distribution can be obtained by entering protons at different proton incident angles. The elemental analysis method can be applied to semiconductor device manufacturing processes to analyze metal contamination or quantify a conductivity determining impurity element on an inline basis and with a high degree of accuracy.

Elemental analysis method and semiconductor device manufacturing method

In the resin film evaluation method and method for manufacturing a semiconductor device applying the resin film evaluation method of the present invention, first, a substrate having a resin film formed on an insulating film with an opening in which the surface of the insulating film is exposed is irradiated with charged energetic particles. Then, the surface potentials of the substrate surface irradiated with charged energetic particles are measured. Based on the measurements, the difference in surface potential between the resin film and the insulating film exposed in the opening is obtained. Based on the difference in surface potential, a physical quantity such as the resin film residue count obtained after a given treatment is predicted. In this way, the degenerated layer formed on the surface of a resin film due to charged energetic particles such as implantation ions can be evaluated in a simple and highly accurate manner.

In a method for fabricating an electronic device including a transistor with a drain extension structure, a correspondence between a size of a gate electrode of the transistor and ion implantation conditions or heat treatment conditions for forming the drain extension structure is previously obtained. This correspondence satisfies that the transistor has a given threshold voltage. After formation of the gate electrode and measurement of the size of the gate electrode, ion implantation conditions or heat treatment conditions for forming the drain extension structure are set based on the previously-obtained correspondence and the measured size of the gate electrode. Ion implantation or heat treatment for forming the drain extension structure is performed under the ion implantation conditions or heat treatment conditions that have been set.
