    摘要: An initial estimated value of a process condition is set, and a structure of an element of a semiconductor device is estimated by a process simulator, after which an estimated value of a physical amount measurement value is calculated. Then, an actual measurement value of a physical amount of the element of the semiconductor device, which is obtained by an optical evaluation method, and a theoretical calculated value thereof are compared with each other, so as to obtain a probable structure of the measured semiconductor device element by using, for example, a simulated annealing, or the like. A process condition in a process for other semiconductor device elements can be corrected by using the results.

    摘要: A thermal cleaning of a substrate that has been subjected to wet cleaning is carried out under a high vacuum atmosphere to remove an oxide film remaining on the substrate. Thereafter, a thermal cleaning is carried out under a hydrogen atmosphere to remove contamination such as carbon or the like. At this time, the oxide film has already been removed and therefore contamination is effectively removed by a relatively low temperature and short duration thermal cleaning. Thus, problems such as the degradation of the profile of the impurity concentration in the impurity diffusion layer which has been formed over the substrate are prevented.
