First protective films are formed to cover side surfaces of gate electrode portions. In an nMOS region, an extention implantation region is formed by causing a portion of the first protective film located on the side surface of the gate electrode portion to function as an offset spacer and using the offset spacer as a mask, and then, cleaning is done. Since silicon nitride films are formed on surfaces of the first protective films, the resistance to chemical solutions is improved. Furthermore, second protective films are formed on the first protective films, respectively. In a pMOS region, an extention implantation region is formed by causing a portion of the first protective film and a portion of the second protective film located on the side surface of the gate electrode portion to function as an offset spacer and using the offset spacer as the mask, and then, cleaning is done.

An article visual inspection apparatus capable of detecting that the surface conditions of an article are so inferior as to render the article unusable as a product and rejecting the same as a defective article by inspecting the article for external defects, occurring on the surface of the article, such as streaks, dice marks and rough surfaces of an aluminum extruded shape. The visual inspection apparatus comprises an imaging device (1) for imaging the surface of the article, and an image processing device (3) for capturing the picked up image. The image processing device (3) has a plurality of image processing units that compare a captured image with a set judging reference value to evaluate the result, whereby the quality of surface conditions is evaluated based on external defects such as streaks, dice marks and rough surfaces of an aluminum extruded shape, and evaluations by the respective image processing units are weighted by a weighting unit to thereby comprehensively judge whether to accept or reject the article.

A long life ferroelectric memory device using a thin ferroelectric film capacitor as a memory capacitor is obtained by disposing one or a plurality of degradation preventive layers on an upper protection electrode and an upper electrode 8 and a degradation preventive layer at the boundary of ferroelectric layer 7 /electrodes 6, 8, or providing a step of decreasing a modified layer at the boundary of ferroelectric layer 7/upper electrode 8. This provides a thin ferroelectric film capacitor which is subjected to less fatigue and imprinting and which has less degradation of the ferroelectric characteristic, thereby to attain a long life ferroelectric memory device.
