MATERIALS FOR SEMICONDUCTOR DEVICES. A STUDY OF PATENTS AND PATENT APPLICATIONS
This patent survey is the result of a comprehensive study of United States, British, German, French and European patents, patent applications and other literature on semiconductors, published since about 1975, and classified in accordance with International Patent Class H 01 L 29, sub-classes /14 to /28, relating to semiconductors, the classification being based on the inorganic and organic materials they are made of, and comprising about 250 basic publications. Although germanium and silicon are by far the most commonly used elements in modern semiconductor devices, other materials, such as those of organic origin, are being applied to an increasing extent. It should be mentioned that the classification of semiconductor materials in accordance with the Periodic System of elements has some drawbacks. Inventors, as a rule, mention the use of various elements, stating the particular group of the system to which they belong, without, however, indicating them specifically. This makes the classification of the respective material rather difficult.
