科学家指出,材料是人类文明的重要里程碑,历史上的“石器时代”、“青铜时代”、“铁器时代”都是以材料作为时代的主要标志的;材料又是技术进步的物质基础,如果没有半导体材料的工业化生产,也就不可能有今天繁花似锦的计算机科学和计算机工业。 新材料的崛起,促进了新器件的诞生,随着计算机科学技术的突飞猛进,反过来又对集成器件提出更高的要求。纵观各代电子计算机的发展,就可以发现:在真空管中,电子的发射源于金属材料,制成的门电路运算速度慢,而且产生大量的热量,限制了工作寿命;在以半导体为材料的晶体管以及各
Scientists point out that material is an important milestone in human civilization. Historically, “Stone Age”, “Bronze Age,” and “Iron Age” all took the material as the main symbol of the times. Material was also the material basis for technological progress. The industrial production of semiconductor materials, there can not be today’s blossoming computer science and computer industry. The rise of new materials to promote the birth of new devices, with the rapid advances in computer science and technology, in turn, put forward higher requirements for integrated devices. Throughout the development of all generations of electronic computers, you can find: in the vacuum tube, the emission of electrons from the metal material, made of the gate circuit slow operation, and generate a lot of heat, limiting the working life; in the semiconductor as a material The transistor as well as each
