Computers have been finding their ways into everyday life and contributing to affluence, safety and personal convenience, as well as responding to progress towards a information society, IT society or ubiquitous society. Computers, which have been supporting social changes, began to change the social structure in the 1980s, when integrated semiconductors were developed and the speed of computers was rapidly enhanced. Current computers and high-speed servers contain many small ceramic capacitors mounted on circuit boards, but their shells are mainly made of resin and metallic materials. Previously, when priority was also placed in areas where components were mounted as well as semiconductors, ceramics were sometimes used as the base material of the main circuit board. A number of electronic ceramics were introduced in response to the ceramics boom from the mid 1980s to the early 1990s. In this chapter, the ceramics intended for computers are explained in detail.
