"Miniaturization" = to make a thing extremely fine and small, "microprocess technology" = technology to process something ultrafinely

The continuing evolution of electronics equipment in our daily lives is dependent on “miniaturization.” With the development of miniaturization, many everyday electronics equipment have become thinner, lighter, smaller, more stylish, and more convenient to use.

The cellular phone is one example.

In the 1980s, the first cellular phones appeared in Japan, they were so big you had to sling them over your shoulder; now the phone is palm-sized.

Along with such technological development, the cellular phone has now incorporated the functions such as a camera and a television; we now use our phones in more ways, and in more life situations than ever before.

"The case must be thinner, lighter and smaller, but we want more functions."

In order to fulfill these demands all the hidden parts inside a product must be downsized and have higher functionality to be crammed inside. The key components that allow such drastic downsizing are the very small and highly integrated semiconductors, such as IC and LSI.

In manufacturing such semiconductors,

microprocess technology plays a very important role.

Microprocess technology will help shape a better future.
