What is soft-lithography?
So, an alternative and non-photolithographic method that we call soft lithography was developed. Because this method uses a patterned elastomer(e.g. PDMS(Poly DiMethyl Siloxane)) as the stamp, mold, or mask to generate micro-patterns and microstructures, it was titled as 'soft' lithography. As compared with photo-lithography, soft lithography has many kinds of strength.
The lens is used to focus the sectioned UV light down to a smaller area on the chip. The smallest feature size capable of being written on the wafer is a function of the numerical aperture of the lens as well as the wavelength of the light.

마이크로프로세서란 one-chip CPU를 말한다. 과거 일반적인 대형 컴퓨터의 CPU는 하나의 커다란 보드에 수많은 digital IC chip 들로 구성되어 CPU의 기능을 수행하는 반면 마이크로프로세서는 하나의 chip에 CPU의 기능을 수행하는 digital회로를 모두 집적하여 CPU기능을 완전히 수행 할 수 있도록 한 것
patterns of their brain waves, researchers can track the intensity of visceral responses such as anger, lust, disgust, and excitement. The fMRI, on the other hand, uses a giant magnet to track the blood flow throughout the brain as test subjects respond to visual, audio, or even taste cues.
In the field of marketing, scholars have agreed that there are three major trends that are newly arising.
2.2. 배지
(1) 배양기 또는 배지
미생물 생장에 필요한 모든 영양성분이 들어있는 것
필요 이상의 영양분 →미생물 성장에 억제 효과
배양 목적에 따라 →한천(agar)이나 젤라틴(gelatin) 첨가 →고체배지
(2) 배지의 종류에 따른 구분
① 자연배지(Natural medium): 감자나 토마토액 또는 우유처럼 자연
