Abstract:
1. A method of manufacturing an electrophoresis microchip, comprising: (a) manufacturing a channel plate from a silicon on glass wafer having a glass layer and a silicon layer, comprising: (b) manufacturing a reservoir plate from a glass wafer, comprising: (c) combining the channel plate and the reservoir plate after disposing the reservoir plate on the silicon layer of the channel plate; and (d) forming electrodes extending from the reservoir plate to the reservoirs by sputtering after disposing a mask above the channel plate and the reservoir plate combined to each other, wherein after deep reactive ion etching the silicon layer and the glass layer of the silicon on glass wafer channels are formed in the channel plate and an optical slit layer composed of the silicon layer is formed except a region of the channels, and wherein combining the channel plate and the reservoir plate comprises anodic bonding an upper surface of the optical slit layer and a lower surface of the reservoir plate to each other.
