Photolithography is a process used in microfabrication to transfer geometric patterns to a film or substrate. The importance of lithography can be appreciated in two ways. First, due to a large number of lithography steps needed in Integrated Circuits (IC) manufacturing, lithography typically accounts for about 30 percent of the cost of manufacturing. Second, lithography tends to be the technical limiter for further advances in feature size reduction and thus transistor speed and silicon area.

Although lithography is certainly not the only technically important and challenging process in the IC manufacturing flow, historically, advances in lithography have gated advances in IC cost and performance. The main core of any lithography device is its exposure system. Because the minimum feature size that can be transferred with high fidelity to a resist film on the surface of the wafer is highly related to the wavelength of the light source. In this product, the vacuum pump has been used to hold the wafer onto the chuck.

Application

  • Fabrication of Integrated Circuits (IC), data storage devices, miniaturized sensors, MEMS and NEMS
