Title: Semiconductor aligner, projection aligner and formation of circuit pattern
Inventor: KIKUCHI HIROKI
IPC: H01L21/027
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To prevent speckle noise by subjecting a basic wave laser light to phase modulation with a voltage signal having a plurality of frequency components, converting the wavelength thereof into the wavelength of ultraviolet rays, producing an optical path difference from a uniform illuminator and projecting a pattern onto a substrate thereby reducing the coherence of laser light. SOLUTION: Basic wave laser light from an Nd:YAG Q switch laser unit 2 enters a phase modulator 1 and subjected to phase modulation depending on a voltage signal amplified through a high frequency amplifier 5 thus widening the overall spectral width of basic wave laser light. The laser light is delivered to a wavelength converter 3 where spectral width of ultraviolet laser light is widened several times. The laser light is then split through a prism 6 into respective wavelength components and only a specified laser light is transmitted through a slit to a uniform illuminator 7. The laser light is split to set an optical path difference before being recombined thus producing a uniform light having low coherence and generating no speckle noise.
