Method of fabricating X-ray mask and method of fabricating semiconductor device using the X-ray mask
Patent number: 7197108Abstract: In fabricating an X-ray mask, a chromium oxide film serving as an etching stopper is formed on a diamond film serving as an X-ray transmitter. Then, a diamond layer serving as a first X-ray absorber is formed on the chromium oxide film. Thereafter, a tungsten layer serving as a second X-ray absorber is formed on the diamond layer. Consequently, the diamond layer and the tungsten layer form an X-ray absorber having a laminated structure. When the X-ray absorber has a laminated structure including substances having different compositions, the transmittance and the phase shift quantity of the overall X-ray absorber can be readily adjusted. Thus, a method of fabricating an X-ray mask providing improved resolution of the pattern of a semiconductor device or the like is obtained.Type: GrantFiled: July 28, 2003Date of Patent: March 27, 2007Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroshi Watanabe, Koji Kise, Kenji Itoga -
Patent number: 6922458Abstract: A resist is on a substrate with a lower layer film between the resist and the substrate. The lower layer film includes chemical elements and the element absorbing the largest amount of x-rays is carbon. The thickness of the lower layer film is determined by considering the influences of secondary electrons from the substrate and the carbon of the lower layer film. The resist includes chlorine, or a similar element, having a specific absorption edge. Under such conditions, the average wavelength of x-rays absorbed in the resist is in a prescribed range. In this way, in x-ray exposure, blur caused by secondary electrons is suppressed using a wavelength region of relatively shorter wavelengths.Type: GrantFiled: September 16, 2003Date of Patent: July 26, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Koji Kise, Hiroshi Watanabe
