Title: Halftone phase shift mask
Inventor: SATO HIROHIKO
IPC: G03F1/32
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to lower side peak intensity without the formation of auxiliary patterns and without degrading resolution by sloping the sectional shape at the flanks of the apertures of the patterns of a halftone light shielding layer to a taper shape. SOLUTION: For example, quartz glass is used as a transparent glass substrate 1 which is the base of a recticle. Such a thin film which inverts the phase of transmitted light 180 deg. with respect to this glass substrate 1 and makes its light transmittance to 4 to 30% is used as the halftone light shielding layer 2 which is commonly used as a phase shift layer. An oxidized film of Cr, a nitrided film of Cr, an oxynitrided film of Cr, SOG(spin on glass) film, MoSi film, etc., are usable for the material of the halftone light shielding layer 2. The film thickness thereof is adequately, for example, 1,000 to 2,000 Å. The sectional shape at the flanks of the apertures of the patterns is sloped to the taper shape and the inside peak is suppressed without the deterioration of the resolution by controlling the angle θ formed by the flanks and the surface of the glass substrate 1.

Filed: 1989-04-25
Abstract: PURPOSE:To obtain a quartz glass body which has sufficient heat resistant strength and does not deform under a high humidity atmosphere by dispersing a specified proportion of heat resistant fine powder such as silicon, carbon, and silicon carbide in quartz glass. CONSTITUTION:Heat resistant material 2 such as silicon, carbon, and silicon carbide is made fine powder or fiber, and dispersed in a quartz glass body.

When the grain diameter of the powder body or the line diameter of the fiber body is large, and the dispersion proportion of the powder body or the fiber body becomes large, cracks are apt to generate, so that it is desirable for dispersion proportion of the powder or the fiber to be less than or equal to 5wt.%, and for the grain diameter to be less than or equal to 100mum. This quartz glass body is used as a boat, a furnace core tube, a conveying jig, and a crucible for pulling up single crystal which are used in high humidity reaction process of wafers.
