IPC: H01L21/027
Filed: 1987-03-10
Abstract: PURPOSE:To improve the heat resistance and dry etching resistance of a resist pattern by irradiating the resist pattern with ultraviolet beams or far ultraviolet beams and executing baking at a high temperature closest to the flow temperature of a resist elevated by the beam irradiation. CONSTITUTION:An Al-Si layer is laminated onto an silicon semiconductor substrate 101 as a wiring material through an insulating layer, a positive type photoresist is applied for shaping the Al-Si layer to a wiring pattern 11, and a resist pattern 12 is formed through exposure and development. The resist pattern 12 is irradiated with far ultraviolet beams on a heating plate and cured, post baking is executed at a temperature closest to the flow temperature of the resist after curing, and the Al-Si layer is reactive ion-etched, using the resist pattern 12 as a mask, thus forming the wiring pattern 11. Accordingly, the resist pattern 12 maintains a shape accurate to a mask pattern, and the wiring pattern 11 is formed to an excellent pattern shape, thus acquiring a fine photoresist pattern having superior heat resistance and etching resistance.

Abstract: PURPOSE:To avoid a surface inferiority caused by cracks or by the insoak of an etchant at the time of treatment of the back of a wafer by making a contact hole on the surface of a wafer before plating in the concave shape in such a depth as to equivalent to the one in which metal interconnection material, etc., are developed CONSTITUTION:A contact hole on the surface of the wafer 21 is formed before plating in the recessed shape 24 in such a depth as to equivalent to the one in which metal interconnection material, etc., are developed on the surface of the wafer 21 by electric plating or deeper. When electric plating is conducted, bumps 25 are formed in normal locations and a plated film 26 is developed at a window 23 of the contact hole. Since the depth of the window 23 is equal to the one in which the bumps 25 are developed, the flat contact hole without any upsurge can be obtained. By this, a surface inferiority caused by cracks or by the insoak of an etchant can be avoided.

Abstract: PROBLEM TO BE SOLVED: To peel toner without using peeling solution etc., by making an image holding and supporting body on which an image constituted of the hot-melt or thermoplastic image forming material is formed heated and brought into contact with an image peeling body, so that the image is peeled and removed. SOLUTION: The image holding and supporting body on which the image constituted of the hot-melt or thermoplastic image forming material is formed is heated and brought into contact with the image peeling body, so that the image is peeled and removed, and the image holding and supporting body is reproduced. That is, the toner can be peeled without using the image peeling solution when the critical surface tension of the image holding and supporting body is >=20 mN/m and <30 mN/m. Since the critical surface tension of the toner is 30 mM/m to 35 mN/m, the toner is transferred to the image peeling body whose critical surface tension is larger then that of the toner when the image peeling body and the image holding are heated and brought into contact with each other.  In order to satisfy this condition, the critical surface tension of the image peeling body is required to be >=30 mN/m, desirably >=35 mN/m.
