Abstract

Intended is to manufacture a semiconductor device including a shallow trench element separating region and an inter-layer insulating film of a multi-layered structure. A method for manufacturing the semiconductor device has to use a CMP repeatedly, but this CMP itself takes a high cost so that the manufacturing cost is raised by the repeated uses of the CMP. The insulating film to be used in a shallow trench (ST) element separating region and/or the inter-layer insulating film as the lowermost layer is exemplified by an insulating coating film, which can be applied by a spin-coating method. This insulating coating film has such a composition as is expressed by (CH3)nSiO2-n/2)x(SiO2)1-x (wherein n = 1 to 3, and 0 ≤ x ≤ 1.0), and a film of a different specific dielectric constant k is formed by selecting a heat-treatment condition. Moreover, an STI element separating region can be formed by modifying the insulating coating film completely into an SiO2 film, and the inter-layer insulating film of the small dielectric constant k can be formed by making it into an incompletely modified state.

Abstract

Disclosed is an antifouling base for printing which exhibits self-cleaning properties for a long time due to photocatalytic activity. Also disclosed are a printed matter using such an antifouling base and a printed body. Specifically disclosed is an antifouling base for printing which is characterized in that a photocatalytically active layer is arranged on one side of an organic base via an activity blocking layer and the other side of the organic base serves as a printing surface.

Abstract

An antifouling printing sheet characterized by having a hydrophobic antifouling layer formed on one side of a transparent base sheet and a printing surface on the other side, a printed object having a printed antifouling printing sheet, a printed body. The antifouling printing sheet has a self-cleaning capability thanks to a photocatalyst activation action over a long period of time. A printed object and a printed body using the sheet are also provided.

Abstract

An agricultural plastic tunnel cultivation frame which is an arcuate frame comprising a long member containing fiber-reinforced synthetic resin and consisting of a bent portion and a body portion, characterized in that the cross-section of the bent portion is different from that of the body portion and the ratio ⏧Rm/Rf] of the rigidity (Rm) of the body portion and the rigidity (Rf) of the bent portion is 2.0-4.0. A method for producing a frame having a cross-section of three-layer structure forming an arch by a ceiling portion, a bent portion, an erected portion and an underground buried portion, and a plastic tunnel cultivation frame made of fiber-reinforced resin and capable of forming an inverted U-shaped tunnel are also provided.
