Abstract:
A method for forming a pattern of a semiconductor device is provided to avoid a leakage current of a floating gate electrode by generally reducing strong tensile stress working on a floating gate conduction layer pattern. A gate insulation layer and a floating gate conduction layer are formed on a semiconductor substrate(100). The semiconductor substrate, the floating gate conduction layer and the gate insulation layer are etched to form a floating gate conduction layer pattern, a gate insulation layer pattern and a trench(106). A first insulation layer(108) is formed on the resultant structure to fill the trench and cover the floating gate conduction layer pattern. A second insulation layer(110) is formed on the first insulation layer. The first insulation layer is an SOG(spin on glass) layer including a polysilanzane-based material, and the second insulation layer is a layer including compressive stress. The process for forming the first insulation layer can include a soft-bake process and an annealing process that are performed on the first insulation layer.

A vertical furnace device is provided to reduce loss of wafers by preventing the deterioration due to breakdown of a wafer. A thermocouple sensor tube(31) is fixed at one side of an inner surface of a single tube(12) by performing a welding process. The thermocouple sensor tube and the single tube are formed with one body. A hole is formed at a lower part of the single tube. The thermocouple sensor tube is protruded through the hole of the single tube to the outside of the single tube. The thermocouple sensor tube is bent and extended from the outside of the single tube to a top part of the inner surface of the single tube. A thermocouple sensor(32) is installed at the bent and extended parts of the thermocouple sensor tube.
