Method of applying adhesive

Abstract

An applying method for an adhesive according to an embodiment includes the following steps. First, gas is exhausted from a first exhaust pipe, so as to eliminate a part of the gas in a closed container. Next, the gas continues to be exhausted from the first exhaust pipe, so as to have the adhesive in the transmission pipeline become bubbled, and also to convey the bubbled adhesive to reach the supply vent. Later, gas is exhausted from the second exhaust pipe and continues to be exhausted from the first exhaust pipe, so as to greatly exhaust the gas in the closed container, and also to increase bubbling in the adhesive. Subsequently, the gas continues to be exhausted from the second exhaust pipe and ceases to be exhausted from the first exhaust pipe, so as to cause the adhesive to reach a gasified state. Also the gasified adhesive is supplied to the closed container from the supply vent, so that the gasified adhesive can adhere to and coat above the SiOlayer. Finally, gas may be exhausted from the first exhaust pipe and ceases to be exhausted from the second exhaust pipe, so that the remaining gasified adhesive in the closed container is pumped out.
