Packaging structure

Abstract

The present invention provides a packaging structure, which includes a first substrate and a second substrate, wherein the upper surface of the first substrate has a predetermined area, and a first sealing ring with a first height is located on the upper surface of the first substrate, and arranged on the periphery of the above-mentioned predetermined area, and connected to the lower surface of the second substrate, a second sealing ring with a second height smaller than the first height is located on the upper surface of the first substrate, and is arranged on the first sealing ring The periphery, and a channel is surrounded by the first sealing ring, and an encapsulant is located in the channel. The encapsulation structure of the present invention can effectively provide adhesion and airtightness, reduce the usage of encapsulation colloid, and avoid contamination of the component area.

Description

【Technical field】 [0001] The present invention relates to a packaging structure, and in particular to a packaging structure that can increase adhesion and airtightness, effectively reduce the amount of packaging glue used, and avoid contamination of the component area. 【Background technique】 [0002] Since electronic components such as semiconductor components, micro-electromechanical components (MEMS), or optoelectronic components have tiny and fine circuits and structures, in order to avoid dust, acid and alkali substances, moisture and oxygen from polluting or corroding electronic components, thereby affecting their reliability And life, the process needs to use packaging technology to provide the above-mentioned electronic components with functions such as power distribution, signal distribution, heat dissipation, protection and support. [0003] Most packaging technologies separate the wafer into independent chips and then complete the packaging process, while wafer-lev...

Problems solved by technology

Although the technical solution disclosed in the Taiwan Patent No. I222705 can effectively control the height of the gap between the two substrates and avoid problems such as contamination of the operating area, the sealing frame glue is a flowable glue with an unfixed volume, so it can be applied on It is difficult to accurately control the coating amount of the closed frame glue on the inner side wall or outer side wall of the gap wall, let alone the use cost of the glue, adhesion and airtightness.
