探讨了硅基气密性封装的可行性,将电镀镍-金镀层的柯伐盖板、密封区金属化的硅基板用金锡焊料片通过熔封形成密封。硅是一种脆性材料,在硅基气密性密封结构中,需要研究气密性封装腔体大小对结构强度的影响(规律),以及可承受的压力。试验结果表明,腔体小于11 mm×27 mm时(腔体高度不限),350μm厚度的硅基板可直接与柯伐盖板密封,密封结构中的硅基板不会碎裂且可承受至少0.1 MPa的压力。

To research the feasibility of one novel silicon hermetic package, welding the cover with nickel and gold surface, silicon substrate surface metalized and Au80Sn20 solder pieces. Need to research the effect of cavity area changes that influence the silicon package’s structure strength and the pressure that package could support, for silicon is a brittleness material. The results showed, when the section acreage of cavity less than 11 mm×27 mm, 350μm thickness silicon substrate can weld with kovar cover directly, and the package can support at least 0.1 MPa pressure while the silicon substrate with no crack.
