Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 チップレベルでの平坦化を確実に実施するこ とにある。 【構成】 まず、基板1上に配線パターン2を形成した 後(図1(a))、配線パターン2の高さよりも厚くP −TEOSによる絶縁膜3を成膜する(図1(b))。 このように厚く成膜することにより、膜中にボイド4が 形成される。次いで、絶縁膜3の上層部にメカノケミカ ルポリシング(CMP)を施し、研磨表面に、局所的な 溝部4´を表出させる(図1(c))。次いで、この表 面にO 3 −TEOSを薄く成膜する。このO 3 −TEO Sは、局所的な埋め込み性を有しており、溝部4´の内 部にO 3 −TEOS5が埋め込まれ、表面が平坦化され る。 (57) [Abstract] [Purpose] To ensure planarization at the chip level. [Structure] First, after forming the wiring pattern 2 on the substrate 1 (FIG. 1A), the wiring pattern 2 is made thicker than the height of the wiring pattern 2. -The insulating film 3 made of TEOS is formed (FIG. 1B). By forming such a thick film, the void 4 is formed in the film. Then, mechanochemical polishing (CMP) is applied to the upper layer portion of the insulating film 3 to expose the local groove portion 4'on the polished surface (FIG. 1C). Then, a thin film of O 3 -TEOS is formed on this surface. This O 3 -TEO S has a local embedding property, and O 3 -TEOS 5 is embedded inside the groove portion 4 ′ to flatten the surface.
