Title: Insulation separating composition
Inventor: OZAWA TADASHI
IPC: H01L21/763
Filed: 1981-02-27
Abstract: PURPOSE:To reduce the design margin between elements by a method wherein a P-N junction sideward expansion of which is limited is formed in an insulation region on an integrated circuit by using polycrystal silicon which has different diffusion speed from single crystal silicon. CONSTITUTION:SiO2 film is formed on a whole surface of an epitaxial layer and only poly-silicon portion is exposed by etching. The PN separation is cimpleted by completion of a P type region sorrounding an active region 5 of elements in combination with a P type region of a substrate by forming a P type region by diffusing boron. At that time the diffusion coefficient of the boron in the poly-silicon is sufficiently larger than that in single crystal silicon and the boron is diffused in a short time and approximately into the poly-silicon only, so that an integrated circuit with a small separation region can be obtained by limiting sideward expansion.
