Title: Manufacture of high-density metallic gate mos
Inventor: RYO ISEI
IPC: H01L21/768
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to select the thickness of an oxide layer at each section on a wafer, by causing an oxide layer to grow, removing an unnecessary nitride layer, removing a thin oxide layer furthermore, and causing an insulating oxide layer to grow newly. SOLUTION: After the formation of a P-type wafer in a specific region of an N-type wafer 1 for example, a shield layer 60 composed of a thin oxide layer 62 and a nitride layer 64 is formed. After this, two P<+> sections 24 and two N<+> sections 34 are formed, and an oxide layer 66 is caused to grow after that. The thicknesses of the P<+> and N<+> sections 24 and 34 are approximately the same. Furthermore, the nitride layer 64 unnecessary is removed, and only the thin oxide layer 62 is left unremoved. Next, an insulating oxide layer 40 is caused to grow newly to remove the thin oxide layer 62, and the thickness of an insulating oxide layer 41 on the P<+> sections becomes larger than that of an insulating oxide layer 45 on gate sections, and local oxidation can be achieved.  Consequently, it becomes possible to design and control the thicknesses of the P<+> sections, N<+> sections, and gate sections freely.

Filed: 1985-04-19
Abstract: PURPOSE:To reduce a separation region between a collector region and an isolation region by forming a first region having a conduction type reverse to a substrate to the surfaces of all island regions except an emitter region, the collector region and a base region. CONSTITUTION:An epitaxial layer 22 and a buried layer 23 are shaped onto a substrate 21, and an isolation region 24 is formed while penetrating the epitaxial layer 22 so as to surround the buried layer 23. An emitter region 26 and collector regions 27 are shaped in the lateral direction in an island region 25 isolated by the isolation region 24. First regions 28 having a conduction type reverse to the substrate 21 are formed to the surfaces of regions substantially functioning as bases among these regions 26, 27, all island regions except the surfaces of the island region 25 among the regions 26, 27, and these regions 26, 27. Consequently, the spreading of depletion layers generated in a base-collector junction in the surface of the island region 25 and a collector isolation junction can be inhibited without changing the resistivity of the epitaxial layer 22. Accordingly, a clearance A between the collector region and the isolation region can be reduced only by a section corresponding to the inhibition of the spreading.
