Definitions
- each element is arranged close to each other, and a plurality of resistors or a plurality of MOS transistors may be arranged close to a capacitor.
- a capacitor, a resistor, and a MOS transistor arranged in such close proximity are formed, for example, they are formed by steps shown in FIGS. 6 and 7. That is, first, the field oxide film 2 is formed in the formation region A R of the resistor R and the formation region A c of the capacitor on the silicon substrate 1, and the thickness 250 ⁇ m is formed in the formation region A TR of the MOS transistor TR.
- a tungsten silicide film 13 and a CAP oxide film 15 are laminated, and a resist film 16 is formed (FIG. 6 (e)).
- a resist pattern 16a for forming a gate electrode of the MOS transistor TR is formed from the resist film 16 by a photolithography process (FIG. 7 (a)).
- a mask pattern 17 for forming a gate electrode is formed from the oxide film 15 and the resist pattern 16a is removed (FIG. 7 (b)).
- etching is performed using the mask pattern 17 for forming the gate electrode as a mask to remove the tungsten silicide film 13, and when the mask pattern 12 for forming the resistor R and the capacitor C is exposed, Etching is performed using the mask pattern 12 and the mask pattern 17 for forming the gate electrode as a mask to remove the polycrystalline silicon film 4 (FIG. 7C). Then, an oxide film for LDD formation for forming an LDD structure is formed, and a side wall 8 is formed by anisotropic etching (FIG. 7 (d)). Finally, heat treatment is performed in an oxidizing atmosphere. A thin oxide film is formed on the exposed silicon substrate 1, and this is used as a mask at the time of ion implantation for forming source and drain diffusion regions (FIG. 7 (e)).
- step of FIG. 7 (e) after forming the side walls 18 by anisotropic etching, heat treatment is performed in an oxidizing atmosphere to form a thin oxide film on the exposed silicon substrate 1.
- the polycrystalline silicon film 4 constituting the resistor R is also oxidized.
- the diffusion level of oxygen as the oxidizing gas is reduced to the level inside the wafer or chip, for example, because the thickness of the oxide film on the resistor R after the formation of the side wall for forming the LDD structure is not uniform. If the variation occurs within the resistor, the thickness of the polycrystalline silicon film 4 varies, and the resistance value differs between the resistors R designed to have the same characteristics. There is a problem that will occur.
- a mask pattern for forming the capacitor, the resistor, and the gate electrode is formed.
- the metal silicide film and the first polycrystalline silicon film are etched using the turn as a mask, and the first polycrystalline silicon film is etched while leaving the metal silicide film under the mask pattern for forming the gate electrode.
- an inorganic anti-reflection film is formed without forming a metal silicide film on the upper layer of the resistor and the capacitor, and a metal silicide film is formed on the upper layer of the gate electrode of the MOS transistor. Further, an inorganic antireflection film is formed thereon.
- an oxide film having a thickness of about 300 to 100 [A] is formed on the polycrystalline silicon film 4.
- each resistor R in the resistor formation region A R and each gate electrode TR-G in the transistor formation region ATR have a uniform width between each resistor R, and a width between each gate electrode TR-G.
- the width can be formed to be uniform, and variations in characteristics between the resistors R and between the transistors TR can be suppressed.
- the SiO 2 film is used as the inorganic anti-reflection film 9 and this is also used as an oxygen impermeable film. It is also possible to apply an iN film.
