Recently, as the manufacturing technology of semiconductors and the application fields of electronic products using semiconductors have expanded, the need for compound semiconductor wafers that implement a wide variety of single components in one wafer to perform various functions is increasing. 》 In this way, the function of the memory chip and the micro-controller or the control function of the specific function according to the application purpose can be realized in a semiconductor wafer while saving the production cost of the semiconductor wafer and reducing the volume, and can be used.

However, when a composite wafer is manufactured under a single element such as a resistor and a capacitor, the operation characteristics of the flash memory cell are not as good as those in other cases, and a disadvantage that high-speed operation cannot be caused. In order to improve this disadvantage, a resistor body using a high-concentration impurity field frequently used in a semiconductor direct circuit (such as an active field of n- or europium) and a MIM structure (such as 'Stacked, channeled, cylindrical, etc.) capacitors are directly applicable to the technology for manufacturing composite semiconductor wafers with flash memory.

In the case of composite wafers, the engineering variables at the time of resistance formation become larger and the resistance values of the memory cells become unequal, so that resistors and capacitors are sensitive to input voltage and external temperature changes, so there are precision semiconductor products.

Fifth, the invention description (U) process is performed in the same way as the first embodiment, so the parts different from the first embodiment are mainly described in the manufacturing method. Here, for convenience, the process of this embodiment is divided into seven stages to explain. The first stage is: as shown in FIG. 12, an open insulating film 204 is formed in the memory cell forming section a; the peripheral circuit section (electrical, The part b and the capacitor formation part c), after the semiconductor substrate 2000 having the field oxide film 202 formed thereon, is sequentially formed of the first conductive film 206 of the polysilicon mesh and the anti-cure film (not shown). A photosensitive film pattern (not shown) is formed thereon so that the surface of the oxidation preventing film of the memory cell forming portion is exposed to a specific portion. The photosensitive film pattern is used as a mask to etch the oxidation prevention film. After removing the photosensitive film pattern, an oxidation process is performed to selectively form the isolation of the thermal oxidation film material only in the memory cell formation portion that is not protected by the oxidation prevention film. The insulating film 212 is then removed from the oxidation preventing film. The first stage is: as shown in FIG. 13 ′, only the resistance forming portion b and the capacitor forming portion on the first conductive film 206 are formed, and the photosensitive film pattern 21 is selectively formed. The third stage of the printing of the staff consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is: as shown in FIG. 14, using the isolation insulating film 212 and the photosensitive film pattern 210 as masks, and etching the entire area of the memory cell formation section a and the peripheral circuit section. After the first conductive layer 206, the photosensitive film pattern 210 is removed. As a result, a floating gate 206a made of a silicone material and an isolation insulating film 212 were formed in the single memory cell formation portion a; a resistance line 206b made of a silicone material was formed in the resistance formation portion b; a polysilicon was formed in the capacitor formation portion. The first electrode terminal 206c is made of a material. The fourth stage is: as shown in FIG. 15, in order to form the floating gate 206a and the control gate formed thereafter and the insulating film used in the transistor gate insulating film, an oxidation process is performed. As a result, the memory cell forming portion is adapted to the Chinese National Standard (CNS) A4 specification (2 丨 〇Χ 2ί »7 common trend) at the two edges of the insulating insulating film 212 and the two sides of the floating gate 206a. ~ Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Λ7 H7 V. Description of the invention (U) The gate insulating film 204 on the wall is formed on the insulating film 216 (thickness of about 50 ~ 200A) of the oxide film material used in the tunnel insulating film ); The resistance forming portion b and the capacitor forming portion c, an insulating film 216 (thickness of about 50 to 200 A) made of an oxide film is formed on the entire surface of the resistance line 206b and the first electrode terminal 206c. The fifth stage is: as shown in 16), 'a floating gate 206a including an insulating film 216 and an isolation insulating film 212 formed on the upper side, and an insulating film 216 and a resistance line 206b formed on the entire surface, and the first The entire substrate 200 of the electrode terminal 206c is formed as a second conductive film having a thickness of about 100-2000A in a polyketone material. The reason why the second conductive film is formed in this manner is that in addition to forming the first electrode terminal 206c for the control gate and capacitor of the memory cell, other second electrode terminals are formed. Next, a photosensitive film pattern 210 is formed on the second conductive film to define a portion for forming a control gate and a portion for forming a second electrode terminal, and then it is used as a mask to dry-etch the second conductive film. In this process, the resistance forming portion b of the peripheral circuit portion is not protected by the photosensitive film pattern, so the opposite side of the surface of the insulating film 216 on the resistance line 2015 is exposed, and the capacitor forming portion c only exposes the non-photosensitive film pattern. The surface of the insulating film 216 of the portion protected by 210. As a result, a control gate 208a made of a silicone material is formed in the memory cell formation portion a; and a second electrode terminal 208c made of a polysilicon material is formed in the capacitor formation portion c of the peripheral circuit portion. That is, it can be known from the foregoing formula that the resistance wire 206b and the first electrode terminal 206c of the capacitor are formed of the same material as the floating gate 206a; the second electrode terminal 208c of the capacitor is formed of the same material as the control gate; The dielectric film used as a capacitor is formed by an insulating film 216 made of an oxide film.

Next, an interlayer insulating film 224 including a contact hole is formed A1 or Cu alloy bit line 226 * to complete this project. When manufacturing non-electrical semiconductor elements according to this process sequence, it is not necessary to form another dielectric film during capacitor manufacturing, so it is better than the first In the case of the embodiment, the effect of engineering simplification and cost reduction can be obtained. Also, at this time, except that the dielectric film used as the capacitor is made of an oxide film, the rest is the same as that suggested in the first embodiment.
