This technology, called DIIP (double-implanted and isolated P-well) CBi-CMOS technology, is characterized by a structure with vertical NPN, PNP and CMOS structures on the same chip. In this structure, a vertical PNP transistor and NMOS transistor are fabricated in a P-well, which is isolated from the P-type substrate by the N+ buried layer and has a deep P+ region created by high-energy ion implantation. This deep P+ region acts as a subcollector for the vertical PNP transistor and as a punch-through barrier from the N+ source/drain of the NMOS transistor to the N+ buried layer.

Dielectric breakdown reliability of ultrathin tunneling oxide for various post-annealing conditions is discussed. The dielectric breakdown reliability of ultra-thin tunneling oxide is degraded by high-temperature post-annealing. The charge to breakdown is reduced drastically with increasing annealing temperature and annealing time. The dielectric breakdown reliability degradation of ultrathin tunneling oxide by post-annealing can be explained by the tunneling oxide thinning and electric field concentration due to the increase of roughness at the polysilicon gate/ultrathin tunneling oxide interface. This increase of roughness is due to the grain growth of the polysilicon gate and viscous flow of oxide, which can be enhanced by increasing the annealing temperature and time","PeriodicalId":441541,"journal":{"name":"Digest of Technical Papers.1990 Symposium on VLSI Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123969024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this result it is shown that a peak in device performance occurs at an effective channel length of approximately 0.22 μm for reliable 3.3 V FOLD NFETs having a gate oxide thickness of 10 nm. Below 0.22 μm, performance actually decreases due to the addition of the very large (LDD) regions (fingers) required to maintain adequate HER. This peak shifts to an effective channel length of ≈0.15 μm for asymmetric 3.3-V-FOLD NFETs. Despite this performance limit, it is found that 3.3 V FOLD NFETs are still faster than scaled 2.5-V single-diffusion NFETs down to 0.25 μm. Although a significant performance advantage has been reported for FOLD n-channel MOSFETs, the fundamental tradeoff between parasitic gate-to-drain capacitance and hot electron reliability inherent to the FOLD structure has yet to be quantified.

In-situ surface analysis has permitted characterization of the precleaned surface, particularly the concentration of oxide and carbon present after different precleaning treatments. The results demonstrate that integration of preclean and oxidation can yield MOS structures with device-quality dielectric breakdown characteristics. Furthermore, they indicate that the role of low-level reactive impurities becomes crucial when using integrated vacuum processing systems.
