However, CMOS devices are not perfect, and performance improvements are constrained by several physical phenomena such as the short-channel-effects, carrier velocity saturation, and resistance/capacitance increase. We perform CMOS-device performance evaluation using an analytical model, in which carrier velocity saturation, diffusion-layer resistance and capacitance, and mobility degradation etc. are taken into consideration, This analysis suggests what the device structures should be. Then, several measures necessary for performance improvements are described, and finally characteristics of the fabricated CMOS devices are introduced.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122468741","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}

A trap-assisted tunneling of carriers from the emitter to the collector through the base potential barrier is suggested as the mechanism responsible for this observed phenomenon. The differences in the temperature dependence of the collector leakage current between SiGe HBTs and Si BJTs is explained by modelling the electron tunneling transition probability from the emitter region to traps located in the neutral-base using SCORPIO, a calibrated 1-D simulator for low-temperature Si/SiGe bipolar transistors.

These devices demonstrate excellent scaling characteristics down to submicron dimensions in both the channel length and the width, which are attributed to the special geometry of the 2D-3D contacts suppressing both the narrow channel effect (NCE) and the drain induced barrier lowering (DIBL). Specifically, when the device was scaled from 1.0/spl times/1.0 /spl mu/m/sup 2/ to 0.8/spl times/0.5 /spl mu/m/sup 2/, output conductance was reduced from 40 mS/mm to less than 1 mS/mm, knee voltage was reduced from 0.75 V to 0.25 V, and the ideality factor was reduced from 1.3 to 1.08, while the threshold voltage became less negative from -0.5 V to 0.3 V as expected. An excellent source-drain breakdown voltage over 10 V, and a current ON/OFF ratio over 105 were also observed. The gate leakage current remains small up to 0.6 V gate bias, demonstrating a good Schottky barrier between the side gates and the 2D electron gas. These characteristics compare favorably with those of a conventional HFET with similar dimensions.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"31 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134550197","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}

The uniformity of the metal deposition along with the compatibility of the fabrication process with standard CMOS technology makes PtSi highly suited for large and high resolution focal plane arrays. To improve the quantum efficiency we have fabricated PtSi Schottky diodes on p-Si with various dry-etched lamellar gratings. The grating periods were 3 /spl mu/m, 4 /spl mu/m and 5 /spl mu/m, and the grating amplitudes were chosen between 300 nm and 1100 nm. The grating structure influences the optical properties of the diode and the absorption in the PtSi layer depends on the polarization of the incoming radiation. For TE-polarized light the E-field vector is parallel to the grating grooves, for the TM-polarization it is perpendicular.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114526429","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}

C/sub bc/, is a key limiter of HBT microwave gain and bandwidth. Our process uses high dose, high-energy ion implantation through the external base layer to compensate part of the heavily doped sub-collector. It also uses the more conventional self-aligned shallow implant to compensate the entire collector underneath the base contact. The total C/sub bc/ of the double implanted HBTs has been reduced by more than 35% with this new technique as compared to devices with shallow implant only. Under proper conditions, the double implantation produces little damage to the base (which can cause an increase in base resistance R/sub B/); thus the RF performance can be significantly improved. An f/sub MAX/ greater than 200 GHz has been obtained, comparable to the best previous reported results in common emitter HBTs.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131949542","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}
