Reduced extrinsic capacitances, low leakage currents, nearly ideal subthreshold slopes and improved scalability offer several advantages over conventional CMOS circuits, particularly in regard of power consumption and circuit speed In this paper we use the SPICE implementation of our charge sheet model of the thin-film SOI MOSFET to investigate quantitatively the performance of digital SOI CMOS circuits in the voltage range from 1 to 2 V. The charge sheet principle allows us to include the subthreshold range into the simulation without losing the consistency with well established strong inversion models. The calculations are based on a SIMOX process with t/sub of/=20 nm, t/sub b/=80 nm, t/sub ob/=350 nm. The threshold voltages of the n-channel and p-channel transistors are assumed to be 0.4 V and 0.5 V, respectively. Most of the model parameters for both SOI and bulk silicon MOS devices-the latter ones are described with the SPICE Level 3 MOSFET model-have been extracted from numerical device simulations.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130431360","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 major requirements for the starting material are: 1) thin Si layers, 2) low active defect densities, 3) highly uniform layers, and 4) good crystalline and electrical quality. Since the variation in these parameters from wafer-to-wafer and run-to-run can be substantial, it is beneficial to qualify the starting wafers as much as possible before using them in circuit runs. An arsenal of characterization techniques has been developed to do this, emphasizing non-contact, non-destructive methods as much as possible. The methods discussed include: spectroscopic ellipsometry, automatic defect counting, photoluminescence scanning, and surface photovoltage response measurement.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133439480","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}

Fortunately, these contaminants can be removed or neutralized at gettering sites associated with bulk oxygen precipitates and backside defects formed by a doped polysilicon layer. The problem with SIMOX, on the other hand, is the gettering sites are isolated by the buried oxide and additional metals can be introduced during O/sup +/ ion implantation and high temperature annealing. Here, we describe a new gettering process; the removal of metal contaminants from SIMOX using an MBE epitaxial SiGe alloy strain layer grown on a SIMOX silicon film. A SiGe alloy, with the desired germanium concentration and layer thickness, provides a highly strained region that acts as a sink(getter) for metals. With thermal cycling metals diffuse to or are driven into the surface strain layer for later removal. To demonstrate this effect and test the SiGe gettering strain layer effectiveness in SIMOX, we introduced a source of Fe/sup 54/ by implantation which is then diffused into the strain layer with an anneal. We analyzed the resulting material using TXRS (low angle surface reflection total X-ray fluorescence analysis), SIMS (Secondary Ion Mass Spectroscopy), and DLTS (Deep Level Transient Spectroscopy) measured on backgate on n-FET.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123986740","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}

These advantages include increased speed (due to reduced capacitance), dielectric isolation (prevents latch-up), high temperature operation, higher packing density, and enhanced performance in radiation environments. The leading SOI technology today is Separation by Implantation of Oxygen (SIMOX). The performance of devices fabricated in the silicon overlayer is highly dependent on the electrical properties of the buried oxide. A persistent problem with buried oxide materials has been the presence of large numbers of electron traps in the oxide. Several schemes have been tried in order to reduce or eliminate this effect. This study presents the results from implanting supplemental oxygen into the buried oxide. Avalanche electron injection was used to determine the density of oxide trapped charge due to electron traps in the buried oxide.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128997851","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}

This results in a comprehensive explanation of the output conductance attenuation with increasing gate voltage (V/sub gs/). Analysis of displacement current effects, SH and impact ionization on transient device operation. Application to device modeling: proposal of a method for the parameters extraction that takes into account the nonlinear distortion of static output characteristics due to the SH phenomenon.
