The current transport is analyzed by considering the transmission velocity at the contact and the drift and diffusion of minority carriers in the implanted layer. The computed result shows quantitatively how ion-implantation can suppress the thermionic emission and minimize the dark saturation current. Ion-implantation also makes the structure insensitive to surface conditions of the semiconductor.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126713146","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}

P-channel insulated-gate gallium antimonide field-effect transistors (GaSb MISFETS) were fabricated and characterized in a wide range of operating temperatures. Such devices are important as basic building blocks for self-scanned 1.8µm imagers for night vision applications. The GaSb MISFETS are planar, closed-geometry devices. The GaSb substrates are oriented and Te-doped to ND ≈ 2×1017cm-3. The source and drain were formed by either Be-implantation or Zn-diffusion. Aluminum is used for both gate electrode and source and drain contacts. Low temperature pyrolytic silicon dioxide was used as gate insulator. The GaSb MISFETS are enhancement devices which follow the ideal MOSFET current-voltage characteristics (i.e., ID α (VG-VTH)2). The threshold voltages vary linearly from ∼ 0 volts to -14 volts as temperature decreases from 300K to 12K. Surface hole mobility of 188 cm2/V-sec was obtained at 300K.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126521421","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 914H operates over a band of from 30 to 31 GHz with less than 1 dB of gain variation over the entire 1 GHz hot band. A very high basic efficiency of 18% at center band has been achieved. Tube features include air cooling, PPM focusing, mod anode electron gun, depressed collector, and poker chip windows. A unique mechanical configuration in which the magnetic focusing structure is added externally to the vacuum envelope was used to fabricate the RF circuit. Cavity design and circuit configuration were developed by exploiting a number of computer design programs. The circuit configuration is a two-section design.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122502657","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}

Results of this investigation indicate that the deleterious effects of metallically decorated crystal defects can be successfully minimized by the design of proper impurity gettering cycles. Furthermore, it has been shown that the resulting p-n junction and MOS reverse-bias leakage currents of optimally processed structures are solely dominated at elevated temperature (T≥40°C) by the inherent diffusion currents (Ea≈1.1 eV). This type of leakage current is not only a function of the Si substrate parameters, but is also area and geometry dependent; and the implications of this upon RAM design, layout, and testing are discussed.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122104643","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 techniques provided a novel production method for the advanced self-aligned MOST, which are especially suitable for super short channel MOS FET. Two closely spaced photoresist walls, which are photolithographically formed on a silicon wafer, protect the narrow region between the walls against the obliquely incident ion beams. By applying this shadowing effect to ion beam etching and the ion implantation process, the positions of the source, drain, gate and their electrodes can at last be delineated by only a single photomask or one step electron beam exposure. This process will reduce the dimensions of MOS FET, resulting in further integration in MOS LSI. By using the MSA process procedure, poly silicon gate MOS FETs with a gate length of 1µm to 3µm are fabricated and tested. These transistors show good performance.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"376 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124697118","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 PbTe comes from Czochraslki single crystals, annealed to lower the carrier concentration. The insulator layers are e-beam deposited Al2O3and MgO. The C(V) curves of these MIS were checked at 77 K. The p-type semiconductor is depleted at zero bias and the flat-band voltage is from 4 to 10 volts for 1500 A° of insulator. The curves indicate a PbTe carrier concentration near 1016cm-3, in agreement with junction characteristic measurements on the same wafers. Transient capacitance measurements on these MIS capacitors give a transient or storage time of 1 to 5 ms, with a 77 K background. Measurements of conductance and variation of conductance with frequency give a lifetime in PbTe of 0,8 to 2 ns.
