A combined 20-nm-thick spacer structure of p-doped and undoped GaInAs grown at 300 degrees C prevented excessive amounts of beryllium from diffusing into the AlInAs emitter. This allowed base beryllium doping concentrations up to 10/sup 20/ cm/sup -3/ to be achieved, thereby reducing base resistance and increasing f/sub max/ to 70 GHz. A fifteen-stage ring oscillator utilizing these HBTs demonstrated a gate delay of 15.8 ps. The reduced outdiffusion was confirmed by secondary ion mass spectrometry (SIMS) elemental profiles in addition to electrical measurements.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132721969","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}

SLPE is expected to limit the propagation of dislocations in two ways: the LPE process itself terminates dislocations at the growth interface, and contact between the substrate and the growth material is limited by a selective silicon dioxide mask. Currently, this mask is composed of 5- mu m silicon dioxide strips limiting the contact area to 20- mu m strips of silicon. Single-crystal InP has been grown directly on silicon substrates. A 1-2- mu m nucleation enhancement (NE) layer is grown selectively between the silicon dioxide stripes, directly contacting the silicon substrate. The InP LPE film nucleates from this NE layer and growth proceeds vertically and laterally to overgrow the silicon dioxide mask.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129271087","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 suitability of gate insulator and buffer layers of both AlInAs and InP was investigated. The former has the wider bandgap and will thus give better confinement and lower gate leakage currents, whereas InP has the prospect of reduced trapping and thus of lower noise. The test structures and experimental procedures are described, and the results are discussed. It is found that the lower trap density of InP buffer layers does result in better noise performance if the bias conditions are chosen to minimize the effect of the poorer carrier confinement of InP.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"18 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131352647","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 thermal stability of semi-insulating InP:Ti,Hg is discussed, and synthesis by conventional methods and by liquid-encapsulated Czochralski (LEC) growth is considered. Synthesis and HGF growth under controlled P pressure are then examined. Since the melt is not encapsulated, the P pressure can be adjusted to obtain the optimum melt composition for minimizing defect density, impurity contamination, and twinning. In addition, in situ growth prevents impurity contamination that can results when a growth charge synthesized in one system is transferred to a second system for crystal growth.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126558677","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}

It is shown how the PL intensity from an InP substrate varies after successive steps during four different passivation processes, and the information gained thereby is discussed. An example is presented to demonstrate how SPL measurements can be used to optimize the gate recess step in the realization of InP MISFETs. Two possibilities for the routine inline control of successive steps in the processing of compound semiconductor devices using SPL measurements are described: automatic recognition and counting of defects appearing on SPL images (most of which cannot be revealed by optical microscopy) and analysis of statistical parameters describing the SPL data.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114067816","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}

For example, it is seen that nonequilibrium transport in In/sub 0.53/Ga/sub 0.47/As improves static transistor characteristics such as current gain and minimum lateral dimensions. In addition, the fastest bipolar transistors make use of high velocity Gamma -valley nonequilibrium electron transport in In/sub 0.53/Ga/sub 0.47/As. A thin, highly-doped base with an impurity concentration p>10/sup 20/ cm/sup -3/ has a negligible base transit time and collector transit delay dominates the intrinsic response.
