The results at nominal bias conditions and room temperature indicate an increase of transconductance with frequency of about 15% occurring primarily between 100 Hz and 1 MHz and an almost constant output resistance. The output resistance, however, has a complex dispersion behavior in the vicinity of the kink effect. The detailed characteristics of the dispersion involve several transition frequencies and associated time constants with different activation energies and having electric field dependence. Transient response measurements with both gate and drain inputs give results consistent with the sinusoidal response. The activation energies of the most prominent trapping effects were determined by measuring the time constants or transition frequencies as functions of temperature.<<ETX>>","PeriodicalId":186256,"journal":{"name":"1993 (5th) International Conference on Indium Phosphide and Related Materials","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114472736","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}

Base-collector designs and their effects on the DC characteristics of the DHBTs were investigated. It is found that in the InAlAs/InGaAs/InAlAs DHBT, the unusual large conduction band discontinuity results in a two-dimensional electron gas (2DEG) stored in base-collector abrupt junction. This 2DEG will push the heterojunction spike up and cause a reach-through effect with a InGaAs space layer inserted between the base-collector junction. Junction grading seems to be the only method to remove the effect. For the InAlAs/InGaAs/InAlGaAs DHBT, the smaller the conduction band discontinuity, the less significant is the 2DEG effect. When the discontinuity is smaller than 0.27 eV, the knee-shape and reach-through characteristics disappear.<<ETX>>","PeriodicalId":186256,"journal":{"name":"1993 (5th) International Conference on Indium Phosphide and Related Materials","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116972809","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}

To reduce both the transit time and the charging time of the base-collector junction electrons are collected by a Schottky contact. As a result the transistor must be collector-up. A fully self-aligned process has been developed for collector-up HBTs. This small cross-type HBT exhibits an attractive potential for fast dynamic behavior. Static behavior has been characterized on test structures grown by chemical beam epitaxy. It has been shown that current injected by the emitter-base junction flows mainly at junction perimeter. Also, it has been demonstrated that the extrinsic base must be over-doped by ion implantation to have small enough access resistance to the base for good dynamic behavior. Static current gains up to 50 have measured for the shortest junction perimeters.<<ETX>>","PeriodicalId":186256,"journal":{"name":"1993 (5th) International Conference on Indium Phosphide and Related Materials","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124451207","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 control voltage was applied to the gate through a on chip 5 current k/spl Omega/ mesa resistor to RF isolate the device from the gate supply. The effect of increased gate leakage current on device performance due to the leakage path created by the gate bias resistor is discussed. Three different gate widths of 300 /spl mu/m, 600/spl mu/m and 1200/spl mu/m were investigated to examine the tradeoff between low on state and high off state capacitance. The DC current-voltage (I-V) characteristics as well as small signal scattering parameter (S-parameter) measurement results from 2-20 GHz are presented.

While the OEIC efforts continue, interest is increasing in very high performance systems for analog, digital, and power microwave applications. In the last year, significant improvements in device performance have been accomplished by grading the emitter-base junction and modifying the collector to enhance the breakdown performance.
