1991年IEEEGaAs集成电路讨论会概况 Introduction TheIEEEGaAsIntegratedCircuitSymposiumhaslongbeenoneofthemostimportantgatheringsofresearchers,engineers,andindustryexpertsinthefieldofGaAs-basedtechnologies.In1991,thesymposiumwasheldattheSheratonHarborIslandHotelandConventionCenterinSanDiego,California.Thispaperprovidesanoverviewofthemajortopics,presentations,anddiscussionsthattookplaceattheconference,aswellasthelatestdevelopmentsinGaAstechnology. ConferenceHighlights TheconferencewasopenedwithakeynotespeechbyDr.WilliamReillyoftheArmyResearchLaboratory,focusedontheuseofGaAsinelectronicandphotonicdevices.Avarietyoftechnicalsessionsfollowed,coveringtopicssuchasGaAsmaterialsandprocesses,devicephysicsandmodeling,microwaveandmillimeter-waveapplications,digitalintegratedcircuits,andoptoelectronics. OneofthekeythemesthatemergedfromtheconferencewastheincreasingimportanceofGaAsinthetelecommunicationsindustry.ResearcherspresentedarangeofpapersontheuseofGaAs-baseddevicesinhigh-frequencymicrowaveandmillimeter-wavesystems,suchassatellitecommunications,radar,andwirelessnetworks.Inparticular,therewasagreatdealofinterestinthedevelopmentofGaAs-basedtransmittersandreceiversforcellularphonesystems,whichwerejustbeginningtoemergeatthetime. AnotherkeyareaoffocusattheconferencewasthedevelopmentofdigitalGaAsICsforhigh-speeddataprocessingandcommunications.ResearchersdiscussedtheuseofGaAstechnologiesinapplicationssuchasdigitalsignalprocessing,fiber-opticcommunications,andhigh-speedcomputerinterfaces,highlightingtheadvantagesofGaAsovertraditionalsilicon-basedsemiconductors,suchashigherspeedandlowerpowerconsumption. Furthermore,significantadvancesweremadeinthefieldofGaAsoptoelectronics,includingphotodetectorsandlight-emittingdiodes.Researcherspresentedpapersontopicssuchasthedesignandfabricationofhigh-performanceGaAsphotodetectorsforuseinopticalcommunicationsandremotesensingapplications,aswellasthedevelopmentofnovelGaAs-basedLEDswithhighbrightnessandefficiency.
