Imyaka icumi yo gusinzira
Mu mwaka wa 2013, inama y'ubutegetsi ya Renesas yavuguruwe, abayobozi bakuru bo mu bihangange by'imodoka Toyota na Nissan, na Hisao Sakuta, ufite uburambe bunini mu bijyanye no gutanga ibice by'imodoka, bahamagaye umuyobozi mukuru mushya, byerekana ko impinduka nini iri hafi. .
Mu rwego rwo koroshya umutwaro, Sakuta Hisao yahisemo guha Renesas mbere "slimming".Abantu 2000 bapima akazi ni appetizer gusa, ubucuruzi budaharanira inyungu umwe umwe kugirango yumve akonje:
Ubucuruzi bwa modem ya LTE kuri terefone zigendanwa 4G bwagurishijwe kuri Broadcom, uruganda rukora sensor ya CMOS kuri kamera ya terefone igendanwa rwagurishijwe na Sony, naho ubucuruzi bwa disikuru IC bwerekana ibyerekanwe bugurishwa muri Synaptics.
Urukurikirane rwo kugurisha bivuze ko Renesas idasohoka rwose ku isoko rya terefone, ikongera imbaraga ku muco gakondo: MCUs.
MCU isanzwe izwi nka microcontroller, kandi ibintu binini byerekana ni imodoka.Automotive MCU yamye nubucuruzi bwunguka kandi bwunguka kuri Renesas, butwara hafi 40% kumasoko yisi.
Kwibanda kuri MCUs, Renesas yahise yisubiraho muri 2014 kugirango igere ku nyungu nyuma yishirahamwe.Ariko nyuma yo gukuraho ibinure bidafite akamaro, uburyo bwo kubaka imitsi biba ikibazo gishya.
Kubito-bito, byinshi-bitandukanye MCUs, ibicuruzwa bikomeye portfolio nurufatiro rwibanze.2015, kurangiza ubutumwa bwamateka ya Hisao Sakuta yagiye mu kiruhuko cy'izabukuru, Renesas ntiyatangije imashini itwara imashanyarazi, cyangwa Wu Wenjing utanga amamodoka, uzi ikintu kimwe gusa: guhuza no kugura.
Ku buyobozi bwigihe cya Wu Wenjing, Renesas yagiye agura isosiyete yo muri Amerika Intersil (Intersil), IDT, isosiyete yo mu Bwongereza Dialog, kugira ngo yishyure imashini zikoresha amashanyarazi, imiyoboro idafite insinga hamwe n’ibikoresho byo kubika amakuru, itumanaho ridafite umugozi ku kibaho gito.
Mugihe yicaye ashikamye mubuyobozi bwimodoka MCU, Renesas yinjiye mubijyanye no kugenzura inganda, gutwara ibinyabiziga bifite ubwenge, terefone zikoresha ubwenge, Ibirori kuva Tesla kugeza Apple, umuyobozi winyenyeri zose.
Ugereranije na Renesas, umuhanda wa Sony wo gukira wabaye mubi, ariko igitekerezo ni kimwe.
Intego ya gahunda yo kuvugurura "One Sony" ya Kazuo Hirai ni Playstation hanze yibicuruzwa byanyuma, nka TV, terefone zigendanwa, mudasobwa zigendanwa, kugira uruhare mu ntambara bishobora kuba, gutsindwa n’Abanyakoreya ntabwo biteye isoni.
Muri icyo gihe, twashora imari mike ya R&D mubucuruzi bwerekana amashusho ya digitale, ihagarariwe na chip ya chip, kugirango tugire uruhare mukuzunguruka kwa terefone ngendanwa nkumuntu utanga ibikoresho.
Chip chip (CMOS ishusho ya sensor) nigikoresho cya elegitoronike gihindura amashusho optique mubimenyetso byamashanyarazi, kandi nikintu cyingenzi muri terefone zigendanwa, zizwi cyane nka "hepfo".2011, iPhone 4s kunshuro yambere ukoresheje Sony IMX145, igitekerezo cya CIS cyatangiye kunanuka.
Hamwe nimikorere ya Apple, kuva muri S7 ya Samsung kugeza kuri Huawei ya P8 na P9, chip ya Sony ya CIS imaze kuba icyitegererezo cyambere.
Mugihe Sony yatangizaga ibyuma byerekana amashusho atatu ya CMOS mu nama ya ISSCC mu 2017, ubwiganze ntibwashoboka.
Muri Mata 2018, raporo ya buri mwaka ya Sony yarangije igihombo cyimyaka icumi ninyungu zikora cyane kurusha izindi zose.Kazuo Hirai, watangaje ko yeguye ku mirimo ye nk'umuyobozi mukuru, hashize igihe kinini amwenyura.
Bitandukanye na CPU na GPUs, zishingiye ku kwishyira hamwe kugirango zongere imbaraga zo kubara, MCUs na CISs, nka "chips imikorere", ntibisaba inzira ziterambere, ariko bifite ibisabwa byokwizerwa kandi biramba, kandi bishingiye cyane kuburambe bwa injeniyeri hamwe nubunini ingano yubumenyi bwa tacit mugushushanya no gutunganya umusaruro.
Muyandi magambo, ishingiye cyane kubukorikori.
Ugereranije na Sony yo mu rwego rwo hejuru ya CIS iracyakeneye uruganda rwa TSMC, ibicuruzwa bya MCU bya Renesas ahanini biguma kuri 90nm cyangwa ndetse na 110nm, urwego rw'ikoranabuhanga ntiruri hejuru, kandi umusimbura uratinda, ariko ubuzima buzaba burebure, kandi abakiriya ntibazaba. gusimburwa byoroshye iyo bahisemo.
Kubwibyo, nubwo Ubuyapani bwibukwa bwakubiswe na Koreya yepfo, ariko muri chip ya analogue nkuhagarariye disikuru yinganda, Ubuyapani ntabwo bwigeze burenga.
Nanone, mu myaka icumi yo kwisinzira, Renesas na Sony bombi bakiriye ukuguru kwinshi bihagije kugirango bahagarare.
Inganda z’imodoka z’Abayapani ubwazo zifite umuco wo "kudaha abanyamahanga inyama ndetse no mu nkono iboze", kandi Toyota yagurishije imodoka hafi miliyoni 10 zahaye Renesas ibicuruzwa byinshi.
Ubucuruzi bwa terefone igendanwa ya Sony, nubwo burigihe muri pendulum, ariko kubera chip ya CIS biragoye gusimbuza umwanya, kugirango Sony ikomeze muri terefone igendanwa ya gari ya moshi iheruka gukora itike ya sitasiyo.
Kuva mu gice cya kabiri cy'umwaka wa 2020, ibura ry’amapfa ritigeze ribaho mu isi yose, inganda nyinshi zahagaritswe kubera chip.Nka kirwa kimaze igihe kititaweho cyinganda ziciriritse, Ubuyapani bwongeye kuri stage.
