Iminyaka eyishumi yokulala
Ngo-2013, ibhodi yabaqondisi bakwaRenesas yavuselelwa, izikhulu eziphezulu zezinkampani ezinkulu zezimoto, iToyota neNissan, kanye noHisao Sakuta, onolwazi olunzulu enkampanini yokuhlinzeka ngezingxenye zezimoto, wabiza i-CEO entsha, okubonisa ukuthi kukhona ushintsho olukhulu oluseduze. .
Ukuze ehlise umthwalo, u-Sakuta Hisao unqume ukunikeza u-Renesas "ukunciphisa umzimba".Ukudilizwa esikalini kwabantu abangu-2,000 kumane kuwukuthakazelisa, ibhizinisi elingenanzuzo ngamunye ngamunye ukuzwa umoya obandayo:
Ibhizinisi lemodemu ye-LTE yezingcingo eziphathwayo ze-4G zathengiswa ku-Broadcom, imboni yezinzwa ze-CMOS yamakhamera omakhalekhukhwini yathengiswa kwa-Sony, kanye nebhizinisi elibonisa umshayeli we-IC wezibonisi lathengiswa kuma-Synaptics.
Uchungechunge lokudayiswa lusho ukuthi i-Renesas isiphumile ngokuphelele emakethe yama-smartphone, iphinde igxile emandleni ayo endabuko: ama-MCU.
I-MCU ngokuvamile yaziwa ngokuthi i-microcontroller, futhi isimo sohlelo lokusebenza esikhulu kunazo zonke ezezimoto.I-MCU yezimoto ibilokhu iyibhizinisi elinenzuzo futhi elinenzuzo kakhulu kwaRenesas, ethatha cishe u-40% wemakethe yomhlaba.
Igxila kabusha kuma-MCU, i-Renesas yaphinde yahlangana ngokushesha ngo-2014 ukuze izuze inzuzo yangemva kokusungulwa.Kodwa ngemva kokuxubha amafutha angenamsebenzi, indlela yokwakha imisipha iba inselele entsha.
Kuma-MCU anevolumu encane, ezinhlobonhlobo eziningi, iphothifoliyo yomkhiqizo eqinile iyisisekelo sesisekelo.2015, ukuphothulwa komsebenzi womlando ka-Hisao Sakuta usethathe umhlalaphansi, u-Renesas akazange angenise i-semiconductor, noma uchungechunge lokuhlinzeka ngezimoto u-Wu Wenjing, owazi kahle into eyodwa kuphela: ukuhlanganisa nokutholwa.
Esikhathini esiphethwe yi-Wu Wenjing, ukuthengwa kwe-Renesas okulandelanayo kwenkampani yase-US i-Intersil (Intersil), i-IDT, i-Dialog yenkampani yaseBrithani, ukwenza ama-chips okuphatha amandla, amanethiwekhi angenantambo nama-chips okugcina idatha, ukuxhumana okungenantambo ebhodini elifushane.
Ngenkathi ehlezi eqinile kumphathi we-MCU yezimoto, u-Renesas uphinde wangena emkhakheni wokulawula izimboni, ukushayela okuhlakaniphile, amafoni ahlakaniphile, Iphathi esuka ku-Tesla eya ku-Apple, bonke umholi wenkanyezi.
Uma kuqhathaniswa ne-Renesas, umgwaqo wakwaSony wokululama ube nzima kakhulu, kodwa umbono uyafana.
Umnyombo wohlelo lukaKazuo Hirai lwe-"One Sony" lokuguqulwa yi-Playstation ngaphandle kwemikhiqizo yokugcina, njengama-TV, omakhalekhukhwini, ama-laptops, ukwenza ukuhlanganyela kwe-titular empini kungaba, ukulahlekelwa amaKorea akulona ihlazo.
Ngesikhathi esifanayo, sitshale izinsiza zethu ezilinganiselwe ze-R&D ebhizinisini lokuthwebula izithombe zedijithali, elimelwe ama-chips e-CIS, ukuze sibambe iqhaza ekusakazweni kwamatheminali eselula njengomphakeli wengxenye.
I-CIS chip (inzwa yesithombe ye-CMOS) iyisisetshenziswa se-elekthronikhi esiguqula izithombe ezibonayo zibe amasiginali kagesi, futhi iyingxenye ebalulekile yama-smartphones, ajwayele ukubizwa ngokuthi "phansi".Ngo-2011, ama-iPhone 4s okokuqala ngqa esebenzisa i-Sony IMX145, umqondo we-CIS waqala ukushuba.
Ngomphumela wokubonisa we-Apple, kusukela ochungechungeni lwe-Samsung lwe-S7 kuya kuchungechunge lwe-Huawei lwe-P8 ne-P9, i-chip yakwa-Sony ye-CIS isicishe ibe yimodeli ephambili.
Ngesikhathi u-Sony eqala ukukhipha inzwa yakhe yezithombe ze-CMOS enezitaki ezintathu engqungqutheleni ye-ISSCC ngo-2017, ukubusa kwakungenakuphikwa.
Ngo-April 2018, umbiko wonyaka wakwa-Sony waqeda ishumi leminyaka lokulahlekelwa ngenzuzo yokusebenza ephezulu kakhulu eyake yaba khona.U-Kazuo Hirai, omemezele ukuthi uzokwehla esikhundleni sokuba yi-CEO esikhathini esingengakanani edlule, uveze ukumamatheka obekukade kulindelwe.
Ngokungafani nama-CPU nama-GPU, athembele ekuhlanganisweni ukuze kukhuliswe amandla ekhompiyutha, ama-MCU nama-CIS, “njengama-chips asebenzayo”, awadingi izinqubo ezithuthukisiwe, kodwa anezidingo eziphakeme zokuthembeka nokuqina, futhi ancike kakhulu ekuhlangenwe nakho okuqoqwe konjiniyela kanye nenani elikhulu. inani lolwazi oluyimfihlo ekuklanyweni nasekukhiqizeni inqubo.
Ngamanye amazwi, incike kakhulu ekwenziweni kwezandla.
Uma kuqhathaniswa ne-CIS ephezulu yakwaSony isadinga isisekelo se-TSMC, imikhiqizo kaRenesas 'MCU ibambeke kakhulu ku-90nm noma ngisho ne-110nm, umkhawulo wobuchwepheshe awuphezulu, futhi ukushintshwa kuhamba kancane, kepha umjikelezo wempilo mude, futhi amakhasimende ngeke zishintshwa kalula uma sezikhethe.
Ngakho-ke, nakuba ama-memory chips aseJapane ashaywa yiNingizimu Korea, kodwa ku-analogue chip njengommeleli wenkulumo yezimboni, iJapane cishe ayikaze idlule.
Futhi, eminyakeni yabo eyishumi yokulala, bobabili abakwa-Renesas no-Sony bamukele umlenze owugqinsi owanele ukuze bame kuwo.
Imboni yezimoto yaseJapan yona ngokwayo inosiko “lokungabaniki abantu bangaphandle inyama ngisho nasebhodweni elibolile”, futhi ukuthengiswa kwezimoto zakwaToyota ezibalelwa ezigidini eziyi-10 kunikeze abakwaRenesas ama-oda amaningi.
Ibhizinisi lefoni yeselula yakwaSony, nakuba lihlala lihlala ku-pendulum, kodwa ngenxa ye-chip ye-CIS kunzima ukufaka esikhundleni, ukuze u-Sony akwazi ukuqhubeka etheminali yeselula yesitimela sokugcina ukwenza ithikithi lesiteshi.
Kusukela engxenyeni yesibili ka-2020, ukushoda kwesomiso okungakaze kubonwe kuhlasele umhlaba, izimboni ezimbalwa zivalwa ngenxa yama-chips.Njengesiqhingi ebesinakwa isikhathi eside semboni ye-semiconductor, iJapan isiphinde yaba sesiteji.
