1.Dhizaini ye chip.

Nhanho yekutanga mukugadzira, kuisa zvinangwa

Nhanho inonyanya kukosha muIC dhizaini ndeyekutsanangurwa.Izvi zvakafanana nekusarudza kuti ingani makamuri uye yekugezera yaunoda, ndeapi makodhi ekuvaka aunoda kutevedzera, uye woenderera mberi nedhizaini mushure mekunge waona mabasa ese kuitira kuti usazopedza nguva yakawedzerwa pane zvinotevera zvinogadziriswa;IC dhizaini inoda kuenda nenzira yakafanana kuti ive nechokwadi chekuti chip chinobuda chinenge chisina kukanganisa.

Nhanho yekutanga mune zvakatemwa ndeye kuona chinangwa cheIC, kuti kuita chii, uye kuseta gwara.Nhanho inotevera ndeyekuona kuti ndeapi maprotocol anoda kusangana, akadai seIEEE 802.11 yekadhi isina waya, zvikasadaro iyo chip haizoenderane nezvimwe zvigadzirwa pamusika, zvichiita kuti zvisakwanise kubatana kune mamwe maturusi.Danho rekupedzisira nderekumisikidza kuti IC ichashanda sei, ichipa mabasa akasiyana kune akasiyana mayuniti uye nekumisikidza kuti mayuniti akasiyana achabatana sei kune mumwe nemumwe, nekudaro kupedzisa kutsanangurwa.

Mushure mekugadzira zvakatemwa, inguva yekugadzira iyo chip chidimbu.Danho iri rakafanana nekudhirowa kwekutanga kwechivako, apo pese pese panoitwa dhizaini kuitira kufambisa kudhirowa kunotevera.Panyaya yeIC chips, izvi zvinoitwa nekushandisa mutauro wekutsanangura hardware (HDL) kutsanangura dunhu.HDL dzakadai seVerilog neVHDL dzinowanzo shandiswa kuratidza zviri nyore mabasa eIC kuburikidza nekodhi yepurogiramu.Zvadaro purogiramu inotariswa kuti yakarurama uye yakagadziridzwa kusvikira yasangana nebasa raunoda.

Matanho emafotomasks, kurongedza chip

Chekutanga pane zvese, zvave kuzivikanwa kuti IC inogadzira akawanda mafotomasks, ayo ane mativi akasiyana, rimwe nerimwe riine basa rayo.Dhiagiramu iri pazasi inoratidza muenzaniso wakapfava wephotomask, uchishandisa CMOS, iyo inonyanya kukosha chikamu mumubatanidzwa wedunhu, semuenzaniso.CMOS musanganiswa weNMOS uye PMOS, ichigadzira CMOS.

Imwe neimwe yenhanho inotsanangurwa pano ine ruzivo rwayo yakakosha uye inogona kudzidziswa sekosi yakaparadzana.Semuyenzaniso, kunyora rondedzero yehardware mutauro kunoda kwete kungojairana nemutauro wechirongwa, asiwo kunzwisisa kwemashandiro anoita logic circuits, mashandurudzo anodiwa algorithms kuita zvirongwa, uye kuti synthesis software inoshandura sei zvirongwa kuita magedhi ane logic.

2.Chii chinonzi wafer?

Mune semiconductor nhau, pane zvinogara zvichitaurwa kune machira maererano nehukuru, senge 8" kana 12" machira, asi chii chaizvo chinonzi wafer?Ndeipi chikamu che8" inoreva? Uye ndeapi matambudziko ekugadzira zvimedu zvakakura? Inotevera nhanho-ne-nhanho gwara rekuti chii chinonzi wafer, hwaro hwakakosha hwesemiconductor.

Wafers ndiyo hwaro hwekugadzira marudzi ese emakombuta machipisi.Tinogona kuenzanisa kugadzira chip nekuvaka imba ine Lego zvidhinha, kurongedza iwo dhizaini mushure memutsetse kugadzira chimiro chaunoda (kureva akasiyana machipisi).Zvisinei, pasina nheyo yakanaka, imba inoguma ichave yakakombama uye isingafariri iwe, saka kuti uite imba yakakwana, substrate yakatsetseka inodiwa.Panyaya yekugadzira chip, iyi substrate ndiyo mbichana inozotsanangurwa inotevera.

Pakati pezvinhu zvakasimba, pane yakakosha kristall structure - iyo monocrystalline.Iine pfuma iyo maatomu anorongwa imwe mushure meimwe pedyo kune imwe neimwe, ichigadzira nzvimbo yakati sandara yemaatomu.Monocrystalline wafers saka anogona kushandiswa kuzadzisa izvi zvinodiwa.Zvisinei, kune matanho maviri makuru ekugadzira zvinhu zvakadaro, kureva kucheneswa uye kudhonza kwekristaro, mushure mokunge zvinhu zvinogona kupedzwa.
