Brand itsva chaiyo yepakutanga IC stock Yemagetsi Zvikamu Ic Chip Tsigira BOM Service TPS62130AQRGTRQ1

1.

Kana taziva kuti IC inogadzirwa sei, inguva yekutsanangura magadzirirwo ayo.Kugadzira dhizaini yakadzama negaba rekupfapfaidza repende, tinoda kucheka mask yekudhirowa toiisa papepa.Zvadaro tinosasa pende papepa uye tinobvisa mask kana pende yaoma.Izvi zvinodzokororwa kakawanda kuti zvigadzire maitiro akanaka uye akaoma.Ini ndakagadzirwa zvakafanana, nekurongedza zvidimbu pamusoro peumwe neumwe mukuita masking process.

Kugadzirwa kweICs kunogona kukamurwa kuita 4 matanho akareruka.Kunyange zvazvo matanho chaiwo ekugadzira angasiyana uye zvinhu zvinoshandiswa zvingasiyana, mutemo mukuru wakafanana.Maitiro acho akati siyanei nekupenda, pakuti maIC anogadzirwa nependi obva avharwa, nepo pendi inotanga yakavharwa yozopendwa.Nzira imwe neimwe inotsanangurwa pasi apa.

Metal sputtering: Simbi ichashandiswa inosaswa zvakaenzana pawafer kuita firimu rakatetepa.

Photoresist application: Iyo photoresist zvinhu zvinotanga kuiswa pachifukidziro, uye kuburikidza nephotomask (musimboti weiyo photomask ichatsanangurwa nguva inotevera), mwenje wemwenje unorohwa pachikamu chisingadiwe kuparadza chimiro cheiyo photoresist zvinhu.Zvinhu zvakakanganisika zvinozogezwa nemakemikari.

Etching: Iyo silicon wafer, iyo isina kuchengetedzwa nephotoresist, yakamisikidzwa neion beam.

Kubvisa Photoresist: Iyo yakasara photoresist inonyungudika uchishandisa photoresist yekubvisa mhinduro, nekudaro kupedzisa maitiro.

Mhedzisiro yekupedzisira ndeye akati wandei 6IC machipi pane imwechete wafer, ayo anozochekwa otumirwa kune yekurongedza chirimwa chekurongedza.

2.Chii chinonzi nanometer process?

Samsung neTSMC vari kurwisana nayo mune yepamusoro semiconductor maitiro, imwe neimwe ichiedza kuwana musoro mune yekutanga kuchengetedza maodha, uye yave kuda kuita hondo pakati pe14nm ne16nm.Uye ndezvipi zvikomborero uye zvinetso zvichaunzwa nemaitiro akaderedzwa?Pazasi isu tichatsanangura muchidimbu maitiro e nanometer.

Idiki sei nanometer?

Tisati tatanga, zvakakosha kuti tinzwisise zvinorehwa nanometers.Mumashoko emasvomhu, nanometer ndeye 0.000000001 mita, asi uyu muenzaniso wakashata - mushure mezvose, tinogona kungoona mazero akati wandei mushure meiyo decimal asi tisina pfungwa chaiyo yezvavari.Kana tikaenzanisa izvi nekukora kwenzwara, zvinogona kuve pachena.

Kana tikashandisa mutongi kuyera ukobvu hwembambo, tinoona kuti ukobvu hwembambo hunosvika 0.0001 mita (0.1 mm), zvinoreva kuti kana tikaedza kucheka divi rembambo kuita mitsetse 100 000, mutsetse wega wega. yakaenzana neinenge nanometre 1.

Kana tangoziva kuti nanometer idiki sei, tinoda kunzwisisa chinangwa chekudzikisa maitiro.Chinangwa chikuru chekudzikisa kristaro ndechekukwana mamwe makristasi mudiki chip kuitira kuti chip chisave chikuru nekuda kwekufambira mberi kwetekinoroji.Chekupedzisira, saizi yakaderedzwa yechip ichaita kuti zvive nyore kupinda munharembozha uye kusangana neramangwana kudiwa kwekutetepa.

Tichitora 14nm semuenzaniso, maitiro acho anoreva diki diki inokwanisika waya saizi ye14nm mune chip.
