Wafer ya semiconductor ni iki?
Wafer ya semiconductor ni ikintu cyoroshye, kizengurutse ibice bya semiconductor bikora nk'ishingiro ryo guhimba imiyoboro ihuriweho (IC) nibindi bikoresho bya elegitoroniki. Wafer itanga ubuso bunoze kandi bumwe bwubatswe kubintu bitandukanye bya elegitoroniki.
Igikorwa cyo gukora wafer gikubiyemo intambwe nyinshi, zirimo gukura kristu nini nini yikintu cyifuzwa cyifuzwa, gukata kristu muri waferi yoroheje ukoresheje icyuma cya diyama, hanyuma ugasiga kandi ugasukura waferi kugirango ukureho ubusembwa cyangwa umwanda. Wafer yavuyemo ifite ubuso buringaniye kandi bworoshye, nibyingenzi mubikorwa byo guhimba nyuma.
Wafers zimaze gutegurwa, zihura nuruhererekane rwimikorere ya semiconductor, nka Photolithography, etching, deposition, na doping, kugirango habeho uburyo bukomeye nibice bisabwa kugirango hubakwe ibikoresho bya elegitoroniki. Izi nzira zisubirwamo inshuro nyinshi kuri wafer imwe kugirango habeho imirongo myinshi ihuriweho cyangwa ibindi bikoresho.
Nyuma yo guhimba inzira irangiye, chip imwe kugiti cye itandukanijwe no gushushanya wafer kumurongo wateganijwe. Chipi yatandukanijwe noneho irapakirwa kugirango ibarinde kandi itange amashanyarazi kugirango yinjize mubikoresho bya elegitoroniki.
Ibikoresho bitandukanye kuri wafer
Wafers ya Semiconductor ikorwa cyane cyane muri silikoni imwe ya kirisiti kubera ubwinshi bwayo, ibikoresho byiza byamashanyarazi, hamwe no guhuza nibikorwa bisanzwe byo gukora igice cya kabiri. Ariko, bitewe nibisabwa byihariye nibisabwa, ibindi bikoresho nabyo birashobora gukoreshwa mugukora wafer. Dore ingero zimwe:
