Rolling na-ezo aka na usoro egweri dayameta mpụta nke mkpanaka silicon otu kristal n'ime otu mkpanaka kristal nke dayameta achọrọ site na iji wiil egweri diamond, na-egweri ebe ntụaka dị larịị ma ọ bụ idobe oghere nke otu mkpanaka kristal.
Ebe dịpụrụ adịpụ nke otu mkpanaka kristal kwadebere site na otu ọkụ kristal adịghị mma ma dị larịị, na dayameta ya dị ukwuu karịa dayameta nke silicon wafer ejiri na ngwa ikpeazụ. Enwere ike nweta dayameta mkpanaka mkpara site na ịpịgharị dayameta dị n'èzí.
Igwe igwe igwe na-akpụgharị nwere ọrụ nke igwe ihe ntụaka dị larịị ma ọ bụ idobe oghere nke mkpanaka silicon single crystal, ya bụ, iji mee nnwale ntụzịaka n'otu mkpanaka kristal nwere dayameta achọrọ.

N'ozuzu, otu mkpanaka kristal nke nwere dayameta nke na-erughị 200mm na-eji ebe ntụnyere ọnụ ọnụ dị larịị, na otu mkpanaka kristal nwere dayameta nke 200mm na karịa na-eji oghere idowe. Otu mkpanaka kristal nwere dayameta nke 200mm nwekwara ike iji ebe ntụaka dị larịị mee ka ọ dị mkpa. Ebumnuche nke otu kristal mkpara nghazi ntụaka n'elu bụ izute mkpa akpaghị aka n'ọnọdu ọrụ nke usoro akụrụngwa na integrated sekit n'ichepụta; iji gosi nhazi kristal na ụdị conductivity nke silicon wafer, wdg, iji kwado njikwa mmepụta; isi n'ọnọdu nsọ ma ọ bụ n'ọnọdu uzo bụ perpendicular ka <110> direction. N'oge usoro nkwakọ ngwaahịa mgbawa, usoro dicing nwere ike ime ka mgbawa eke nke wafer, na itinye ya nwekwara ike igbochi ọgbọ nke iberibe.
Ebumnuche bụ isi nke usoro okirikiri gụnyere: Imeziwanye mma elu: Ịgbagharị nwere ike wepu burrs na enweghị isi n'elu silicon wafers ma melite ire ụtọ nke silicon wafers, nke dị ezigbo mkpa maka fotolithography na-esote na usoro etching.
