Ndị French wetara transistor GAA ọkwa asaa nke echi

Ogologo oge ọ bụghị ihe nzuzo, na site na teknụzụ usoro 3nm, transistor ga-esi na ọwa FinFET kwụ ọtọ gaa na ọwa nanopage kwụ ọtọ na ọnụ ụzọ ámá ma ọ bụ GAA (ọnụ ụzọ-na-gburugburu). Taa, ụlọ ọrụ French CEA-Leti gosipụtara ka enwere ike iji usoro nrụpụta transistor FinFET mepụta transistor GAA dị iche iche. Na ịnọgide na-aga n'ihu nke usoro teknụzụ bụ ihe ndabere a pụrụ ịdabere na ya maka mgbanwe ngwa ngwa.

Ndị ọkachamara CEA-Leti maka VLSI Technology & Circuits 2020 symposium kwadebere akụkọ banyere mmepụta nke transistor GAA-ọkwa asaa (ekele pụrụ iche maka ọrịa na-efe efe nke coronavirus, ekele nke akwụkwọ ngosi nke mechara malite ịpụta ngwa ngwa, ọ bụghị ọnwa mgbe nnọkọ). Ndị na-eme nchọpụta French egosila na ha nwere ike ịmepụta GAA transistors na ọwa n'ụdị dum "nchịkọta" nanopages na-eji nkà na ụzụ a na-ejikarị eme ihe nke a na-akpọ usoro RMG (ọnụ ụzọ ngbanwe ígwè ma ọ bụ, na Russian, ngbanwe (nwa oge) ígwè. Ọnụ ụzọ). N'otu oge, a na-emegharị usoro nkà na ụzụ RMG maka mmepụta nke FinFET transistors na, dịka anyị na-ahụ, enwere ike ịgbatị na mmepụta nke GAA transistor nwere nhazi ọkwa dị iche iche nke nanopage channels.

Samsung, dị ka anyị maara, na mmalite nke mmepụta nke 3-nm ibe, na-ezube na-emepụta abụọ-larịị GAA transistors na abụọ flat ọwa (nanopages) emi odude otu n'elu nke ọzọ, gbara ya gburugburu n'akụkụ nile site a ọnụ ụzọ ámá. Ndị ọkachamara CEA-Leti egosila na ọ ga-ekwe omume ịmepụta transistors nwere ọwa nanopage asaa ma n'otu oge ahụ tinye ọwa na obosara achọrọ. Dịka ọmụmaatụ, a tọhapụrụ transistor GAA nnwale nwere ọwa asaa na nsụgharị nwere obosara site na 15 nm ruo 85 nm. O doro anya na nke a na-enye gị ohere ịtọ njirimara ziri ezi maka transistor ma kwe nkwa na ha ga-emeghachi omume (belata mgbasa nke paramita).

Dị ka French si kwuo, ka ọkwa ọwa dị na GAA transistor, ka obosara dị irè nke mkpokọta ọwa na, ya mere, njikwa mma nke transistor. Ọzọkwa, n'ụdị multilayer enwere obere ntapu ugbu a. Dịka ọmụmaatụ, transistor GAA dị ọkwa asaa nwere okpukpu atọ dị ala karịa ọkwa abụọ (dị ka Samsung GAA). Ọfọn, ụlọ ọrụ emesịa chọtara ụzọ elu, na-akpụ akpụ site kehoraizin ọnyịnye nke ọcha na mgbawa na vetikal. Ọ dị ka microcircuits agaghị ebuli mpaghara kristal ka ọ bụrụ ngwa ngwa, dị ike na ike rụọ ọrụ nke ọma.
