Tlhoekiso le Limmapa

Ts'ebeletso ea rona e akaretsa tlhoekiso le 'mapa oa lisebelisoa tse fapaneng tsa semiconductor, ka sepheo sa ho fana ka lisebelisoa tsa boleng bo holimo tsa semiconductor bakeng sa lits'ebetso tse fapaneng.Ka ho sebelisa theknoloji ea rona e tsoetseng pele ea tlhoekiso le lisebelisoa tsa morao-rao, re felisa litšila ka katleho, kahoo re ntlafatsa bohloeki ba thepa ea semiconductor.Ts'ebetso ea rona ea tlhoekiso e entsoe ka makhethe, e kenyelletsang mehato e mengata le mehato e tiileng ea taolo ea boleng ho netefatsa bohloeki bo ikhethang le botsitso ba lisebelisoa tseo re fanang ka tsona.

Ho feta moo, re ikemiselitse ho fa bareki ba rona litšebeletso tsa 'mapa tse nepahetseng le tse tšepahalang.Re na le lisebelisoa tse tsoetseng pele tsa tlhahlobo le lisebelisoa, 'me re tšehetsoa ke sehlopha sa litsebi tse nang le boiphihlelo, re khona ho etsa litekanyo tse felletseng le ho sekaseka litšobotsi tsa thepa ea semiconductor.Litšebeletso tsa rona tsa 'mapa li kenyelletsa liteko tse ngata tse fapaneng, ho kenyeletsoa thepa ea motlakase, sebopeho, bohloeki, thepa ea 'mele, le lipatlisiso tse felletseng mabapi le sebopeho sa thepa le sebopeho.Ka ho etsa limmapa tse hlokolosi, re bokella lintlha le lintlha tse qaqileng, tse re thusang ho fa bareki litlhahlobo tse nepahetseng tsa litšobotsi tsa thepa le likhothaletso tse nepahetseng.
