FAQ na BF33 Glass Wafer
Menene gilashin BF33?
BF33, wanda kuma ake kira BOROFLOAT® 33, babban gilashin borosilicate na ruwa ne wanda SCHOTT ke ƙera ta amfani da tsarin microfloat. Yana ba da ƙananan haɓakar thermal (~ 3.3 × 10⁻ K⁻¹), kyakkyawan juriyar girgiza zafin zafi, babban tsaftar gani, da ƙwarewar sinadarai.
Ta yaya BF33 ya bambanta da gilashin yau da kullun?
Idan aka kwatanta da gilashin soda-lime, BF33:
-
Yana da ƙarancin haɓaka haɓakar haɓakar thermal, yana rage damuwa daga canjin zafin jiki.
-
Ya fi juriya ga acid, alkalis, da kaushi.
-
Yana ba da mafi girman watsawar UV da IR.
-
Yana ba da mafi kyawun ƙarfin inji da juriya.
Me yasa ake amfani da BF33 a aikace-aikacen semiconductor da MEMS?
Fadada yanayin zafi ya yi daidai da silicon, yana mai da shi manufa don haɗakar anodic da microfabrication. Dorewar sinadarai kuma yana ba shi damar jure etching, tsaftacewa, da matakan zafin jiki ba tare da lalacewa ba.
