  • Publication number: 20230221645
    Abstract: A multi-spray RRC process with dynamic control to improve final yield and further reduce resist cost is disclosed. In one embodiment, a method, includes: dispensing a first layer of solvent on a semiconductor substrate while spinning at a first speed for a first time period; dispensing the solvent on the semiconductor substrate while spinning at a second speed for a second time period so as to transform the first layer to a second layer of the solvent; dispensing the solvent on the semiconductor substrate While spinning at a third speed for a third time period so as to transform the second layer to a third layer of the solvent; dispensing the solvent on the semiconductor substrate while spinning at a fourth speed for a fourth time period so as to transform the third layer to a fourth layer of the solvent; and dispensing a first layer of photoresist on the fourth layer of the solvent while spinning at a fifth speed for a fifth period of time.

  • Publication number: 20220077330
    Abstract: A solar cell structure includes a semiconductor substrate having a front side and a back side; a pyramid structure disposed on the front side of the semiconductor substrate; a front passivation layer disposed on the pyramid structure; and a first anti-reflection layer disposed on the pyramid structure. The first reflective layer is a multi-layered anti-reflection layer having at least three coating layers. A front electrode is provided on the first anti-reflection layer. A rear passivation layer is provided on the back side of the semiconductor substrate. A second anti-reflection layer is disposed on the rear passivation layer. A back electrode is disposed on the second anti-reflection layer.
