Abstract (en)

[origin: WO2019074616A2] Techniques are described for forming a semiconductor device by fusing a first PVSK layer on a first portion of the device with a second PVSK layer on a second portion of the device. The portions are stacked together so that the PVSK layers face each other. The PVSK layers can be fused by applying heat or light, together with pressure. The fusing can include adding a solvent or a first PVSK component. The first PVSK component can be a material that lowers a melting temperature of the PVSK in the PVSK layers to assist in recrystallization of the PVSK. The first PVSK component can be combined with a second PVSK component to form additional PVSK. The PVSK components can be added after the PVSK layers are formed or additives within the PVSK layers. PVSK layers can also be fused without adding any components or solvents.
