A semiconductor device includes a semiconductor wafer having a weak portion and a removable passivation cap disposed on the wafer for covering the weak portion. The passivation cap has an absorption coefficient of a laser beam, which is smaller than that of the wafer. The cap has a capability of passing...http://www.google.es/patents/US6995466?utm_source=gb-gplus-sharePatente US6995466 - Semiconductor device having passivation cap and method for manufacturing the same
