Claim 1
Independent Claim
80 words
A reinforced semiconductor package, comprising: a semiconductor die and leads encapsulated in packaging material, said packaging material defining a pair of opposed major surface; reinforcing and heat sinking ridges disposed in the packaging material and extending outwardly from at least one of said pair Of opposed major surfaces; and reinforcing grooves disposed in at least one of said pair of opposed major surfaces of the package and extending into said package from said at least one of said major surfaces.
Claim 2
Dependent Claim
80 words
A reinforced semiconductor package, comprising: a semiconductor die and leads encapsulated in packaging material, said packaging material defining a pair of opposed major surface; reinforcing and heat sinking ridges disposed in the packaging material and extending outwardly from at least one of said pair Of opposed major surfaces; and reinforcing grooves disposed in at least one of said pair of opposed major surfaces of the package and extending into said package from said at least one of said major surfaces.
Claim 3
Dependent Claim
19 words
