Abstract
Abstract A semiconductor device which comprises an insulating flexible substrate having conductors extending on one side of the foil from the edge to near the center. A semiconductor element is connected with its contacts connected to the ends of the conductors at the center of the foil. On the side of the foil remote from the conductors a reinforcement member is provided which is present at least near the edges of the foil, the reinforcement member being connected in an adhering manner to the foil and having a pre-shaped contour so as to bend the foil in such manner that the surface of the semiconductor element remote from the foil and the ends of the conductors situated near the edges of the foil are situated substantially in the same plane.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A semiconductor device comprising an insulating flexible foil having conductors on one side of the foil extending from the edge towards the center, and a semiconductor element having contacts which are connected to the ends of the conductors at the central portion of the foil, characterized in that a reinforcement member is provided on the side of the foil remote from the conductors which is present at least near the edges of the foil, said reinforcement member being connected to the foil in an adhering manner and having a pre-shaped contour so as to bend the foil in such manner that the surface of the semiconductor element remote from the foil and the ends of the conductors situated near the ends of the foil are situated substantially in the same plane.
Claim 2
Dependent Claim
131 words
A semiconductor device comprising an insulating flexible foil having conductors on one side of the foil extending from the edge towards the center, and a semiconductor element having contacts which are connected to the ends of the conductors at the central portion of the foil, characterized in that a reinforcement member is provided on the side of the foil remote from the conductors which is present at least near the edges of the foil, said reinforcement member being connected to the foil in an adhering manner and having a pre-shaped contour so as to bend the foil in such manner that the surface of the semiconductor element remote from the foil and the ends of the conductors situated near the ends of the foil are situated substantially in the same plane.
Claim 3
Dependent Claim
62 words
A semiconductor device as claimed in claim 1, characterized in that the reinforcement member comprises a synthetic resin which is provided on the foil and is cured in a contour in which the surface of the semiconductor element remote from the foil and the ends of the conductors situated near the edges of the foil are situated substantially in the same plane.
Claim 4
Dependent Claim
39 words
A semiconductor device as claimed in claim 1, characterized in that the reinforcement member is a profiled stiff strip which is connected to the foil in an adhering manner, the profile corresponding to the desired bend of the foil.
Claim 5
Dependent Claim
62 words
A semiconductor device as claimed in claim 1, characterized in that the reinforcement member is an annular element which is secured to the foil near the edge in a position of the foil in which the rear side of the semiconductor element and the ends of the conductors situated near the edges of the foil are situated substantially in one flat plane.
Claim 6
Dependent Claim
25 words
A semiconductor device as claimed in claim 2, characterized in that the reinforcement member is a lacquer, which cures under the influence of ultraviolet light.
Claim 7
Dependent Claim
20 words
A semiconductor device as claimed in claim 2, characterized in that the reinforcement member is a glass fiber-reinforced polyester resin.
Claim 8
Dependent Claim
27 words
A semiconductor device as claimed in claim 4, characterized in that the space between the annular element and the foil surface is filled with a synthetic resin.
