摘要: A lead frame having a recessed die bond area. The lead frame has top and bottom surfaces and a first lead frame thickness defined as the distance between the top and bottom surfaces. The lead frame has a die bond area surface located within a reduced die bond area. A second thickness is defined as the distance between the die bond area surface and the bottom surface. The second lead frame thickness is less than the first lead frame thickness such that a semiconductor die disposed and attached to the die bond area surface has a reduced overall package thickness. A side wall formed between the die bond area surface and the top surface contains the adhesive material used to attach the die, which reduces adhesive bleeding and prevents wire bonding contamination.

摘要: A lead frame for providing electrical interconnection to a semiconductor die has a generally rectangular flag area having first and second major surfaces and four sides. The flag area is sized and shaped to receive a semiconductor die on one of the first and second major surfaces. A first row of leads is located adjacent to a first one of the four sides of the flag area and a second row of leads is located adjacent to a second one of the four sides of the flag area, where the second one of the four sides is adjacent to the first one of the four sides. The remaining two sides do not have any adjacent leads.

摘要: A molded surface mount semiconductor device has electrical contact elements disposed in a set of pairs of zigzag rows extending adjacent and generally parallel to opposite edges of an active face of a semiconductor die. Each of the pairs of rows includes an inner zigzag row of electrical contact elements nested inside an outer zigzag row of electrical contact elements. The electrical contact elements of the inner and outer zigzag rows are partially inter-digitated. A lead frame used in making the device also has a die pad located inside the set of pairs of zigzag rows, and an outer frame element located outside the set of pairs of zigzag rows, and which support the electrical contact elements of the inner and outer zigzag rows respectively.
