Publication number: 20250125228Abstract: A semiconductor die is arranged at a die mounting region at a first surface of a die pad in a substrate. The die pad has a second surface opposite the first surface. Laser beam energy is applied to the second surface of the die pad to form in the second surface of the die pad a recessed peripheral portion surrounding a central portion opposite the die mounting region at the first surface. An encapsulation of electrically insulating material is molded onto the substrate. During molding, the electrically insulating material covers the recessed peripheral portion and leakage of the electrically insulating material over the central portion is countered in response to the peripheral portion of the second surface of the die pad being recessed.Type: ApplicationFiled: October 9, 2024Publication date: April 17, 2025Applicant: STMicroelectronics International N.V.Inventors: Guendalina CATALANO, Alessandro MELLINA GOTTARDO, Alberto ARRIGONI

Publication number: 20240332106Abstract: A semiconductor die is arranged at a first surface of a die pad. The die pad has a peripheral edge and a second surface opposite to the first surface that includes a first region and a second region surrounding the first region. The second region extends to the peripheral edge of the die pad from a border line at the first region and includes a recessed formation extending continuously along the border line. An insulating encapsulation is molded onto the die pad with the first region of the second surface left uncovered and the second region of the second surface of the die pad being covered by the insulating encapsulation that fills the recessed formation. The recessed formation has a variable recess depth between the border line and the peripheral edge of the die pad to provide an extended length delamination path from the border line to the semiconductor die.Type: ApplicationFiled: March 25, 2024Publication date: October 3, 2024Applicant: STMicroelectronics International N.V.Inventors: Paolo CREMA, Alberto ARRIGONI
