Publication number: 20230129699Abstract: An integrated circuit (IC) package includes a die having a interface region situated on a surface of the die. The interface region is configured to be exposed to an environment of the IC package. The IC package also includes a metal wall mounted on the surface of the die that circumscribes the interface region and extends from the surface of the die to a wall height. The metal wall has a first region and a second region that is stacked on the first region, the first region having a first thickness and the second region having a second thickness. The second thickness is greater than the first thickness. The IC package further includes a molding encasing a remaining portion of the die. The molding has a height that extends from the surface of the die to a level that is less than the wall height of the metal wall.Type: ApplicationFiled: October 22, 2021Publication date: April 27, 2023Inventors: Rafael Jose Lizares Guevara, John Carlo Cruz Molina
