A semiconductor device package includes an electronic component. The electronic component has an active surface, a back surface opposite to the active surface, and a lateral surface connected between the active surface and the back surface. The electronic component has an electrical contact disposed on the active surface. The semiconductor device package also includes a redistribution layer (RDL) contacting the back surface of the electronic component, a first dielectric layer surrounding the electrical contact on the active surface of the electronic component, and a second dielectric layer surrounding the lateral surface of the electronic component and the first dielectric layer. The second dielectric layer has a first sidewall in contact with the lateral surface of the electronic component and a second sidewall opposite to the first sidewall. The second sidewall of the second dielectric layer has a first portion proximal to the RDL and a second portion distal from the RDL. The first portion and the second portion define a stepped feature on the second sidewall. A method of manufacturing a semiconductor device package is also disclosed.
