Abstract: A method includes forming an n-type Fin-Field Effect Transistor (FinFET) and a p-type FinFET. The forming of the n-type FinFFT includes: forming a first auxiliary gate stack over a first semiconductor fin; forming an n-type source/drain region on the first semiconductor fin; forming a patterned interlayer dielectric (ILD) layer over the n-type source drain; depositing a first protection layer over the patterned ILD layer and the n-type source/drain region; and performing a first etch through the first protection layer. The forming of the p-type FinFET includes: forming a second auxiliary gate stack over a second semiconductor fin; forming a p-type source/drain region on the second semiconductor fin; forming the patterned ILD layer over the p-type source drain region; depositing a second protection layer over the p-type source/drain region; and performing a second etch though the second protection layer.

Abstract: A method includes forming an n-type Fin-Field Effect Transistor (FinFET) and a p-type FinFET. The forming of the n-type FinFFT includes: forming a first auxiliary gate stack over a first semiconductor fin; forming an n-type source/drain region on the first semiconductor fin adjacent to the first auxiliary gate stack; and performing a first etch to form a first recess with a first depth on a first top surface of the n-type source/drain region. The forming of the p-type FinFFT includes: forming a second auxiliary gate stack over a second semiconductor fin; forming a p-type source/drain region on the second semiconductor fin adjacent to the second auxiliary gate stack; and performing a second etch to form a second recess with a second depth on a second top surface of the p-type source/drain region. The first depth is greater than the second depth.

Abstract: A semiconductor package includes a semiconductor die including an active surface and an electrical terminal on the active surface, and a redistribution circuitry disposed on the active surface of the semiconductor die and connected to the electrical terminal. A top surface of the redistribution circuitry includes a planar portion and a concave portion connected to the planar portion, the concave portion is directly over the electrical terminal, and a minimum distance measured from a lowest point of the concave portion to a virtual plane where the planar portion is located is equal to or smaller than 0.5 ?m.

Abstract: A method of manufacturing a semiconductor package includes forming an encapsulated semiconductor device and forming a redistribution structure over the encapsulated semiconductor device, where the encapsulated semiconductor device includes a semiconductor device encapsulated by an encapsulating material. Forming the redistribution structure includes forming a first dielectric layer on the encapsulated semiconductor device, and forming a first redistribution circuit layer on the first dielectric layer by a plating process carried out at a current density of substantially 4˜6 amperes per square decimeter, where the first dielectric layer comprises a first via opening. An upper surface of the first redistribution circuit layer filling the first via opening is substantially coplanar with an upper surface of the rest of the first redistribution circuit layer.
