Photoelectric integrated device and manufacturing method thereof

The present disclosure relates to a method for manufacturing a CMOS structure. A first gate stack is formed on a semiconductor substrate in a first region. A second gate stack is formed on the semiconductor substrate in a second region. A dopant of a first type is implanted with the first gate stack and the second gate stack as a hard mask to form a lightly-doped drain region of the first type. A dopant of a second type is implanted by using a first mask and with the second gate stack as a hard mask to form a lightly-doped drain region of the second type. The first mask blocks the first region and exposes the second region. When the lightly-doped drain region of the second type is formed, the dopant of the second type over dopes a predetermined region of the lightly-doped drain region of the first type.

Method for manufacturing CMOS structure

The present disclosure relates to a method for manufacturing a CM OS structure. Shallow trench isolation is formed in a semiconductor substrate. A first region is defined for a first MOSFET and a second MOSFET of a first type and a second region is defined for a third MOSFET and a fourth MOSFET of a second type, by shallow trench isolation. First to fourth Gates sacks are formed on the semiconductor substrate, each of which includes a gate conductor and a gate dielectric and the gate dielectric is disposed between the gate conductor and the semiconductor substrate. The first and second gate stacks are formed in the first region, and the third and fourth gate stacks are formed in the second region. The gate dielectrics of the first and third gate stacks have a first thickness, and the gate dielectrics of the second and fourth gate stacks have a second thickness larger than the first thickness. Some masks are commonly used in various steps in this process so that the number of the masks is reduced.
