The disclosed embodiments provide various compensated charge pumps (CPs) which have a current mismatch compensation circuitry and various CP output-current-mismatch compensation structures based on using a dummy charge pump (CPdum) and feedback loops.

Because CP and CPdum have identical biasings and are compensated in the same manner with the same amount of current, CP output current mismatch is hence effectively eliminated.

A top sacrificial spacer is formed upon the fin and the trench region and etched to form a trench in the trench region. An indentation is formed within the SiGe layer in the trench region, and a sacrificial inner spacer is formed within the indentation. A source/drain (S/D) region is formed within the trench. The sacrificial top spacer and sacrificial inner spacer are etched to form an inner spacer cavity between the S/D region and the SiGe layer. An inner spacer is formed within the inner spacer cavity.

US12154944B2 Super junction power device
The present invention provides a power device with super junction structure (or referred to as super junction power device). When making a super junction power device, impurity of a second conductive type may be implanted into an epitaxial layer of a first conductive type to form a floating island of the second conductive type and a pillar of the second conductive type successively through a super junction mask (or reticle) after forming the epitaxial layer of the first conductive type, directly through a well mask (or reticle) before or after forming a well of the second conductive type, and directly through a contact mask (or reticle) before or after forming a contact structure. Multiple epitaxial processes and deep trench etching process may not be needed. Therefore, the process is simple, the cost is low and yield and reliability are high. Because the super junction power device of the present invention has both the floating island of the second conductive type and the pillar of the second conductive type, in open state, a breakdown voltage may be raised and both Miller capacitance and input capacitance can be decreased and in on state, an on-state resistance can be decreased.
