The SiGe region can be an embedded source and drain region, or a compressive SiGe channel layer, or other SiGe regions within a semiconductor device. The SiGe region is exposed to an SC1 solution and excess surface portions of the SiGe region are selectively removed. The SC1 etching process can be part of a rework method in which overgrowth regions of SiGe are selectively removed by exposing the SiGe to and SC1 solution maintained at an elevated temperature. The etching process is carried out for a period of time sufficient to remove excess surface portions of SiGe. The SC1 etching process can be carried out at elevated temperatures ranging from about 25° C. to about 65° C. | 01-14-2010 |
| 20100059764 | STRUCTURE AND METHOD TO FORM MULTILAYER EMBEDDED STRESSORS - A multilayer embedded stressor having a graded dopant profile for use in a semiconductor structure for inducing strain on a device channel region is provided. The inventive multilayer stressor is formed within areas of a semiconductor structure in which source/drain regions are typically located. The inventive multilayer stressor includes a first conformal epi semiconductor layer that is undoped or lightly doped and a second epi semiconductor layer that is highly dopant relative to the first epi semiconductor layer. The first and second epi semiconductor layers each have the same lattice constant, which is different from that of the substrate they are embedded in. The structure including the inventive multilayer embedded stressor achieves a good balance between stress proximity and short channel effects, and even eliminates or substantially reduces any possible defects that are typically generated during formation of the deep source/drain regions. | 03-11-2010 |
| 20110237039 | Methods of Forming P-Channel Field Effect Transistors Having SiGe Source/Drain Regions - Methods of forming p-channel MOSFETs use halo-implant steps that are performed relatively early in the fabrication process. These methods include forming a gate electrode having first sidewall spacers thereon, on a semiconductor substrate, and then forming a sacrificial sidewall spacer layer on the gate electrode. A mask layer is then patterned on the gate electrode. The sacrificial sidewall spacer layer is selectively etched to define sacrificial sidewall spacers on the first sidewall spacers, using the patterned mask layer as an etching mask. A PFET halo-implant of dopants is then performed into portions of the semiconductor substrate that extend adjacent the gate electrode, using the sacrificial sidewall spacers as an implant mask. Following this implant step, source and drain region trenches are etched into the semiconductor substrate, on opposite sides of the gate electrode. These source and drain region trenches are then filled by epitaxially growing SiGe source and drain regions therein. | 09-29-2011 |
| 20110318897 | Method of Forming a Shallow Trench Isolation Embedded Polysilicon Resistor - Forming a polysilicon embedded resistor within the shallow trench isolations separating the active area of two adjacent devices, minimizing the electrical interaction between two devices and reducing the capacitive coupling or leakage therebetween. The precision polysilicon resistor is formed independently from the formation of gate electrodes by creating a recess region within the STI region when the polysilicon resistor is embedded within the STI recess region. The polysilicon resistor is decoupled from the gate electrode, making it immune to gate electrode related processes. The method forms the polysilicon resistor following the formation of STIs but before the formation of the p-well and n-well implants. In another embodiment the resistor is formed following the formation of the STIs but after the formation of the well implants. | 12-29-2011 |
