摘要： A process for forming diffused region less than 20 nanometers deep with an average doping dose above 1014 cm−2 in an IC substrate, particularly LDD region in an MOS transistor, is disclosed. Dopants are implanted into a source dielectric layer using gas cluster ion beam (GCIB) implantation, molecular ion implantation or atomic ion implantation resulting in negligible damage in the IC substrate. A spike anneal or a laser anneal diffuses the implanted dopants into the IC substrate. The inventive process may also be applied to forming source and drain (S/D) regions. One source dielectric layer may be used for forming both NLDD and PLDD regions.

摘要： A method for reducing curvature of a wafer having a semiconductor surface. One or more process steps are identified at which wafers exhibit the largest curvature, and/or wafer curvature that may reduce die yield. A crystal damaging process converts at least a portion of the semiconductor surface into at least one amorphous surface region After or contemporaneously with the crystal damaging, the amorphous surface region is recrystallized by recrystallization annealing that anneals the wafer for a time ≦5 seconds at a temperature sufficient for recrystallization of the amorphous surface region. A subsequent photolithography step is facilitated due to the reduction in average wafer curvature provided by the recrystallization.

摘要： Ultra high temperature (UHT) anneals above 1200 C for less than 100 milliseconds for PMOS transistors reduce end of range dislocations, but are incompatible with stress memorization technique (SMT) layers used to enhance NMOS on-state current. This invention reverses the conventional order of forming the NMOS first by forming PSD using carbon co-implants and UHT annealing them before implanting the NSD and depositing the SMT layer. End of range dislocation densities in the PSD space charge region below 100 cm−2 are achieved. Tensile stress in the PMOS from the SMT layer is significantly reduced. The PLDD may also be UHT annealed to reduce end of range dislocations close to the PMOS channel.

摘要翻译： 对于PMOS晶体管，超高温（UHT）超过1200℃退火少于100毫秒会减少范围位错的终止，但与用于增强NMOS导通电流的应力记忆技术（SMT）层不兼容。 本发明首先通过使用碳共注入形成PSD并且在植入NSD并沉积SMT层之前对其进行UHT退火来逆转形成NMOS的常规顺序。 实现了低于100cm-2的PSD空间电荷区域的范围位错密度的结束。 来自SMT层的PMOS中的拉伸应力显着降低。 PLDD还可以进行UHT退火以减少靠近PMOS沟道的范围位错的结束。
