The modulus and hardness of the low-k films can be improved without adversely impacting the k value using MSA. In this article the terms LSA and MSA are used interchangeably. For laser spike annealing temperatures above 1000 C , mobility is found to degrade due to partial relaxation and dislocation formation in the Si _0.3 Ge _0.7 channel. For short-wavelength 1.E-05 MSA tools such as Flash Anneal (FA) or diode laser annealing (a) (a) (DL) the WID temperature range can be anywhere from 100- 1.E-06 250oC, and is highly dependent on device layout. The term "amplification conditions", as used herein, refers to conditions that promote annealing and/or extension of primer sequences. For example, studies on SiGe/Si heterostructures have shown that MSA can enable a higher annealing temperature than RTA, without strain relaxation or structural degradation. - Thermal stress.

The thickness of the internal oxide layer is determined by the highest temperature reached by the surface of the metal during its heating; however, in most instances, it will remain below 3000 Ao (300nm). 257 18 In addition, LSA using multiple beams, which can control the depth of the activation area by using different wavelengths, is also being actively studied to anneal the confined area . LSA Flash Anneal / Diode Laser We pulse the laser. "So the work we have done is in developing processes to integrate the laser-annealing technology into a complementary metal-oxide semiconductor process," Talwar said. 442 0 obj <> endobj The firm's LSA100 and flagship LSA101 tools can be used to make ultra-shallow junctions and highly activated source/drain contacts in both logic chips and LEDs, states the company on its web site. As the layer gets thicker, more light is absorbed (and less is reflected). The standard LSA101 configuration utilizes a single narrow laser beam to heat the wafer surface from substrate temperature to the peak annealing temperature. Since the thermal stress is localized, the backside can be chucked to facilitate heat sinking. Between these two technologies, the choice is not always easy. Based on laser-annealing technology developed at Stanford University (Stanford, CA) and Lawrence Livermore National Laboratory (Livermore, CA), engineers at Ultratech Stepper (San Jose, CA) have progressed to an alpha product level in a tool to fabricate significantly shallower and more abrupt transistor junctions than are currently available through rapid thermal processing (RTP). Simulated temperature distribution in silicon substrate by millisecond nonmelt scanning laser (left) and flash lamp heating (right).
