The advantages of Silicon-on-Insulator (SO) devices over bulk Silicon devices are well known (speed, radiation hardened, packing density, latch up free CMOS,). In recent years, much effort has been made to form a thin, buried insulating layer just below the active device region. Several approaches are being developed to fabricate such a buried insulating layer. One viable approach is by high dose, high energy oxygen implantation directly into the silicon wafer surface (1-3). With proper implant and annealing conditions, a thin stoichiometric buried oxide with a good crystalline quality silicon overlayer can be formed on which an epitaxial layer can be grown and functional devices and circuits built. As SO1 circuits become market viable, mass production tools and techniques are being developed and evaluated. Of particular interest here is the evaluation of high current oxygen implantation with rapid thermal processing on the electrical characteristics of the oxide-silicon interfaces, the silicon overlayer and the thermally grown oxide on the top surface using measurements on gated diodes and guarded capacitors.

ABSTRACTRecent activities in rapid thermal processing on III-V compound materials are reviewed with primary focus on its application to high-speed GaAs integrated circuits. Advantages of the rapid thermal processing are discussed, from the viewpoint of doping characteristics obtained both for n-type channel implants and for high dose n-type contact implants. Enhanced electrical activation is demonstrated by optimizing the encapsulating material employed for annealing high-dose Si implants. Not only these advantages, but also several problems, which should be solved before this technology can be fully utilized in industrial applications, are discussed. Special attention is devoted to improvement in the activation uniformity over a complete 2 inch diameter GaAs wafer.

Short Time

ABSTRACTRapid Thermal Processing (RTP) is used to study shallow junction formation for high dose implanted silicon. The residual damage from As damage is efficiently removed using high temperature-short time anneals (1100°C - few seconds), while limited arsenic atom diffusion is obtained. The diffusion properties are also characterized by concentration enhanced diffusion at higher doping. The higher doping is metastable, with reversible changes in resistivity observed for sequential 1100°C-800°C-1100°C-800°C thermal cycles. RTP gives shallower defect free As junctions than standard long time anneals. Boron junctions are limited by the depth extension of a large ion-channeling-tail which is shown to undergo local enhanced diffusion. The approaches to form shallow p+ junctions without channel tails are discussed. A summary of ion damage studies is made. Some generalizations for determining an RTP advantage or disadvantage are made, based on activation energy differences of effects.

ABSTRACTRapid thermal processing using halogen lamps was applied to the diffusion of Zn into GaAs0.6 P0.4:Te from Zn-doped oxide films. The Zn diffusion coefficient of the rapid thermal diffused (RTD) samples at 800°C for 6 s was about two orders of magnitude higher than that of the conventional furnace diffused samples at 800°C for 60 min. The enhanced diffusion of Zn by RTD may be ascribed to the stress field due to the difference in the thermal expansion coefficient between the doped oxide films and GaAs0.6P0.4 materials, and due to the temperature gradient in GaAs0.6P0 4 materials. The Zn diffusion coefficient at Zn concentration of 1.0 × l018 cm−3 was 3.6 × 10−11, 3.1 × 10−11 and 5.0 × 10−12 cm2 /s for the RTD samples at 950°C for 6 s from Zn-, (Zn,Ga)- and (Zn,P)-doped oxide films, respectively. This suggests that Zn diffusibility was controlled by the P in the doped oxide films.
