Furnaces, 4" 4-stack A1, Sintering A1: Post CMOS Tool specifications: 4" substrates only 25 substrates Tool Overview Annealing, in metallurgy and materials science, is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness It is a process that produces conditions by heating and maintaining a suitable temperature, and then cooling. Annealing is used to induce softness, relieve internal stresses, refine the structure and improve cold working properties. The tool consists of a quartz process tube, surrounded by heating coils with three zone spike/profile temperature control, gas injection system, load and unload station, and MUX computer and tube control computers Tool Capabilities: • Sintering (annealing) Metals • Hydrogen drive-in gas • Post CMOS Tube • Configured for 4” wafers • Can process any number of wafers from 1 to 25 at a time • Allowed Metals: aluminum, nickel, tantalum, chrome, iridium, molybdenum, tungsten and titanium • Metals Not Allowed: Gold, copper, lead, tin, and platinum • Organics (example polyimide) are never allowed in this tube. • You cannot go into any other furnace tube except C2 after you have been in A1 A2, Boron-dope (deposition) A2-4: CMOS only No metals, glass substrates, III-V material, and no wafers that have previously been in SG RIE/right chamber Plasma Therm/”Dirty” oven. 24 substrate one side doped/11 substrates both sides doped. Tool Overview Diffusion is the spontaneous net movement of particles from an area of high concentration to an area of low concentration Diffusing molecules will move randomly between areas of high and low concentration but because there are more molecules in the high concentration region, more molecules will leave the high concentration region than the low concentration one. Therefore, there will be a net movement of molecules from high to low concentration. Initially, a concentration gradient leaves a smooth decrease in concentration from high to low which will form between the two regions. As time progresses, the gradient will grow increasingly shallow until the concentrations are equalized. The tool consists of a quartz process tube, surrounded by heating coils with three zone spike/profile temperature control, gas injection system, load and unload station, and MUX computer and tube control computers.

The process is often used in the semiconductor industry to produce thin films. In a typical CVD process, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit. Frequently, volatile byproducts are also produced, which are removed by gas flow through the reaction chamber.

The impurities are dependent upon the type of semiconductor. Lightly and moderately doped semiconductors are referred to as extrinsic. A semiconductor which is doped to such high levels that it acts more like a conductor than a semiconductor is called degenerate.
