The Lamp Module Basic Assembly is the radiant heating subassembly used on Applied Materials P5000 process platforms, where banks of high-intensity tungsten-halogen lamps deliver the rapid, uniform thermal energy required to drive chemical vapour deposition and related thermal steps. The “Silver type” designation identifies the reflector and housing finish variant: the polished silver-finish reflector cavity optimises infrared reflectance back toward the wafer plane, maximising radiant coupling efficiency and minimising parasitic heat loss into the surrounding module structure. As a “basic” assembly, this module is supplied as the core lamp-and-reflector building block onto which the system’s wiring, sockets and mounting hardware integrate.
Within the P5000 architecture, lamp modules sit directly above or around the process region, projecting infrared energy through a transmissive window onto the substrate and susceptor. Because deposition rate, film stress and step coverage are all strong functions of wafer temperature, the lamp module is one of the most thermally critical components in the entire tool. A degraded reflector, an open lamp filament or an out-of-tolerance lamp position translates directly into temperature non-uniformity across the wafer and, ultimately, into measurable yield loss.
This listing covers the complete basic module rather than an individual lamp, giving maintenance teams a single, qualified replacement that restores the original radiant profile in one operation. It is a cost-effective alternative to extended downtime caused by progressive lamp ageing or reflector tarnish, and it allows a fab to hold a known-good thermal subassembly in spares inventory ready for swap-out during scheduled preventive maintenance.
The lamp module converts electrical power into controlled infrared radiation, providing the dominant heat source for the wafer and process environment. Its performance defines how quickly the tool reaches setpoint, how tightly temperature is held during deposition, and how repeatably one wafer matches the next. Its principal functions include:
As a high-power radiant device, the lamp module must handle substantial electrical load while maintaining stable, predictable thermal output across thousands of process cycles. Two characteristics dominate its behaviour: the electrical integrity of the lamp circuit and the optical-thermal performance of the reflector system.
The lamp elements draw high current at elevated filament temperatures, so solid electrical connection and clean contact resistance are essential for stable power delivery and accurate closed-loop temperature control.
The silver-finish reflector defines how efficiently radiated energy reaches the wafer and how uniformly it is distributed, making its surface condition central to thermal repeatability.
Because temperature drives deposition chemistry, the condition of the lamp module is directly visible in process results. A module operating outside specification produces effects that ripple through the entire wafer lot:
Tungsten-halogen filaments thin gradually through evaporation and thermal cycling, eventually opening the circuit or drifting in output. An open filament removes a portion of the heating footprint, producing immediate non-uniformity, while a whole bank that has aged together causes a slow, hard-to-diagnose temperature offset.
The silver-finish reflector can lose reflectance over time through oxidation, contamination or heat-induced discolouration. As reflectance falls, less energy reaches the wafer for the same electrical input, forcing higher lamp power, accelerating lamp wear and shifting the achievable temperature profile.
Repeated thermal expansion loosens terminals and oxidises contacts, raising resistance and creating localised hot spots that can scorch insulation or sockets. Insulation breakdown from prolonged high-temperature exposure can lead to intermittent operation, arcing or protective trips during a recipe.
Replacing the lamp module is a planned maintenance activity that should be carried out by trained personnel following Applied Materials procedures and your site’s lock-out/tag-out policy. The following sequence summarises the typical approach:
Holding a qualified lamp module in inventory protects a fab against the unpredictable, throughput-limiting nature of lamp ageing and reflector degradation. ESCT Fab Support helps maintenance teams keep P5000 thermal subsystems running with a sourcing approach built around availability and value:
It is the radiant heating subassembly that converts electrical power into controlled infrared energy to heat the wafer and susceptor during deposition. Its lamps and silver-finish reflector together establish the temperature profile that governs deposition rate, film uniformity and throughput.
No. This is supplied as a new, OEM-compatible part verified to match the form, fit and function of the original Applied Materials assembly. It is not an original OEM part and is not sold as one; it cross-references to OEM P/N 0010-09237 for identification only.
It identifies the reflector and housing finish variant. The polished silver finish provides high infrared reflectance, directing radiant energy efficiently back toward the wafer plane and helping to maintain a uniform, repeatable heating profile.
Typical indicators include temperature drift or non-uniformity, lengthening ramp times, increasing lamp power required to hold setpoint, visible reflector tarnish, or an open lamp element flagged by the control system. Many fabs replace the module proactively during scheduled preventive maintenance to avoid mid-recipe failure.
The typical lead time is 6 weeks. We recommend factoring this into your preventive maintenance and spares planning so that a qualified module is on hand before existing lamps reach end of life.
Yes. Our technical team can review your P5000 chamber and configuration details against the assembly specification to confirm suitability before you order, reducing the risk of a mismatch on installation.
The Lamp Module Basic Assembly (OEM P/N 0010-09237, ESCT P/N ES1044-014) is the radiant heating core of the Applied Materials P5000 thermal subsystem, using tungsten-halogen lamps and a silver-finish reflector to deliver the uniform, repeatable wafer temperature that deposition processes depend on. Because lamp ageing, reflector tarnish and electrical faults degrade gradually and then fail abruptly, holding a qualified module in spares inventory is one of the most effective ways to protect P5000 uptime and yield. ESCT Fab Support supplies this assembly as a verified, cost-effective replacement with technical backing to confirm fit for your configuration.
