Features

The ALD150LE™ is configured for purely thermal ALD, and our unique perpendicular flow design enables isolated, uniform precursor delivery with reduced background impurity levels for improved film quality. To avoid unwanted material buildup and particulate formation inside delivery channels, two separate chamber inlets are available for precursor isolation. For example, separate inlets can be used to isolate metal organic precursors and co-reactants to prevent deposition in delivery lines and valves.

  • Two separate inlets for precursor delivery to prevent unwanted buildup in delivery channels
  • Open-load chamber engineered to minimize background impurities due to seal outgassing and permeation
  • Independent substrate heater stage and outer chamber casing for excellent temperature control and uniformity
  • 304L stainless-steel construction
  • Accessible, low maintenance design

The ALD150LE™ open-load design enables manual placement of substrates (up to 150 mm in diameter) directly onto the substrate heater stage during sample introduction. During subsequent ALD processing, centralized precursor delivery and pumping sets up a barrier that keeps impurities from downstream chamber seals out of the reaction zone. The strategic positioning of elastomer chamber seals downstream keeps impurities (due to seal outgassing and permeation) away from substrate surfaces for improved ALD film quality. In particular, this is an important feature for obtaining high quality nitride films in an open-load chamber design.

Precursor Delivery

The base ALD150LE™ system includes two heated, single-source vapor draw modules with two separate chamber inlets (to avoid unwanted buildup in delivery line components), that operate in dynamic or static exposure modes. For the full range of precursor delivery options currently available, please refer to the Options Tab for more information.

Heating

The ALD150LE™ employs superior heating and temperature control that complements our unique perpendicular flow design by further enhancing overall system performance. In particular, temperature uniformity and control helps to prevent unwanted precursor condensation resulting in parasitic effects that reduce film quality and compromise chamber cleanliness.

Upper temperature Limits for heated system components are as follows:

  • Substrate heater stage 500°C
  • Chamber and precursor delivery lines 250°C
  • Precursors and delivery valves 200°C
  • Delivery Line heating up to 250°C
  • Up to 200°C Valve Heating

Our unique heater design combined with independent heat zones for precursors, delivery valves and lines, process chamber (multiple zones), substrate heater as well as foreline components provide unparalleled temperature control and uniformity of heated system components.

Options

Precursor Delivery Options

With up to ten precursor sources that utilize four separate chamber inlets, the ALD150LE™ provides extreme process flexibility. Modules are available for gas, liquid and solid phase precursors with a host of delivery options including vapor draw, flow-through and pulsed gas delivery. A fully integrated ozone delivery option is also available. Please contact us for more information regarding our ozone option.

For delivery options that require heating, our unique heater designs combined with independent heat zones for precursors, delivery valves and lines provide unparalleled temperature control and uniformity. Excellent temperature uniformity and control helps to prevent unwanted precursor condensation resulting in parasitic effects that reduce film quality and compromise chamber cleanliness.

Precursor exposure modes include dynamic, static and Variable Residence Mode™. Dynamic and static modes are standard features; Variable Residence Mode™ is optional. Please contact us for more information regarding our Variable Residence Mode™ option. The modular, scalable ALD150LE™ design accommodates a variety of different configurations including future expansion and upgrades.

Single-Source & Multi-Source Vapor Draw Modules

Vapor draw sources are ideal for liquid and solid phase precursors with sufficient vapor pressure such that they do not require any special assistance for effective vapor delivery other than heating. The base ALD150LE™ system includes two heated, single-source vapor draw modules with two separate chamber inlets (standard feature).

  • Optional multi-source vapor draw module (replaces one of the base single-source modules)
  • Multi-source vapor draw module can include up to five vapor draw sources
  • Precursor and delivery valve heating are independently controlled up to 200°C
  • Delivery lines are independently controlled to 250°C
  • Vapor draw modules feature true precision ALD valve timing for optimal precursor dose control

Flow-Through Vapor Delivery Module

For liquid and solid phase precursors with insufficient/low vapor pressure, flow-through sources provide enhanced vapor delivery. Our unique, modular flow-through design provides added flexibility for advanced low vapor pressure delivery and supports both flow-through and vapor draw methods. The ALD150LE™ can accommodate up to two flow-through modules.

  • Fully enclosed oven or independently heated precursor cylinder configurations
  • Precursor and delivery valve heating independently controlled up to 200°C (oven configuration not fully independent)
  • Delivery line heating independently controlled to 250°C
  • True precision ALD valve timing for optimal precursor dose control

Pulsed Gas Delivery

Pulsed gas options include our Pulsed Gas Source™ (PGS™) delivery module specifically designed for precise, accurate, high-speed dosing of toxic gases (e.g., WF6, HCl, NH3, H2S, etc.). The KJLC® unique PGS™ design utilizes a fixed charge volume (or reservoir) for precursor dosing that eliminates the he need for a mass flow controller for precise, accurate delivery. To control the amount of precursor being delivered, precision ALD valve timing as well as reservoir pressure, are tightly controlled through our eKLipse™ software and controls package to enable high-speed dosing with both precision and accuracy. The ALD150LE™ can accommodate one PGS™ module.

  • Designed specifically for precise, accurate high-speed dosing of toxic gases (e.g., WF6, HCl, NH3, H2S, etc.)
  • Eliminates the need for mass flow controllers
  • Includes separate channel for pumping and purging of input line components
