As anticipated, the upgrade work required a total of two months of off-line work. This scheduled work is now completed, and the MBE system is back in service, growing wafers for use in further POET device work.
Geoff Taylor, Chief Scientist of the Company, notes, “With the old MBE system, we had demonstrated the short wavelength optical capabilities of our process, mainly for datacentre applications. With our newly upgraded MBE system, our capabilities have expanded to fabricating optical devices with long wavelengths. This is critical for our POET offerings in the long-haul, networking and optical equipment market.”
PET Technology Design Kit (TDK)
This PET/TDK milestone (MS-12) focuses on devices requiring only the electronic subset of the POET process; PET offers lower cost and simpler process fab options for applications that do not require the full POET optical feature set. The PET/TDK allows the company to deliver its technology to fab partners and customers, and enable further innovation to integrate both analogue and digital functions together – an application that is said to be not possible today using silicon CMOS.
The PET/TDK milestone is progressing well, and as planned. As noted previously, the addition of Daniel DeSimone to the team has allowed this activity to remain on track, while other activities progress in parallel.
Moving PET/TDK forward requires optimising POET Tech’s process technologies and devices using computer-aided design (TCAD) simulation. Specific TCAD efforts focus on complementary hetero-structure field-effect transistors (HFETs) and bipolar transistors (HBTs). This design basis will support complementary HFET (CHFET), bi-CHFET, bipolar and thyristor device fabrication.
CMOS technologies, both existing today and on the industry roadmap. PET/TDK models will be available to third parties around the end of the third quarter 2014.
Copetti notes, “Thanks are due to Dr. Taylor and the entire technical team for their dedication and relentless focus on the multiple milestones the Company has set for them.”
He adds, “While timelines have had to accommodate challenges in our drive to 100-nm, I am encouraged by the significant recent progress, especially in parallel with our PET/ TDK achievements. Our potential partners and customers have noted this significant progress, and this has allowed me and my executive team to have very detailed discussions with them under non-disclosure agreements, many of them ongoing at this time.”
By enabling increased speed, density, reliability, power efficiency, and much lower bill-of-materials and assembly costs, the POET semiconductor platform is expected to provide disruptive performance with an industry-compatible transition framework, and positions the company as a player in the new generation of companies defining the growth paradigm in the post-Moore’s Law world.
SEMI-GAS expands mini gas enclosure line
The custom gas system performs automatic gas cylinder switchover and is suited to low flow applications or reactors operating in a limited space
SEMI-GAS Systems, a provider of ultra-high purity gas delivery equipment used in MOCVD growth, has launched the new model MGE-XS to its Mini Gas Enclosure product line.
MGE-XS Mini Gas Enclosure
Created to store and deliver ultra-high purity process gases from small gas cylinders, this new Xturion custom gas system also incorporates automatic cylinder switchover capabilities to help minimise manufacturing down-time and operator interaction.
With the addition of the new MGE-XS, SEMI-GAS’ MGE line now comes in two process models, each with two separate compartments housing two individual manifolds with separate purge inlets and vent outlets. The MGE-XS houses four process cylinders, providing two independent automatic switchover systems, in one compact package. While the original MGE-X houses two process cylinders and two dedicated purge cylinders.
Ideal for customers who have low flow applications or are operating in limited space, the MGE-XS is small, measuring 69” high by 32” wide by 27” deep.
The new mini gas enclosure line features an ergonomically bottom-mounted SEMI-GAS GigaGuard GSM Controller with 4.3” colour touchscreen, making cylinder changes and system status monitoring easy.
The GSM oversees all of the system’s operations, including the monitor and control of all process and purge gas electrical components and pneumatically actuated valves. The controller can function independently or with an optional kit that can
