Stress tests of the 2k^2 proptotypes at IFAE
Friday, Jan 14, 2022
The 2K^2 prototypes have been tested at IFAE. One of the devices has undergone 15 thermal cycles (between 50 Kelvin and room temperature) and another one is already at more than 20 cycles. The devices, after the initial set and stress show good stability in the bonds with minimal degradation. Additional thermal cycle tests will continue for the next weeks.

Mock-up and process improvement for the hybridization (WP3) and manufacturing of ALFA detector were done leading to the delivery of the first 2K² prototype based on ALFA detector to IFAE (WP4). These detectors will be tested for reliability under variable temperature environment. 2K² based on ALFA detector (2048x2048 15µm)

Friday, Feb 12, 2021
Lynred is engaged on the development of HgCdTe materials (WP2) in cooperation with CEA-LETI. Recently, Lynred has produced the first PV batch of small TV format with SWIR p/n technology. For that purpose, HgCdTe epilayers were manufactured at Lynred. The p/n PV batch wafers are dedicated to technology performance assessment. The first sorting tests of the dices are performed at CEA-LETI and the fine measurement will be done at CEA-IRFU.

Debonding of temporary mounted wafer stack turned out to be challenging within the project – Final solution found with Laser Debonding performed on EVG®850 DB Automated Debonding System! Two different debonding techniques have been studied throughout the Asteroid project working with 150 mm and 200 mm wafer sizes. Slide-off Debonding Technique Challenge due to brittle stack and CTE issues triggered by debonding temperature causing breakage of the ROIC layer Laser Debonding Technique Optimum debond performance with this brittle stack and no issues with the ROIC layer; tested with 150 mm material and 200 mm material is on the way
