Prolonged silicon carbide integrated circuit operation in …
2016/12/27· The prolonged operation of semiconductor integrated circuits (ICs) needed for long-duration exploration of the surface of Venus has proven insurmountably challenging to date due to the ∼ 460 C, ∼ 9.4 MPa caustic environment. Past and planned Venus landers have been limited to a few hours of surface operation, even when IC electronics needed for basic lander operation are protected with
Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.
