Patent DE-3903855-A1 (DE)
Title: Light-induced dry etching process
Inventor: MATZ RICHARD DR
IPC: G02B6/136
Filed: 1989-02-09
Abstract: Using a pulsed argon fluoride excimer laser with a wavelength of 193 nm, the present process can also be used, for example, for the system, relevant in integrated optics, indium phosphide/indium gallium phosphide arsenide. The etching gas used is preferably hydrogen bromide. The bromides formed as the reaction product in the process on the indium phosphide surface (2) are volatile under equilibrium conditions in vacuo above approximately 110@C. Below this temperature, however, no sharp decline in the etching rate is observed, since the desorption even of the less volatile indium bromide is maintained in this case by thermal and/or electronic excitation from the laser pulse. Over the entire temperature range, the etching rate is determined by the thermally activated reaction rate between the halogen and the indium phosphide. In order to achieve high etching rates, the permanent substrate temperature should therefore be chosen as high as possible without adversely affecting the process in question. The peak temperature occurring in the laser pulse in this case is advantageously close to or above the melting point of the semiconductor material (1062@C for indium phosphide). The process chamber is filled with hydrogen, in addition to the etching gas. As a result, the mean free path is reduced, and edge blurring (4) is diminished. <IMAGE>

Patent DE-3925905-A1 (DE)
Inventor: HOFMANN HERMANN
IPC: C05F17/00
Filed: 1989-08-04
Abstract: A process is used for aerobic, fermentative hydrolysis, particularly for composting organic substances, in a sealed container. Fresh air is introduced to the organic substances.
