    Description: 20-page report reviews methods available for etching specific layers on wafers and discusses automation techniques and features on one particular automated system. Compares two major etching methods, chemical (wet) and plasma (dry), and discusses areas in need of development. Methods covered include "dip-and-dunk" manual method of chemical etching, automated chemical etching, and plasma etching.

    Description: Report reviews chemical vapor deposition (CVD) for processing integrated circuits and describes fully automatic machine for CVD. CVD proceeds at relatively low temperature, allows wide choice of film compositions (including graded or abruptly changing compositions), and deposits uniform films of controllable thickness at fairly high growth rate. Report gives overview of hardware, reactants, and temperature ranges used with CVD machine.

    Description: Report discusses totally-automated oxidation and diffusion facility for fabricating IC's. Several innovations are demonstrated: process controller specifically designed for semiconductor processing; automatic loading system to accept wafers from air track, insert them in quartz carrier, and place carrier on paddle for insertion into furnace; automatic unloading of wafers back onto air track; and boron diffusion using diborane.
