A desiccant for semiconductor packaging which may be applied in liquid form consists essentially of approximately 60% by weight absolute ethyl alcohol, 25% by weight ethyl acetate, 5% by weight water, 5% by weight a source of boron, aluminum or phosphorus and 5% by weight of an organic silane having the structural formula: ##STR1## where R. sub. 1 is a radical selected from the group consisting of H. sup. -, CH. sub. 2. dbd. CH. sup. -, CH. sub. 3 O. sup. -, C. sub. 2 H. sub. 5 O. sup. -, CH. sub. 3 CO. sub. 2. sup. -, C. sub. 2 H. sub. 5 CO. sup. -, and C. sub. 3 H. sub. 7 O. sup. -, and R is a radical selected from the group consisting of CH. sub. 3 O. sup. -, C. sub. 2 H. sub. 5 O. sup. -, C. sub. 3 H. sub. 7 O. sup. -, CH. sub. 3 CO. sub. 2. sup. -, C. sub. 2 H. sub. 5 CO. sub. 2. sup. -, Si. sup. +, OH. sup. -, and O. sup. -. The sources of boron, aluminum, and phosphorus may be halides, oxides or nitrates. Also a process for incorporating the foregoing into semiconductor package and process for formulating the above solution.

Improved stabilization of 1,1,1-trichloroethane is obtained by employing a free radical scavenger as a stabilizer which will trap trichloromethyl radicals, making them unavailable for formation of acidic species in the trichloroethane. Examples of such free radical scavengers include trichloroethylene, tetrachloroethylene, or fluorene. Compositions in accordance with the invention consist essentially of the 1,1,1-trichloroethane and from about 0. 1 volume percent to about 5 volume percent of the free radical scavenger. In the fabrication of semiconductor devices in which the so stabilized trichloroethane is employed as a degreasing solvent, the acidity of the trichloroethane composition may be monitored, and additional free radical scavenger added to the solution to maintain the acidity within acceptable limits, thus allowing the trichloroethane to be used indefinitely.

A process is described for the doping of semiconductors utilizing laser beam melting of the semiconductor surface in the presence of a dopant source. By selecting the laser wavelength to satisfy one of several criteria relating the semiconductor absorption coefficient and wafer thickness, or the dopant thickness and doping depth, the heating and melting are constrained to occur in a small local region near the surface where the laser beam impinges. Use of this invention to produce Zener diodes having abrupt doping profiles, as well as other device structures, is also discussed.
